micro-air EasyTouch RV 356 True Air RV Thermostat
INTRODUCTION
The EasyTouch RV™ 356 model thermostats were designed to directly replace certain 12-volt Coleman™, Airxcel™, RVComfort™, TrueAir™, and ComfortGuard™ single zone, single/dual-stage compressor, single/dual-stage heater systems. These are typically “basement units” in Winnebago or Alfa brand recreational vehicles. Please use section EasyTouch RV 356 Models and Compatible Replacements to make sure that this model is right for you.
EasyTouch RV 356 Models and Compatible Replacements
EasyTouch RV 356 can be purchased in two colors. Table 1 lists all EasyTouch RV 356 models. The obsolete thermostats are no longer sold, however their only difference was how to wire the unit. There is no need to replace these models as operations and build quality were identical to the latest thermostats.

Table 2 and Table 3 list the known OEM model numbers that can be used
with EasyTouch RV 356. The tables are not exhaustive so if your thermostat is
not listed, please contact Micro-Air https://www.microair.com/SupportRequest
to verify if this is the correct model for your application.
Thermostat model numbers can be found in your original user’s manual and on
the back side of the thermostat or the back of the mounting plate. Note that a
“ * ” character means any character in that position is a match.
A 4-to-3 wire harness is provided with EasyTouch RV 356 that may or may not be
needed. Table 2 are those that do not use this harness, while Table 3
thermostats will. See section Wiring the Thermostat for how and when to use
it, if needed.
The ”Gas Changeover Version ” columns of Table 2 and Table 3 are referenced in
section Auto Gas Changeover Type of the Initial Setup Instructions.
Please refer back here during initial setup.
Included in the Box
EasyTouch RV model 356 is shipped with the following items:
- 1x EasyTouch RV 356 Thermostat
- 1x Quick-Start Guide
- 1x 4-to-3-pin adapter (Figure 1)
- 1x 9-Pin (3×3) adapter (Figure 2)
- 1x Mounting Bracket (Figure 3)
- 4x Screw Hole Covers
The quick start guide can be used to get the thermostat installed and set up
quickly to cool or heat the space.
The mounting bracket and adapters are for installation, though the adapters
are not always used. The screw hole covers can be used to cover holes in the
wall from the previous thermostat if they are exposed.
Installing the Thermostat
Came From Quick Start Guide? – Begin Here
You may have been directed here from the included Quick-Start Guide if it determined that you need to do some additional setup. The directions needed are difficult to express without detail so please read the full installation guide here to install your thermostat. This complete installation guide covers everything in the Quick-Start Guide.
Safety
First, it is recommended to remove both AC and DC power from your system.
Unplug your RV from shore power and turn off any converters or generators to
remove AC power. Open your 12-volt DC bus
breaker or fuse to de-energize your thermostat. This greatly reduces the
chance of any harmful electrical discharge, as well as preventing accidentally
opening a fuse.
Removing the Old Thermostat
The original thermostats have a front cover that pops off. Behind the cover there are 2-4 mounting screws that must be removed to free the back plate, shown by Figure 4. Once the thermostat is removed, pull out some of the wire from the wall to inspect how it was installed.
Some RV builders will use the proper plugs recommended by the original thermostat manufacturer for all the thermostat connections, which is also how EasyTouch RV is designed. This is shown in Figure 5. This means you can simply unplug the thermostat and proceed to the next section. Note that Figure 5 shows only one possible set of plugs and there may find more or different plugs in your system.
Other RV builders do not use the proper plugs and direct wire the thermostat
to the RV manufacturers wiring using wire crimps or similar. Some of them may
use a mix of plugs and direct wire. If the unit is direct-wired fully or in
part then take some pictures of this wiring for reference. Be sure that you
can see where the thermostat wires meet with the wall wires as they are
typically different colors. You can also write in Table 4 later in the section
to record what color wires meet.
Wiring the Thermostat
Molex™ Plugs
If your installation was done with the proper mating Molex™ plugs similar to
Figure 5, then you can simply plug in all the mating connectors and move on to
the section Mounting the Thermostat. The provided 9-pin (3×3) wire harness
will not be needed. Not all installations will use all plugs, just ensure that
every original plug has an EasyTouch match.
You may find the Molex™ plug coming from the wall has a 3-pin plug and EasyTouch comes with a 4-pin plug installed. Use the provided 4-to-3 pin adapter harness (Figure 1) in these systems, where the orange/white wire is not used. If you have a 4-wire plug coming from the wall already then you will not need the 4-to-3 pin adapter harness. If you find the 9-pin (3×3) is used but not a 4-or 3-pin then you will use the relevant Direct-Wired section directions to complete the wiring.
If the plugs are not the standard Molex™ plugs that mate with EasyTouch then you will have to wire it direct as described in the Direct-Wired section. You could also make up your own plugs but is beyond what MicroAir can assist with.
Direct-Wired
The original thermostat in these systems will have wires coming out of the
back of it that are connected to the RV manufacturer’s wiring harness, using a
crimp-splice or similar. The wire colors on the RV manufacturer’s harness can
vary, but the wires at the back of the original thermostat are always the same
color for their use.
Follow the thermostat wires the short distance to where they are spliced to
the RV manufacturer’s wire harness. Write in the RV wiring harness colors in
Table 4 below before making connections. Take pictures if you have not already
for reference as well. Some thermostats and harnesses may not have all wires
shown in Table 4. The important part is that every original wire has an
EasyTouch match.

Micro-Air provides a 9-pin harness (Figure 2) that will be used to interface
between EasyTouch and the RV manufacturer’s wires. One side plugs into
EasyTouch RV while the other wire-end side is used to make your new wire
connections. You will have to source or reuse electrical connectors to make
these connections.
EasyTouch will also have a pre-wired 2-pin connector and a pre-wired 4-pin
connector attached to the back.
Connect the provided 4-to-3 pin adapter harness (Figure 1) to EasyTouch. Strip
away the black heat-shrink on the orange/white stripe wire if the orange/white
stripe wire is used. Cut off the 2-pin and 3-pin plugs as needed and use
electrical connectors (not provided) to complete the installation per Table 4.
Any unused wires or plugs you can cut short or leave untouched.
When you know where each wire goes you should begin cutting wires. Move
through them one at a time, replacing an OEM thermostat wire with the
appropriate EasyTouch wire until all the wires are replaced.
Check for Additional Hardware – Software Setup for Later
You must check your wiring to determine what additional hardware your system may have. Later, you will use these findings to configure the software in EasyTouch RV.
Some of them had a freeze sensor while others used an AGS (Auto-Generator Start) output, but never both. If an AGS system was used, it was often in a Winnebago (TrueAir) thermostat, but a freeze sensor is most common in general. Inspect your OEM thermostat wires (Figure 6) for either two gray wires or a green wire. A green wire means that you have AGS. Two gray wires means that you do not have AGS.
See the Configure Auto-Gen Start section in Initial Setup Instructions to tell the thermostat what you have. If your system is Direct-Wired, use Table 4 to connect your gray wires to the gray wires of the Micro-Air 9-pin harness (polarity does not matter) or connect your green wire to the pin-3 gray wire of the Micro-Air 9-pin harness. Pin-3 is the gray wire next to orange and red.
Re-apply Power
Restore DC power. The thermostat screen should light up and boot into the main
menus. This will happen if the four power wires are connected properly. All
other wires control the outputs or are sensors.
Restore AC power so that your appliances can run again. Move on to the section
Mounting the Thermostat, or the section Initial Setup Instructions and mount
the thermostat later.
Mounting the Thermostat
-
Step 1 : Locate the mounting bracket (Figure 3) horizontally across the hole with the smaller diameter of the mounting button against the wall.
-
Step 2: Screw in one screw and level the buttons so the display will be straight when installed.
Screw into the smaller hole of the two buttons. -
Step 3 : Screw in the second screw and make sure the buttons are flat and level. The larger diameter button has some play to make these adjustments easier.
-
Step 4: Remove the mounting tab before mounting the thermostat on the wall.
-
Step 5: Aligning the buttons with the holes in the back of the display. Press the display against the wall and gently slide the display down to lock it in place.
Initial Setup Instructions
Configure your Available Outputs
EasyTouch RV 356 is meant to replace a few different OEM thermostats and so
must be configured for your system prior to using it. Tap the Settings button
on the main screen, then navigate to the Setup button and tap it. The first
page is to configure the hardware in your specific system. Tap the heat pump
button to enable or disable it based on what is installed in your system. A
red circle with a line through it over the button indicates disabled. Cool and
furnace are always enabled.
Configure Auto-Gen Start (AGS)
Some systems have hardware to allow for a generator to start prior to a cycle
occurring that needs it. These systems are commonly labeled “TrueAir” and are
often found in Winnebago products, but not all have AutoGen Start (AGS). The
hardware for (AGS) is not part of the thermostat but it must be configured to
know if it is available. Use section Check for Additional Hardware – Software
Setup for Later to know what you have.
Tap the AGS Available/Unavailable button under the “Auto GenStart” heading to set it based on what you have. If set as “Available” then the Generator button will appear and you can turn the functionality on or off. Setting this to “Unavailable” is the default and should be used for all nonAGS systems.
Warning: You MUST configure AGS availability appropriately or your thermostat may not function as designed. You CANNOT enable this function unless you know you have the appropriate hardware. See section Check for Additional Hardware – if you are not sure. This can also be found in your original thermostat’s manual. Micro-Air cannot assist with acquiring AGS hardware.
Auto Gas Changeover Type
You can choose the auto gas changeover type by tapping the Type button on the
second page. Each “version” has slightly different logic to use all of your
available heat modes in stages based on how far the inside temperature is from
the set-point. Each version corresponds to a version of the OEM thermostats
behavior, as well as a “Disabled” option. Use the “GC Ver” column of Table 2
and Table 3 to match the version to your original thermostat. “Version A” has
the broadest coverage if not sure.
You can also adjust parameters for the Auto Gas Changeover to operate its logic. The temperature at which stages escalate can be set, as well as the maximum run time for a lower stage to escalate. See section Auto Gas Changeover in section Operating the Thermostat for more details on this operation and the configurable parameters.
Connecting Remotely
EasyTouch RV can be operated entirely by the touchscreen, however you can also communicate, monitor, and modify operation of it wirelessly using the EasyTouch RV application. Some extra features will require a wireless connection and is described in their sections. See Appendix A: Working Wirelessly for details.
Operating the Thermostat
This screen is where most time is spent using the thermostat.
This screen allows you to set and monitor the desired operation of the
thermostat and is shown in Figure 7.
-
Operational Mode
This is the main operating state of the system. Tap it to change to any available mode or turn the system off.
Note: If you do not see a mode you should have then see section Configure your Available Outputs. -
Fan Speed
This sets how the electric fan (not the furnace blower!) will operate in conjunction with the selected (1) Operational Mode. Tap it to iterate the available fan speeds. No fan button means there is no fan control for the selected mode. Not all fan speeds are available for the selected mode.- Full Auto: Turns the electric fan on and off with a cycle. It automatically adjusts the speed based on the difference between setpoint and inside temperature
- Cycled: Turns the electric fan on and off with a cycle at the selected speed only
- Manual: Always runs the electric fan at the selected speed
-
Inside temperature
This is the temperature reading for the space that the thermostat is trying to temper, determined by a local sensor. If a remote sensor is plugged into the back of the thermostat then it has priority over the sensor installed in the thermostat from the factory. Use the (9) Info Screen to determine which is in use. -
Temperature Setpoint
This button shows the current temperature setpoint for the selected (1) Operational Mode. Tap it to adjust the temperature setpoint. Setpoints are tied to each mode to remember the last setting. No setpoint button means there is no setpoint control for the selected mode. -
Settings
This button will enter the settings screens. Settings are mostly for configuring the thermostat and making changes that are not common or found on the main screen. See section Settings Screens for more details. -
WiFi Status
The Wi-Fi indicator shows the state of the thermostat’s Wi-Fi connection. A dark blue icon means no connection to an internet enabling device. Red means it is connected to an internet enabling device but does not have internet. Green means it is connected to the internet. The number of bars indicate strength. See the Connecting to a New Wi-Fi Network for more details. -
Local Weather
This icon indicates the local weather at the last time weather information was received. A Wi-Fi connection on the thermostat is required to get weather data. Tap the icon for more detailed weather information. See the Local Weather and Local Time section for more details. -
Outside Temperature
This is the temperature reading for your local area that is retrieved over the thermostat’s internet connection and is part of the (7) Local Weather information. -
Info Screen
This screen shows information about the thermostat’s operating state. Tap the button for this information. -
Status Message
Various messages may be shown here to indicate active operations. See the Status Messages section for potential messages and their meanings.
Operational Modes
All modes operate the overhead fan and/or a heating or cooling cycle based on
the current heating or cooling setpoint, relative to the inside temperature.
Fans and Fan Only Mode
This mode lets the fan to operate based on the chosen (2) Fan Speed. This will
circulate the air without operating any heating or cooling cycles.
Cool Only Mode
This mode only runs a cool cycle to maintain the cooling set-point in the
space. Set the (1) Operational Mode button to Cool Only and the desired (2)
Fan Speed, where behavior will then be based on Table 5.
Environment ( ° F) | Cycle Operation | Auto Fan Operation |
---|---|---|
Inside ≤ Setpoint | None | Off |
Inside 1° Above Setpoint | Compressor #1 On | On Low |
Inside 2° Or More Above Setpoint | Compressor #1 and #2 On | On High |
Inside Returns 1° Below Setpoint | Compressors Off | Runs 45 More Seconds, Off |
Note: Table 5 operation may be different based on the Gap settings. See section Temperature Gap (Hysteresis) for details.
Heat Pump Only Mode
This mode only runs an electric heat pump heating cycle to maintain the
heating set-point in the space. Set the (1) Operational Mode button to Heat
Pump Only and the desired (2) Fan Speed, where behavior will then be based on
Table 6.
Environment ( ° F) | Cycle Operation | Auto Fan Operation |
---|---|---|
Inside ≥ Setpoint | None | Off |
Inside 1° Or More Below Setpoint | Compressor #1 And #2 On | On High |
Inside Returns 1° Above Setpoint | Compressors Off | Runs 45 More Seconds, Off |
Note: Table 6 operation may be different based on the Gap settings. See
section Temperature Gap (Hysteresis) for details.
Note: All heat modes are subject to Auto Gas Changeover Operation when
enabled. See section Auto Gas Changeover in Operating the Thermostat for
details.
Furnace Only
This mode only runs an auxiliary heating cycle to maintain the heating setpoint in the space. Set the (1) Operational Mode button to Furnace Only or Aqua Only and the desired (2) Fan Speed, where behavior will then be based on Table 7.
Table 7 – Furnace Only Mode Operation
Environment ( ° F) | Cycle Operation |
---|---|
Inside ≥ Setpoint | None |
Inside 1° Or More Below Setpoint | Furnace Stage #1 On |
Inside Returns 1° Above Setpoint | Furnace Stage #1 Off |
Note: Table 7 operation may be different based on the Gap settings. See
section Temperature Gap (Hysteresis) for details.
Note: All heat modes are subject to Auto Gas Changeover Operation when
enabled. See section Auto Gas Changeover in Operating the Thermostat for
details.
Auto Modes
These modes will automatically switch between heating and cooling cycles as
needed. Their operation will be the same as their “only” mode counterparts
described earlier in the Operational Modes section. Auto modes will have their
own “dual” set-points that are separate heating and cooling set-points. No
heating or cooling cycles will occur when the inside temperature is between
the setpoints.
This can be useful when setting a higher day-time cooling temperature and
lower night-time heating temperature. It can also be used to control the
temperature extremes when you are away from the RV.
Note: These auto modes are subject to Auto Gas Changeover and Gap
operations. See their Auto Gas Changeover and Temperature Gap (Hysteresis)
sections respectively for more details.
Auto Gas Changeover
Note: See section Auto Gas Changeover Type in section Initial Setup
Instructions to configure this feature.
Auto Gas Changeover operation mirrors the OEM thermostat’s operation for
additional stages of heat when the thermostat determines more are needed. The
three escalating stages are shown in Table 8. All three stages may not be
available based on your system, but EasyTouch will output the same logic.
Stage 2 heating is available in every system.
Staging | Heat Source |
---|---|
Stage 1 | Heat Pump |
Stage 2 | Furnace 1 |
Stage 3 | Furnace 2 |
The below tables are based on “Version A” type of Auto Gas Changeover, which
is the default selection and should be adjusted as described in the Auto Gas
Changeover Type section. “DISABLED” will turn this behavior off. Other version
changes are noted within the below tables.
The temperature and runtime values can also be adjusted from the same setup
screens where “Type” is set.
Heat Pump and Auto Cool/Heat Pump Changeover Behavior
Table 9 shows how Auto Gas Changeover affects the Heat Pump operational modes
when enabled.
Environment ( ° F) | Operation |
---|---|

Satisfied
or|
Any Stage Runs 20 Minutes (VERSION A AND D ONLY)| Stage Escalates to
the Next Highest Available Stage
|
3 Cycles in a Row Call for Escalation| Stage 2 and Stage 3 will Start Together
for Next Two Hours
Note: Table 10 operation may be different based on the Gap and/or Setup settings. See section Temperature Gap (Hysteresis) and Setup for details, respectively.
Local Weather and Local Time
Local weather is displayed on the main screen whenever Wi-Fi and internet is
available, shown visibly in the Main Screen section. Tapping the button will
reveal more detailed weather information of the last received weather data.
The local temperature is displayed under the local weather.
A valid location and an internet connection on the thermostat are required to
retrieve weather data. Local time data also requires valid location data.
Location is saved in the thermostat when a Bluetooth connection is made from a
smart device with its location services enabled. You can check the current
saved location from the weather screen. Location is preserved through power
losses or device restarts.
New weather data is retrieved when there is any screen press or when a
connection from a smart device is made, along with the above prerequisites.
Time is pulled in when a Bluetooth or Wi-Fi connection is made from the app.
Also, an internet connection on the thermostat will grab the time so long as
there is a valid saved location. If power is interrupted or the device is
restarted, it will go out to the internet to grab the current time when the
internet connection is reestablished, without app interaction.
Tapping the weather icon area, whether there is information there or not, will change to the weather screen that will show the last valid weather data or weather troubleshooting information. If the main screen has a temperature but no weather icon, it is defaulting to the outside sensor reading on thermostats that have one. The information screen will always show the sensor reading if there is a sensor, and the weather screen will always show the temperature reading from the internet. Systems without an outside temperature sensor cannot add one.
Status Messages
Some messages may be displayed on the main screen as shown in section (10) Status Message under Main Screen. Table 11 shows the potential messages and their meaning.
Message Text | Description |
---|---|
OPEN INDOOR SENSOR | The room sensor inside EasyTouch RV has failed |
open/disconnected or shorted. It must be repaired, or replaced by an external
AirXcel OEM remote sensor using the green/white stripe wires of EasyTouch RV.
BAD INDOOR SENSOR
OPEN FREEZE SENSOR| The freeze sensor is open to say that the indoor
coil has frozen up under cooling operation and should be serviced as directed
in the OEM manual for the A/C unit. Cooling operation will resume when the
sensor closes to indicate it has warmed up.
If not, ensure that the sensor is installed to the thermostat correctly on the two gray wires. AGS systems do not use a freeze sensor so ensure that the thermostat is configured properly for AGS systems if used, as described in the Check for Additional Hardware – Software Setup for Later section.
When 120 Volts AC is removed, the sensor no longer operates as expected and reads open. This is OK and just a nuisance fault. The fault will clear when power is restored. Power is needed to run electric appliances and the furnace will run if the freeze sensor is open.
Also check that the fuse at the back of the thermostat is still good. Appliances cannot turn on with an open fuse and the freeze sensor circuit will read open.
AUX HEAT ENABLED| This means that the two-hour timer of the Auto Gas Changeover logic is active. See the Auto Gas Changeover section in Operating the Thermostat for details.
Settings Screens
The settings screens allow for further configuration and control of the thermostat. It is a paged system that you can navigate through to see all available settings. Each setting button can be tapped to configure the related settings. Note: Not all settings may be available depending on your EasyTouch RV model. If you do not see the graphic then it is not available for your system.
Tap the settings button as shown in section (5) Settings under Main Screen to view them
Navigation

main screen.
System Help
This screen displays a QR code that can be scanned to provide information about thermostat operation and troubleshooting from the Micro-Air website. It also shows the current thermostat firmware revision and the thermostat serial number.
Day/Night Mode (Screen Saver)
Tap this icon to switch between Day or Night mode. Day mode will dim the
display down to the Sleep Level set in the Display Brightness settings, after
30 seconds of no screen presses. Night mode will turn the backlight completely
off after 30 seconds of no screen presses. The display will brighten again
after a screen press to the Active Level set in the Display Brightness
settings.
Display Brightness
This screen allows you to set the Active and Sleep brightness levels that are
used by the Day/Night Mode (Screen Saver) settings. Tap the associated up and
down arrows to change their level.
Schedule – Edit, Enable or Disable
There are two Schedule buttons with sub-writings “Schedule” or
“Enable/Disable”. Tap the enable/disable button to turn the schedule on or
off. Tap the schedule button to modify the schedule. See section Schedule
Screens for more details.
Wi-Fi Information
This screen allows you to monitor the state of your Wi-Fi connection to the
thermostat. SSID and Password fields shows the saved credentials that the
thermostat is always attempting to find and connect to. Tap the password field
to reveal the password.
The Router, Strength, and Internet fields show the state of the Wi-Fi connection. The MAC address of the thermostat is also shown at the bottom. See section Connecting to a New WiFi Network for more details about using Wi-Fi.
Home/Away
This setting changes from a home memorized set of settings to an away
memorized set of settings. It is like having two different thermostats, one
while you are at the RV and one for when you are not. Each can be set with a
completely different set of modes, schedules, set points and fan speeds to
customize the operation with a single button press.
Bluetooth (Account) Password Reset
This screen is used to reset the saved Bluetooth password in the thermostat.
This is the password that must match your EasyTouch RV app account to make
remote connections. Only one account can have access to the thermostat. Use
this whenever you reset the password to your app account to regain remote
access to the thermostat.
Temperature Reading Adjustment
This setting allows you to calibrate the Inside temperature reading with an
offset. For example, if the inside temperature reads 72°F (22.2°C) and you
feel it is 75°F (24°C), you can use the up and down arrows on this page to
increment the offset to +3°F (+1.8°C).
Temperature Gap (Hysteresis)
This setting determines the difference in temperature required between
setpoint and inside temperature before a heating or cooling cycle will begin.
This is helpful to prevent short cycling in large spaces or spaces with high
thermal loss, by running a cycle for longer amounts of time. This offset is
applied to all logic that involves setpoint operations, such as auto modes,
auto gas changeover, etc. See Table 12 for an operational example.
Inside Temperature ( ° F)| Heating Setpoint ( ° F)|
Heating Hysteresis ( ° F)| System Operation
---|---|---|---
69| 68| 3| None
66| None
65| Heating Cycle Begins
67| Heating Cycle Continues
69| Heating Cycle Terminates
Measurement Units
This setting determines how to display temperatures on the thermostat. Tap the
Units button to toggle between Fahrenheit and Celsius.
Touchscreen Calibration
The EasyTouch RV touchscreen is calibrated at the factory to accurately
interpret your touch presses. Pressing the Touchscreen Calibrate Button will
allow you to recalibrate the touch press area. Follow the on-screen prompts to
calibrate the touchscreen.
Restart
This setting will turn the thermostat off then on as if removing and restoring
power. Tap the Restart button and follow the on-screen prompts to confirm.
Reset All
This setting will reset certain settings in the thermostat back to factory
defaults. Some thermostats offer options to which settings to return to
defaults. Tap the Reset All button and follow the on-screen prompts to choose
what you would like to reset.
Setup
This setting is used to configure your thermostat’s operational settings and
is slightly different for each EasyTouch RV model. Some simply display how the
air conditioner control board that EasyTouch RV communicates with is
configured. Others allow for telling EasyTouch RV what appliances it has
connected to it. Tap the Switches button to see what configurations are
available. See section Initial Setup Instructions for details on what must be
configured, if any. Micro-Air cannot assist with manipulating and adding more
appliances to your system.
Auto-Generator Start (AGS)
Warning: See Section Configure Auto-Gen Start in Initial Setup
Instructions to configure this behavior where appropriate.
This setting allows for a generator to start prior to any appliances that need line voltage to run. EasyTouch RV will output voltage to its pin 3 grey wire to go to existing AGS hardware, prior to calling for any appropriate cycles. It then disconnects voltage from this wire when it is no longer needed. Tap the AGS Enable button to green to enable this behavior or to gray to disable it.
Furnace/Aqua Icons
Most RV systems have auxiliary heat modes in the form of a “forced-air” gas
furnace or hydronic heat. EasyTouch RV or the associated control board treats
these as the same output and so you can tap the Furnace/Aqua button to toggle
between what icons to display for this operational mode. This is simply a
cosmetic setting for all EasyTouch RV models except the 350 model, which
should be set appropriately.
Schedule Screens
The schedule supports 7 day per week scheduling of events. Events can include
changes to the set point or mode of operation for one or more zones. Each
numbered row is an event that can be configured.
Figure 8 shows the main schedule screen. Tap the “Schedule” button from the
Settings Screens to enter.
The smart device application also offers a method to copy days. Once a
schedule is set for one day, it can be copied to any other day.

Smart-Device Application Features
Restart Thermostat
This Bluetooth only feature allows resetting the display just as if you removed and restored power.
Check for Updates
Checks to see if any updates are available for the thermostat. The smart device application must have internet and the thermostat must be connected to Wi-Fi with a green Wi-Fi symbol. Tap Check for Updates and follow the prompts.
Note: Beta updates may be available from time to time, but these are for people working with Micro-Air in testing them. Some features may not work as expected. The current version firmware can be restored by checking for updates again.
Notifications
Notifications provide a way for the user to monitor the temperature in the space using notification limits. Limits are set by connecting to the thermostat in the app, selecting the settings gear, and then selecting notifications. A minimum and maximum allowed temperature can be set. Table 13 shows an example of operation with an 80°F maximum temperature set.
A Notification will be sent for each degree it rises above the maximum temperature. If temperature drops, no notification will be sent unless the temperature exceeds the last maximum temperature again (82 in the example). If the temperature drops two degrees below the set maximum, (78 in the example) it will again alert for each degree above the set maximum. This behavior helps avoid nuisance notifications to your smart device. The same occurs in the opposite direction for the lower limit.
Table 13 – Push Notifications Operation Example
Temperature (°F) | Action |
---|---|
80 | Send first notification |
81 | Send another notification |
82 | Send another notification |
81…79 | Temperature drops, no notification |
78 | Max temp resets |
Edit Wi-Fi Settings or Connect to Wi-Fi
This is where you will make the connection from the thermostat to the
internet. See section Connecting to a New Wi-Fi Network for details on how to
use this feature. The app must be connected to the thermostat over Bluetooth
to see this option.
Refresh Configuration:
This is a temporary feature that resets the saved configuration on the phone
if a configuration change is made at the thermostat, for example, enabling the
heat pump mode for a zone from the Setup Settings Screens. This will be
removed later. If you experience a difference between the app modes available
and the thermostat modes available, then press this button to fix the issue.
Appendix A: Working Wirelessly
This thermostat may be operated remotely using either Bluetooth or Wi-Fi. All connectivity is performed through the EasyTouch RV App on a smart device. The app is downloaded from the Google Play store or Apple App store. The first time the app is opened, it will ask to create an account. Create your account and follow the prompts to connect your thermostat.
Bluetooth is a limited range method to connect, typically used when near the
thermostat.
The thermostat can be connected to an internet-connected network, where you
can then access the thermostat from anywhere you have an internet connection
with the app.
If a second user is going to use the thermostat remotely, they MUST use the same account and password that the first user assigned to the thermostat. Each thermostat can only be assigned to a single account, but many users can control the thermostat if they use the same account.
First Connection Steps
Note: An internet connection on your smart device is necessary for these steps.
-
EasyTouch RV uses BLE which is a special implementation of Bluetooth. The smart device and thermostat do not “Pair” like other common devices. Ensure that Bluetooth is enabled in the smart device settings, and that the app has Bluetooth permissions. Android systems have changed over time and some users may need to have location permissions give to the app, location permissions turned on in general, our give “nearby devices” permissions to the app.
-
Start the app on your smart device. Bluetooth permissions must be accepted and may prompt you for them. The app will open to a main page where you can log-in, delete an account, recover a lost password, or create an account. Tap create account and enter your name, email, and a password at the prompts. The system will send a confirmation email to your inbox. Enter the number in the confirmation email when asked.
-
Once the account is created, the application may ask to add a device. If your thermostat is powered and permissions are set up, it will show in the list to be added to your account, found over Bluetooth.
Select the device and enter a name for it. This name is used to identify and connect to it in the future. -
If you added a control, the app will ask if you want to connect the thermostat to Wi-Fi now. Enter your SSID (network name) and password of the network you want to connect the thermostat to.
Adding a Thermostat to Your Account
Follow the next steps if the account process does not add a control or a second thermostat is to be added.
- Open the app and you should be signed in from the directions of the First Connection Steps section. Press the settings gear and “Add Device”.
- The nearby thermostat(s) should be listed in the “Devices Found” list. These are the thermostats heard over Bluetooth. Select the device and enter a name for the device.
- Once added, go back to the “Devices” screen, which lists all the thermostats added to your account.
- Select the thermostat you want to control from the “Devices” list to connect.
Connecting to a New Wi-Fi Network
You can connect to the thermostat from anywhere using the app when the
thermostat is connected to
an internet source. The internet source must be operating on a 2.4GHz network
to connect to EasyTouch.
-
Connect to the thermostat in Bluetooth and press the settings gear. Apple users select Bluetooth on the first page.
-
Select “Connect to Wi-Fi” or similar from the settings window.
-
Connect to a network:
a. The SSID (network name) will say “searching” then switch to “select”. Tap “select” to choose from a network the thermostat can hear.
i. Alternatively, enter the SSID manually (case sensitive)
b. Enter the password (case sensitive). -
Press OK and the screen will return to the selection screen. The thermostat will reset and a green Wi-Fi symbol will appear on the main thermostat screen if the connection was successful.
-
With a green Wi-Fi symbol, you can now connect to the thermostat from anywhere using the app over the internet.
Updating The EasyTouch RV Thermostat
Ensuring you have the latest thermostat software is key to having all the
latest features.
- Ensure the thermostat is connected to Wi-Fi with a green Wi-Fi symbol.
- Connect to the thermostat and press the settings gear, then tap Check for Updates.
- Follow the prompts to update the thermostat or ensure that you already have the latest software
Appendix B: Troubleshooting
The most common problems during installation are not matching the wires
correctly or properly
mating the wires. The first step should always be to recheck the instructions
and make sure the wires are joined and seated properly.
The second most common problem is not knowing the thermostat operation. If the system is running a heating or cooling cycle, the set point will turn red for heating and blue for cooling. When the thermostat turns white, the heat pump, heat strip and furnace should all be off. The fan may continue to run for a while after the cycle completes. If a fan is left in a manual mode it will not shut off.
Testing an Output
Table 4 – Wire Color Chart in section Wiring the Thermostat shows the
color label and purpose for each of the thermostat wires. This information can
be used in troubleshooting to verify that the thermostat has turned on an
output when expected.
You can use a voltmeter to verify that the thermostat has turned on an
EasyTouch output. Set to voltmeter measure DC voltage and check for ~12 volts
between the blue (ground) wire and the output terminal to be tested to see if
the thermostat has turned on the output. If there is 12 volts present further
troubleshooting of the component (fan, compressor furnace, heat pump, heat
strip) is required. If 12 volts is not present, verify that the fuse in
EasyTouch RV is still good and the thermostat should be calling for that
output.
Wi-Fi Troubleshooting
Blue Wi-Fi Icon – No connection
- SSID (Network name) and password are both case sensitive.
- Be sure you are connecting to a 2.4 GHz network and not a 5GHz or 6GHz network.
- Set the security to WPA2 and TKIP+AES if you are having trouble.
- The thermostat has a limit of 31 characters for the SSID and 50 for the password.
- Ensure the number of devices limit for the network is not full.
- Ensure the Wi-Fi source is not out of range or metal partitions blocking the signal.
- Try a guest network or mobile hotspot that may have reduced restrictions.
- Reset the router to renew the DHCP lease.
- If you are in a metal enclosure, try moving the router or thermostat a few inches (even if temporary) and trying again.
- If using MAC filtering, add the thermostat to the allowed devices list.
- Try assigning a DHCP reservation to the thermostat MAC address.
Red Wi-Fi Icon – Connected without Internet
- The router must have an internet connection
- Server may be down, check back at a later time
- Be sure there is no firewall in the router blocking the incoming messages (port 8883, MQTT). Place the thermostat IP into the DMZ settings to bypass any firewalls.
