The EasyTouch 359 model 12-volt thermostats were designed to directly replace the Dometic™ model 3106995 single zone DC 7.5-volt thermostats. The thermostats can be used in other applications with certain electrical limitations as explained later in this document.

Safety First

Turn off power to the air conditioner breaker and to the 12-volt circuit powering the thermostat. There is always a risk of shock in any system that is connected to high voltage utility power so removing power greatly reduces that risk.
There is a risk of creating a short circuit with some of the thermostat wires during installation that can cause a failure or undesired operation. Removing power reduces the risk you will damage something or open a hard-to-find fuse during installation.

Installing the thermostat

There are four steps to installing the thermostat. Removing the thermostat, wiring the new thermostat, installing the new thermostat, and finally, updating the control box wiring. Please read each section entirely before proceeding with that section. Please perform these steps in order otherwise you may damage your original thermostat.
Removing the old thermostat
IMPORTANT: Take a picture of the wires and labeling so if there are any questions about the original configuration later, you can see how it was connected.
Remove the front cover by carefully popping it off. Complete Table 1 using your wire colors. Your colors may be different from the normal factory- suggested wire colors and not all wires may be used. Label any that are not there with “Not used”.
Table 1

Typical original thermostat wire
color| Original factory wire harness color (Write in here)| Connect to EasyTouch
terminal label| Function
---|---|---|---
Red or Red/White| | R| +7.VDC
Black or Green| | B| -Ground
Orange or Tan| | GL| Fan
Green| | GH| Fan high
Yellow| | Y| Cool
Violet or Orange| | WHP| HP (heat pump)
White| | W| Furnace
Not used| | SEN| Sensor
Not used| | SEN| Sensor

Disconnect the red or red/white wire labeled +7.5V and place a piece of tape around the exposed wire end. Disconnect the remaining wires (tape is not necessary). Remove the cover to expose the two screws that hold the thermostat to the wall and remove the rest of the thermostat.
Using the push button terminals
Figure 1 shows a screwdriver depressing the push button connector. The silver gate is opened for the wire to be inserted. Releasing the button traps the wire and makes the connection.  Remove approximately 3/8 inch (1cm) of insulation from the wire to be inserted. Use a small screwdriver (not provided) or similar tool to push down on the square push button. Insert the wire in the insertion space and release the push button. Verify the connection by gently pulling on the wire. Do not force excessive wire down into the connector. If the stripped wire end is longer than 3/8 inch, cut the end so there is no bare wire sticking out when properly inserted. Wiring the thermostat
SAFETY FIRST: Turn off power to the air conditioner breaker and to the 12-volt circuit powering the thermostat. There is always a risk of shock in any system that is connected to high voltage utility power so removing power greatly reduces that risk and the risk of shorts that can damage something. Use the table entries written in Table 1 to complete the wiring. Insert each wire as described in the section titled “Using the push button terminals”. Insert the +7.5-volt wire last so it cannot contact any other wires
when the tape is removed.
Change the control box wiring
SAFETY FIRST: Remove power before changing the control box wiring.
Step 1: After removing power from the AC unit, remove the ceiling vent as shown in Figure 2. Identify the red and red/white wires exiting the control box near the area indicated by the blue arrow. These wires are pulled out and shown in Figure 3 connected to a brown and thin red wire. They may still have labels on them to indicate their
function.  Step 2: Remove the wire connected to the red/white wire which may still have the label “To TStat 7.5 Screw”. Put a connector over the red wire with stripe as shown in Figure 3. Step 3: Add the wire disconnected in step 2 to the +12-volt wire connections as shown. This installation uses wire nut electrical connectors. However, crimp splice or WAGO connectors are more desirable for the vibrations encountered by the terminals.
My wire colors and gauges are different than shown?
There will be 4 wires of varying thickness and color between red, red/white, and brown, configured in two pairs. The goal is to identify which of these 4 wires goes to the original thermostat’s +7.5 terminal (one of the red or red/white wires) and move it to the other pair. This will route 12 volts down to EasyTouch. You should have ultimately a wire by itself (the control box outgoing +7.5 wire) and the other three altogether (incoming +12, input +12 for the control box, and now the outgoing thermostat red or red/white wire).

Mounting the thermostat

Step 1: Locate the mounting buttons horizontally across the hole with a smaller diameter against the wall.

Step 2: Screw in one screw and level the buttons so the display will be straight when installed.

Step 3: Screw in the second screw making sure the two buttons remain level.

Step 4: Remove the mounting tab before mounting on the wall. Step 5: Align 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.

Gas Heat Override Enable/Disable
You can enable or disable gas heat override by tapping the Enable/Disable button under the “Auto Gas Changeover” heading. When enabled, all of your available heat modes will act in stages based on how far the inside temperature is from the set point. See section Gas Heat Override for more details. Most users will leave this setting enabled. Invert On/Off
This setting changes the polarity of the furnace from +12 volt active to ground active. Most users will set it for invert ON. Setting the incorrect setting will cause the furnace to operate all the time.
Connecting remotely
EasyTouch RV can be operated entirely by the touchscreen, however, you can also communicate, monitor, and modify its operation of it wirelessly using the EasyTouch RV application. Some extra features will require a wireless connection and is described in their sections. See section Working Wirelessly for details.

Operating the Thermostat

Main Screen
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 4.

1. Inside temperature
   This is the temperature reading for the space that the thermostat is trying to temper, determined by a local sensor. “Inside” means it is using a sensor inside the thermostat. “Inside(R)” is not used in this model and should display “Inside”.

2. Local Weather
   This icon indicates the local weather at the last time weather information was received. Tap the icon for more detailed weather information. See section Local Weather and Local Time for more details.

3. Status Tray
   Various icons may be here to indicate active operations.
   The Wi-Fi indicator shows the state of the thermostat’s Wi-Fi connection. No icon means no connection to an internet-enabled device. Red means it is connected to an internet-enabled device but does not have internet. Green means it is connected to the internet. The number of bars indicates strength. See the Connecting to a New Wi-Fi Network for more details. The Furnace icon here means that the heat mode is in Gas Heat Override. See section Gas Heat Override for more details. The Schedule icon here means that the created schedule is active and will change operation on that schedule. This is turned on and off in the Settings screens. See section schedule Screens for more details.

4. Status Message
   Various messages may be shown here to indicate active operations. See the Status Messages section for potential messages and their meanings.

5. Temperature Set Point Adjust
   Raise and lower the temperature set-point using the red and blue arrows. This sets the desired temperature for the space based on the operating mode. All modes are listed in the (7) Operational Mode section.

6. System Power
   Use the power button to turn the system on or off. The button is red for off and green for on.

7. Operational Mode
   Pressing the mode button changes the current operating mode depending on what is available in your system. All possible modes are listed below. See the Operational Modes section for more details.
   Note: If you do not see a mode you should then see the section Setting the Available Sources.

8. Fan Speed
   Pressing the fan button selects how the fan will operate in conjunction with the (7) Operational Mode. Fans with green bars are manually always-on regardless of heating or cooling, with a number of bars indicating speed. Fan Auto turns the fan on and off with a cooling or heat pump/strip cycle, and operates as Fan Off in all other operational modes. Fan Auto will switch from low to high speed automatically based on the difference between inside temperature and setpoint. See section Temperature Gap (Hysteresis) for details on controlling when this occurs. If Fan Auto determines that high speed is needed then it will remain on high until the cycle terminates.![micro Air ASY 354 X02 C Inverter Supply - terminatesmicro Air ASY 354 X02 C Inverter Supply

  9. Settings
     Pressing the settings button will change the screen to the settings screen to allow additional configurations. See section Settings Screens for more details.

  10. Additional Status Tray
      Various icons may be here to indicate active operations. The hourglass symbol indicates that a heating or cooling cycle delay is in progress. It is an indication that the thermostat will start a cycle soon. This is a 3-minute timer from the end of a previous cycle to prevent a new cycle from occurring.

  11. 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 (2) Local Weather information.

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 (8) 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 (7) Operational Mode button to Cool Only and the desired (8) Fan Speed, where behavior will then be based on Table 2.

on Gap
Inside Returns 1° Below Setpoint| Cooling Cycle Terminates| Runs 30 More Seconds, Off

Note: Table 2 operation may be different based on the Gap settings. See section Temperature Gap (Hysteresis) for details.
Heat Pump Only and Heat Strip Only Mode  This mode only runs an electric, overhead, heat pump or heat strip heating cycle to maintain the heating set- point in the space. Set the (7) Operational Mode button to Heat Pump Only or Heat Strip Only and the desired (8) Fan Speed, where behavior will then be based on Table 3.

Based on Gap
Inside Returns 1° Above Setpoint| “Electric” Heat Cycle Terminates| Runs 30/90 More Seconds, Off

Table 3 – Heat Pump and Heat Strip Only Mode Operation
Note: Table 3 operation may be different based on the Gap settings. See section Temperature Gap (Hysteresis) for details.
Note: These heat modes are subject to Gas Heat Override Operation when enabled. See section Gas Heat Override for details.
Furnace Only or Aqua Only Mode
This mode only runs an auxiliary heating cycle to maintain the heating set- point in the space. Set the (7) Operational Mode button to Furnace Only or Aqua Only and the desired (8) Fan Speed, where behavior will then be based on Table 4. See section Furnace/Aqua Icons for details on the auxiliary heating icon.

Table 4 – Furnace Only Mode Operation
Note: Table 4 operation may be different based on the Gap settings. See section Temperature Gap (Hysteresis) 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 set- points.

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. Figure 5 shows how the main screen will look in auto mode.
Note: These auto modes are subject to Gas Heat Override and Gap operations. See their Gas Heat Override and Temperature Gap (Hysteresis) sections respectively for more details.

(1) Auto Mode Set-Points
Press the set-points to toggle between which set-point you have selected. A blue square will show around the one you have selected. The upper set-point is for cooling and the
lower set-point is for heating.
(2) Set-Point Adjustment
Use the up and down arrows to change the selected set-point value.
Gas Heat Override
Note: See section Gas Heat Override Enable/Disable for enabling and disabling this feature. Gas Heat Override operation is an algorithm for calling for additional stages of heat when the thermostat determines more are needed. The two escalating stages are shown in Table 5. This logic is disabled when both stages are not available.

Table 5 – Heat Staging

Table 6 shows how Gas Heat Override affects the heat pump and heat strip operational modes when enabled. This applies to heating cycle calls in auto operational modes as well.

Note: Table 6 operation may be different based on the Gap settings. See section Temperature Gap (Hysteresis) for details.
Local Weather and Local Time
Local weather is displayed on the main screen and shown visibly in section (2) Local Weather under section Main Screen. Tapping the button will reveal more detailed weather information of the last received weather data. The local temperature is displayed in the lower-left corner of the main screen, as shown in section (11) Outside Temperature. 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. The location in the thermostat is updated when a subsequent Bluetooth connection is made with a different smart-device location than the one saved. Location is preserved through power losses or device restarts.
New weather data is retrieved when there is a 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 re-established, without app interaction.
Status Messages Some messages may be displayed on the main screen as shown in section (4) Status Message under Main Screen. Table 7 shows the potential messages and their meaning.

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 the section Connecting to a New Wi-Fi Network for more details about using Wi-Fi.

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)
These settings under “heat” and “cool” headings determine the difference in temperature required between setpoint and inside temperature before 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, gas heat override, etc. See Table 8 for an operational example.

Inside Temperature (°F)| Heating Setpoint (°F)| Heating Gap
Setting (°F)| System Operation
---|---|---|---
69| 68| 3| None
66| None
65| Heating Cycle Begins
67| Heating Cycle Continues
69| Heating Cycle Terminates

Table 8 – Temperature Gap Operational Example

The setting “Auto-Fan High” determines the difference in temperature required between setpoint and inside temperature for the Auto Fan (8) Fan Speed to switch from Fan Low to Fan High. If Fan High is called for during a cycle then it will remain high until the cycle terminates. See Table 9 for an operational example where the “Cool Gap Setting” is 1°F.

Inside Temperature (°F)| Cooling Setpoint (°F)| Auto Fan Gap
Setting (°F)| System Operation with
Auto Fan
---|---|---|---
81| 78| 4| Cooling with Fan Low
82| Cooling with Fan High
79| Cooling with Fan High

Table 9 – Auto Fan Speed Gap Operational Example
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. Any overlapping test targets on the second screen is a good calibration.

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.

Dip Switches
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 Thermostat Setup 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)
This setting allows for a generator to start prior to any appliances that need line voltage to run, then turns it off when the cycle completes. 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 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.

Smart device settings options

Reset device
This Bluetooth-only feature allows resetting the display just as if you removed and restored power.
Calibrate Touchscreen
It is normally not necessary to recalibrate the touchscreen. This selection prompts the user to press the four corners of the display and then test the calibration using three diagonal marks. This feature is only available from Bluetooth as being at the thermostat is required.
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.
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 10 shows an example of an operation with an 80°F maximum temperature set. A notification will be sent for each degree it rises above the maximum temperature. If the 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.

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 Connect 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.

Troubleshooting

The most common problems during installation are mismatching the wires and not seating the wires in the connector properly. The first step should always be to recheck the instructions and make sure the wires are seated properly.
The second most common problem is not knowing the thermostat operation. If the system is running a heating or cooling cycle, a large number of the temperature set point will turn red for heating and blue for cooling. When the large thermostat numbers turn 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 manual mode, it will not shut off.
Testing an output
The first step is to check the fuse on the back of EasyTouch and verify it is still good.
Figure 5 is a table showing the terminal label and purpose for each of the thermostat wires. This information can be used in troubleshooting to verify that the thermostat turned on an output. Use a voltmeter to verify that the thermostat has turned on an EasyTouch output. Set to voltmeter measure DCvoltage and check for ~0 volts between the blue (ground) wire and the output terminal to be tested to see if the thermostat has turned on the output. There should be 0 volts present when the output is on and 12 volts when the output is off. Further troubleshooting of the component (fan, compressor furnace, heat pump, heat strip) is required if the voltages are correct but the output is still not operating. If the thermostat does not have power, test between the R and B wires to determine if there is 12-volt power to the thermostat.

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.

1. EasyTouch RV uses BLE which is a special implementation of Bluetooth. It is not necessary to “Pair” the thermostat with the phone but an account must be created for operation. Ensure that Bluetooth is enabled and that the app has Bluetooth and location services permissions. Android users must also have location services turned on in general.
2. Start the app on your smart device. The app will open and if you have not entered your account information, it will ask you to create an account and enable permissions. Enter your name, email, and password at the prompts. The system will send a confirmation email to your inbox. Enter the number in the confirmation email when asked.
3. Once the account is created, the application may ask to add a device. If your thermostat is powered it will show in the list to be added to your account. Select the device and enter a name for it. This name is used to identify and connect to it in the future.
4. If you added control, the app will ask if you want to connect it 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 accounting process does not add a control or a second thermostat is to be added.

1. Press the settings gear and “Add Device”.
2. The nearby thermostat(s) should be listed in the new selection window. These are the thermostats heard over Bluetooth. Select the device and enter a name for the device.
3. Press OK and the screen will return to the settings menu (Android) or the selection screen (Apple). Android users should press the back button to get to the selection screen.
4. Select the device name to open the thermostat screen.

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 a 2.4GHz network to connect to EasyTouch.

1. Connect to the thermostat in Bluetooth (Apple) and press the settings gear.

2. Select Wi-Fi Setup from the settings window.

3. 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).

4. 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 thermostat screen if the connection was successful.

5. With a green Wi-Fi symbol, you can now connect to the thermostat from anywhere using the app over the internet
