Wall Locations The thermostat should be installed approximately 4 to 5 feet above the floor. Select an area with average temperature and good air circulation.
Installation Tip
Pick an installation location that is easy for the user to access. The
temperature of the location should be representative of the building.
Do not install thermostat in locations:
· Close to hot or cold air ducts · That are in direct sunlight · With an
outside wall behind
the thermostat · In areas that do not require
conditioning · Where there are dead spots
or drafts (in corners or behind doors) · Where there might be concealed
chimneys or pipes

Battery installation is
optional if thermostat is
hardwired (R and C terminal

Important:
High quality alkaline batteries are recommended. Rechargeable batteries or low
quality batteries do not guarantee a 1-year life span.
Insert 2 AA Alkaline batteries (included). High quality alkaline batteries are
recommended.

Base Module Mounting Tips
Base Module – PTAC Installation Range between the thermostat and the base
module is up to 100 feet with no obstructions and up to 50 feet through
standard building materials. To optimize the range try placing the base module
with no metal between it and the thermostat. The base module is designed to be
mounted behind the front grille of a packaged terminal air conditioner (PTAC).
Refer to the PTAC manufacturer’s manual for instruction to remove the front
grille. Check clearance to ensure the fit of front grille after base module
installation. See below for a few location recommendations.

1 Ambient Temperature: Displays the current room temperature

3 Staging Indicaators:
If these or the fan indicators are flashing, it means that the system is in a
delay of some type (compressor delay, cooling fan delay, or staging delay) or
a pending change.
Energy Efficient Globe: Indicates you are making an energy efficient set at
temperature. Wireless Symbol: Indicates you have a wireless connection.
Low Battery Indicator: Replace batteries when this indicator appears.
Important
The low battery indicator is displayed when the AA battery power is low. If
the user fails to replace the battery within 21 days, the screen will only
show the low battery indicator but maintain all functionality. If the user
fails to replace the batteries after an additional 21 days (days 22-42 since
first “low battery” display) the setpoints will change to 55°F (Heating) and
85°F (Cooling). If the user adjusts the setpoint away from either of these, it
will hold for 4 hours then return to either 55°F or 85°F. After day 63 the
batteries must be replaced immediately to avoid freezing or overheating
because the thermostat will shut the unit off until the batteries are changed.

Front Mount: Inside PTAC Housing
Base Module Mounting Tips
When Working With A Vertical Unit 1. Do not mount Module inside the cabinet of
the unit, or in a metal enclosure. 2. Mount on the outside of the unit to
maximize wireless communication.
Caution: Electrical Hazard
Failure to disconnect the power before beginning to install this product can
cause electrical shock or equipment damage.
When Working With A Metal Sleeve Cabinet, Room Cabinet, or PTAC Cover
1. If cabinet has open bottom, mount the module just inside the cabinet as
close to the open bottom as possible without placing it in danger of being
bumped or touched by furnishings, vaccum, etc. 2. Another good module location
would be on the underside of the top of the cabinet or cover. Directly behind
the open Louver/Grill.

Wiring
1. If you are replacing a thermostat, make note of the terminal connections
on the thermostat that is being replaced. In some cases the wiring connections
will not be color coded. For example, the green wire may not be connected to
the G terminal.
2. Loosen the terminal block screws. Insert wires then retighten terminal
block screws.
3. Place nonflammable insulation into wall opening to prevent drafts.

Thermostat Wiring Tips
C Terminal The C (common wire) terminal does not have to be connected when the
thermostat is powered by batteries.
Wire Specifications
Use shielded or non-shielded 18-22 gauge thermostat wire.
Note: The base module may be mounted using adhesive tape, such as double-sided tape or hook and loop strips. The base module must be hardwired (C & R terminals connected to 24V power). Use secondary source of securement to prevent module from dropping into condenser drain pan. Connecting to a PTAC: When connecting the Base Module to a PTAC, refer to the PTAC manufacturer instructions to enable remote thermostat operation.
Note:
Most PTAC systems support two speed fan operation. In a single speed fan PTAC
system or conventional single speed fan system, the GL terminal will be used
and “I” must be selected in the Technician Setup Menu.
Power supply
The thermostat must be set to O or B to match the changeover valve, O is the
cool changeover valve, B is the heat chageover valve.
The Aux. Heat Relay is energized as the second stage of heat.

Establishing A Connection
Establishing Communication between the thermostat & the base module
The Thermostat and Base module in this package are linked at our factory. Upon
power up they will automatically begin communicating. If you wish to make any
changes to the network such as adding or removing devices, please follow the
instructions on this page.
How To Pair
On the Base module:
1. Press the button next to the LED. 2. The Base module will begin double
blinking pink for 2 minutes while it waits
for a remote to join. 3. Once a device joins, the LED will show green blinks
and return to
normal operating mode.
On the Thermostat:
1. Press and hold the light button for 3 seconds. The LED will flash 3 times
and pair with the base module.
2. The Thermostat will attempt to connect to a Base module within range 3.
Once paired, the LCD will temporarilly display “PAIRED” when it joins with
a Base module.
How To Unpair
On the Base Module:
1. PRESS and HOLD the button next to the LED for 6 seconds. 2. The Base
module LED will turn RED for 6 seconds. 3. All connected devices will be
deleted.
On the Thermostat:
1. Enter the “UNPAIRING” tech menu. 2. Press and hold the “+” button. 3. The
LCD will show “UNPAIRED”. 4. The Thermostat will no longer be connected to a
network.

Base Module LED Information
The Base module’s LED is used to communicate the status of the wireless
network. · Green Blink at 3s: Normal operating mode. All devices are connected
and healthy. · Yellow Blink at 3s: Normal operating mode. One or more (but not
all)
remote devices are NOT reporting. · Red Blink at 3s: Normal operating mode.
ALL network devices are
NOT reporting. · White Blink at 3s: Unpaired mode. Base module is powered but
is NOT
paired to any remotes. · Blue double blink: Transmission received from a
remote. · Purple double blink: Base module is in pairing mode waiting for a
remote. · Green 5 quick blinks: A remote has successfully been added to the
basemodules network.
Note:
This equipment has been tested and found to comply with the limits for a Class
B digital device, pursuant to part 15 of the FCC Rules. These limits are
designed to provide reasonable protection against harmful interference in a
residential installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular
installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and
on, the user is encouraged to try to correct the interference by one or more
of the following measures: · Reorient or relocate the receiving antenna. ·
Increase the separation between the equipment and receiver. · Connect the
equipment into an outlet on a circuit different from that to
which the receiver is connected. · Consult the dealer or an experienced
radio/TV technician for help.

the Base module while pairing. Once paired, the signal strength tech menu can
be used to ensure a robust wireless connection. · Placing either device in or
