• close to or in direct airflow from supply registers or return
air grilles
• in areas with poor air circulation (such as behind a door or
in an alcove)
Mount Transmitter (Optional)
IMPORTANT: If the transmitter is replacing an existing
thermostat and will be mounted in the same location, the
wiring from the unit must be run to a different location
where the receiver is mounted. The transmitter is NOT wired
to the unit. The receiver is wired to the unit and processes
the signals received from the transmitter.
1. If an existing thermostat is being replaced:
a. Remove existing thermostat from the wall.
b. Disconnect wires from existing thermostat. Remove
wiring.
c. Discard or recycle old thermostat.
NOTE: Mercury is a hazardous waste and must be
disposed of properly.
2. Remove the transmitter cover from wall plate (mount-
ing base) to expose mounting holes. See Fig. 1.
3. Level mounting base against wall and mark wall through
the 2 mounting holes in base.
4. Drill two

-in. mounting holes in wall where marked.
Be careful not to drill into wiring in wall. Electri-
cal shock could result.
5. Secure mounting base to wall with 2 screws and an-
chors provided.
6. Seal hole in wall to prevent drafts.
7. Re-attach transmitter cover to back plate.
Set Clock — The user can change the time and day dis-
played on the transmitter. Press and hold the Mode and Over-
ride buttons simultaneously for at least 2 seconds. The trans-
mitter will be in Set Clock mode. The display will show the
Set Up annunciator. The number of the Set Up step is shown
in the upper right corner. The current time will blink on and
off. Current Time is Set Up Step 1. Press the UP ARROW
and DOWNARROW buttons until the correct time is shown.
Hold down the buttons to quickly move through the time
display. The AM and PM annunciators will automatically
change. To ensure the schedules are properly followed, make
sure that AM or PM is correct for the time chosen. Hold
down the Override button while pressing the UP or DOWN
ARROW buttons to scroll through by hours instead of min-
utes. When the correct time is shown, press the Mode button
to modify the day of the week. The current day will blink on
and off. The Day of the Week is Set Up Step 2. Press the UP
ARROW and DOWN ARROW buttons until the correct day
is shown. Press and hold the Mode and Override buttons again
for 2 seconds to exit the Set Clock mode. If no button is
pressed for 60 seconds, the display will automatically return
to normal operation.
ConfigureAdvanced Set Up — To enter into the ad-
vanced set up screens of the transmitter, press and hold the
Mode and Override buttons for at least 5 seconds. The set up
step number is shown in the top right corner of the trans-
mitter screen. Use the Mode button to advance through the
steps. See Table 1. Press the Mode and Override buttons at
the same time to exit the Advanced Set Up mode. If no but-
ton is pressed for 60 seconds, the display will automatically
return to normal operation.
NOTE: See Set Clock section above for information on Ad-
vanced Set Up steps 1 and 2.
ZONING SYSTEM (Step 3) — The Zoning System con-
figuration configures the thermostat for use in a zoning sys-
tem. If the thermostat is being used in a zoning system, set
the configuration to YES. If the thermostat is not being used
in zoning system, set the configuration to NO. The default
is NO.
HOUSE CODE (Step 4) — The house code is used by the
transmitter and receiver to identify that they are used to-
gether. If more than one transmitter is used, all transmitters
must have the same house code number as the receiver. If
separate receivers and transmitters for different equipment
are used near each other, they should be configured with dif-
ferent house codes. The default is 0. The range is 0 to 63.
NOTE: More than one receiver can be used on jobs where
the furnace and air conditioner are not wired together. Two
separate receivers can be used with one wired to the furnace
and one wired to the air conditioner, which can both be con-
trolled by the same transmitter. These receivers must have
the same house code.
UNIT ID NUMBER (Step 5) — The unit ID number is used
when more than one transmitter is used with a receiver. When
more than one transmitter is used with a receiver, each trans-
mitter must be given a different unit ID number. This allows
the receiver to keep track of which transmitter sent the last
command. This transmitter will control the unit until a dif-
ferent transmitter sends a command to the receiver. The de-
fault is 1. The range is 1 to 4.
NOTE: Advanced Configuration steps 6, 7, 9, 11 are
only available for transmitters configured with Unit ID Num-
ber 1.
FAN MODE (Step 6) — The fan mode is used to configure
fan operation. If Fan On is selected, the fan will run con-
tinuously during the Occupied schedule (except when Mode
is switched to OFF). The fan will be off during unoccupied
schedule except during heating or cooling operation.
If Auto is selected, the fan will operate only during heat-
ing or cooling operation. The default is Auto.
DEADBAND (Step 7) — The Deadband is the difference in
temperature above the cooling set point or below the heating
set point that the thermostat will wait before turning on the
first stage of heating or cooling. For example, if the cooling
set point is 82 F and the deadband is 2 degrees F, the first
stage of cooling will not be energized until the temperature
reaches 84 F. The range of values is 1 to 6 degrees. The de-
fault is 2.
