NOTE: Occupied 1 schedule heating and cooling set points
are the same for each day. Occupied 2 and 3 set points
may be set to different values for each day of the week.
If YES was selected, the schedule will be copied to the
next day. The schedule copy may be repeated until Sun-
day is reached. The Sunday schedule cannot be copied
to Monday.
12. After all the times and set points for each day have been
entered, press and hold the Mode and UP ARROW but-
tons for 2 seconds to exit Programming mode.
NOTE: The thermostat will continue to follow the schedule
until a new one is entered.
If only one occupied schedule is selected, the Occupied 2
and 3 schedules are skipped. If the start time is set later in
the day than the stop time, the program will run from mid-
night of that day to the stop time and then from the start time
to midnight. If the same start and stop times are pro-
grammed for an occupancy schedule, the thermostat will be
in Occupied mode for 24 hours. If one occupied period starts
or stops within another occupied period, the lower num-
bered schedule has priority. For example, if schedule Oc-
cupied 3 is running for 24 hours and Occupied 2 schedule
comes on from 1 to 3 PM, the set points from Occupied 2
are in effect from 1 to 3 PM.
OVERRIDING THE SCHEDULE — The schedule can be
overridden by pressing the UP or DOWN ARROW buttons
to change the desired temperature. The thermostat will use
the new set point until the next scheduled time period starts.
Calibration — Every transmitter temperature sensor is
factory calibrated. Under normal circumstances there will never
be a need to re-calibrate the sensor. If re-calibration must be
done, perform the following procedure:
1. Hold down the Mode button and press the DOWN
ARROW button simultaneously for 2 seconds. All of the
icons on the display screen will appear. Release the
buttons.
2. Press the Mode button. The current temperature will be
displayed.
3. Use an accurate thermometer to measure room tempera-
ture. Press the UP or DOWN ARROW buttons until the
displayed temperature equals room temperature.
4. Press the Mode button to return to normal operation.
Check Thermostat Operation — To check thermo-
stat operation, perform the following procedure:
1. Press the Mode button repeatedly until the Heat icon ap-
pears on the display. The thermostat is now in Heating
mode.
2. Press the UP ARROW button until the heating set point
is 10 F (6 C) higher than the current room temperature.
Heating and fan should be energized.
3. Press the Mode button repeatedly until the Cool icon ap-
pears on the display. The thermostat is now in Cooling
mode.
4. Press the DOWN ARROW button until the cooling set
point is 10 F lower than the current room temperature.
Cooling and fan should be energized.
5. If heating, cooling, or fan operations do not energize, check
wiring and consult Troubleshooting section.
Final Checklist
1. Put away tools and instruments. Clean up debris and
packaging.
2. Review Owner’s Guide with occupant or owner.
3. Leave the manuals with owner.
OPERATION
The Mode button selects the operating mode of the ther-
mostat. If OFF is selected, the thermostat will not enter Heat-
ing or Cooling mode. If HEAT is selected, the thermostat
will only enter Heating mode (if the room temperature is
below the heating set point). If COOL is selected, the ther-
mostat will only enter Cooling mode (if the room tempera-
ture is above the cooling set point). If AUTO is selected, the
thermostat will enter Heating or Cooling mode based on the
room temperature and the heating and cooling set points. If
PROGRAM ON is selected, the stored schedule is enabled
and the thermostat will follow the time period schedules stored
in its memory.
NOTE: The transmitter must be configured to Unit ID Num-
ber 1 to have a programmed schedule.
Auto-Changeover — When the thermostat mode is set
to AUTO or PROGRAM ON, the thermostat will provide
automatic changeover from Heating to Cooling mode and
Cooling to Heating mode when required. The thermostat will
automatically switch to maintain the desired temperature set-
ting. The thermostat does not need to be manually changed
from heating to cooling or cooling to heating operation.
Two-Stage Operation — The second stage of heat or
cool is turned on when the first stage has been on for a mini-
mum of 2 minutes and the temperature differential from the
set point is equal to or greater than the set point plus the
deadband plus 2 degrees.
Fan Operation — If Fan On is selected, the fan will run
continuously during occupied schedule (except when Mode
is switched to OFF). The fan will be off during unoccupied
schedule except during heating or cooling operation.
If Fan On is not selected, the fan will only operate during
heating or cooling operation.
Electric Heat — When the Electric Heat DIP switch on
the receiver is set to ON, the thermostat will turn on the fan
immediately any time there is a heat demand. This feature
should only be used on electric heating applications. Do not
use with gas heat.
Keypad Lock — To prevent unauthorized use of the ther-
mostat, the front panel buttons can be disabled. To disable or
lock the keypad, press and hold the Mode button. While hold-
ing down the Mode button, press the UP and DOWN
ARROW buttons simultaneously. The ‘‘Locked’’ icon will
appear on the display.
The thermostat is unlocked by performing the same pro-
cedure. Press and hold the Mode button. While holding down
the Mode button, press the UPand DOWN ARROW buttons
simultaneously. The ‘‘Locked’’ icon will be removed from
the display.
Unit ID Number — If more than one transmitter (up to
4) is used with a single receiver, the transmitters must be
given different Unit ID Numbers. Only the transmitter with
Unit ID Number 1 may have a programmed schedule or be
