Every thermostat is calibrated before it leaves the factory.
Under normal circumstances there will never be a need to
recalibrate the thermostat again.
To accommodate special needs, the thermostat may be recalibrated
following these steps:
1. While holding the mode button in, press the fan button for
5 seconds. After all the icons in the display appear, release
the buttons.
2. Press the Up and Down arrow buttons simultaneously, twice.
3. Press the up or down buttons until the flashing number
equals the current room temperature.
4. Press the mode button to return to normal operation.

STEP #4
TEST OPERATION
Page 9
Press the MODE button repeatedly until
the HEAT icon appears on the display.
Press the Up or Down buttons until the set
temperature is 10 degrees above room
temperature. The furnace should turn on.
Press the MODE button repeatedly until
the COOL icon appears on the display.
Press the Up or Down buttons until the set
temperature is 10 degrees below room
temperature. The air conditioner should
turn on. NOTE: Most equipment has a
time delay of 5 minutes between cool
cycles. This feature is defeatable on the
thermostat. Consult the Owner's Manual
under Setup, cycles per hour.
Turn the power on to the Heating/Air
Conditioning system.
Press the MODE button to OFF. Press
the FAN button to Fan On. The fan

SYMPTOM: When using 4 wires (R, G, W, Y),
the air conditioning equipment tries
repeatedly to turn on, but cannot. At
times the display dims or disappears.
CAUSE: There is not enough power available
to "power share".
REMEDY: Connect a 270 ohm, 10 watt power
resistor at the furnace as shown below.
TROUBLESHOOTING
Page 10
SYMPTOM: The air conditioning does not
attempt to turn on.
CAUSE: The compressor timer lockout may
prevent the air conditioner from
turning on, for a period of time.
REMEDY: Consult the Owner's Manual in
the Setup section to defeat the
cycles per hour and compressor
timeguard.
SYMPTOM: The display is blank.
CAUSE: Lack of proper power.
REMEDY: Make sure power is turned on to
the furnace and 24vac between R& W.
If Cis used, 24vac between R& C.
