(when not using
j-box)
Proper installation of the thermostat will be
accomplished by following these step by step
instructions. If you are unsure about any of
these steps, call a qualified technician for
assistance.
Assemble tools.
Flat Blade
Screwdriver
Wire cutter
& Stripper
Make sure your Heater/Air Conditioner is
working properly before beginning installation
of the thermostat.
Carefully unpack the thermostat. Save the
screws, wall anchors, and instructions.
Turn off the power to the Heating/Air
Conditioning system at the main fuse panel.
Most residential systems have a separate
breaker for disconnecting power to the furnace.

Remove the cover of the old thermostat.
If it does not come off easily check for
screws.
Loosen the screws holding the thermostat
base or subbase to the wall, and lift away.
Disconnect the wires from the old
thermostat. Tape the ends of the wires
as you disconnect them, and mark them
with the letter of the terminal for easy
reconnection to the new thermostat.
Keep the old thermostat for reference
purposes, until your new thermostat is
functioning properly.

STEP #5
TEST OPERATION
Press the MODE button repeatedly until
the HEAT icon appears on the display.
Press the UP or DOWN button until the set
temperature is 10 degrees above room
temperature. The HVAC unit should
energize in the heating mode.
Press the MODE button repeatedly until
the COOL icon appears on the display.
Press the UP or DOWN button until the set
temperature is 10 degrees below room
temperature. The HVAC unit should
Turn the power on to the Heating/Air
Conditioning system.
energize in the cooling mode.
Press the UP button until the setpoint is
equal to the room temperature. Press the
FAN button to Fan On. The fan should turn
on and run continuously.
NOTE: Most equipment has a time delay
of 5 minutes between cooling cycles. This
feature is defeatable on the thermostat
(see page 13, step 8 of the Thermostat
Manual).

TROUBLESHOOTING
SYMPTOM: When using 4 wires (R, G, W, Y),
the air conditioning or heating equipment
tries repeatedly to turn on, but cannot.
CAUSE: There is not enough power available
to "power share".
REMEDY: Connect a 250 ohm, 10 watt power
resistor at the furnace as shown below.
R G W Y C
TR300-10w
R G W Y C
TR300-10w
For Problem A/C
Note: 2 resistors may be used at the same time.
Not applicable with Heat Pump systems.
For Problem Heat
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: See page 13 of the Thermostat
Manual and configure step 8 to defeat
the 5-minute compressor lockout.
SYMPTOM: The display is blank.
CAUSE: Lack of proper power.
REMEDY: Make sure power is turned on to
the furnace and 24vac exists between
R& W. If Cis used, 24vac between R& C.

SYMPTOM: When controlling a residential heat
pump, and asking for cooling, the heat
comes on.
CAUSE: The Heat Pump dip switch is set to OFF.
REMEDY: See page 5 of this manual and set the
Heat Pump (HP) switch to ON.
TROUBLESHOOTING
SYMPTOM: When calling for cooling, both
the heat and cool come on.
CAUSE: The Heat Pump dip switch is set to ON
and the HVAC system is a "conventional"
(non-heat pump) system.
REMEDY: See page 5 of this manual and set the
Heat Pump (HP) switch to OFF to enable gas
electric operation.
