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.
STEP #2

Calibration
Every TR7DRH is calibrated before it leaves the factory.
Under normal circumstances there will never be a need to recalibrate
the TR7DRH 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 & down arrow buttons simultaneously. The display will
change.
3. Press the up & down buttons simultaneously, again. The current room
temperature will be displayed.
4. Use an accurate thermometer to measure room temperature. Press the
up or down arrow buttons until the displayed temperature equals the room
temperature.
5. Press the up & down buttons simultaneously, again. The current humidity
will be displayed.
6. Use an accurate hygrometer to measure room humidity. Press the up or
down arrow buttons until the displayed humidity equals the room humidity.
7. Press the mode button to return to normal operation.
