T822A,D,F and TS822A Heating and
T822G Heating or Cooling Thermostats
IMPORTANT
— T822A,D,F and TS822A can only be installed in
heating applications. Perform only steps 1-5.
— T822G can be installed in either heating or cooling
applications. If installed for heating, perform steps 1-
5. If installed for cooling, perform step 6.
1. Set T822F Fan switch at Auto. Fan operation is con-
trolled by the thermostat.
2. Move temperature setting lever about 10°F (6°C) above
room temperature.
• Gas or oil heating systems: Heating starts
immediately. Fan starts after short delay.
• Electric heating systems: Heating and fan start
immediately.
3. Move temperature setting lever about 10°F (6°C) below
room temperature.
• Gas or oil heating systems: Heating stops
immediately. Fan stops after a short delay.
• Electric heating systems: Heating and fan stop
immediately.
4. Set T822F Fan switch to On. Fan runs continuously.
5. Set temperature lever and T822F Fan switch to desired
settings.
CAUTION
Equipment Damage Hazard.
Can short-cycle air conditioner compressor.
Install five-minute time delay to prevent operating
compressor for five minutes after thermostat turns off
compressor or for five minutes after system receives
power.
Avoid operating T822G Thermostat in cooling
applications when outdoor temperature is below 50°F
(6°C).
See air conditioner manufacturer recommendations.
6. For T822G cooling applications only:
• To prevent compressor short cycling, install a five-
minute time delay. (The time delay will not activate
the compressor for five minutes after the thermostat
turns off the compressor or for five minutes after the
system receives power.)
• Move the temperature setting lever about 10°F (6°C)
below room temperature. Cooling and fan should
start immediately. Move temperature setting lever
about 10°F (6°C) above room temperature. Cooling
and fan should stop immediately.
