CHECK THERMOSTAT OPERATION
If at any time during testing your system does not operate
properly, contact a qualified serviceperson.
Fan Operation
If your system does not have a G terminal connection, skip to
Heating System.
1. Turn on power to the system.
2. Move FAN switch to ON position. The blower should begin
to operate.

3. Move FAN switch to AUTO position. The blower should stop
immediately.
Heating System
1. Move SYSTEM switch to HEAT position. If the heating
system has a standing pilot, be sure to light it.
2. Press to adjust thermostat setting above room tempera-
ture. The heating system should begin to operate.
3. Press to adjust temperature setting below room tempera-
ture. The heating system should stop operating.
