STEP 8. CUSTOMIZE THE THERMOSTAT
Set Fuel Switch (CT8775C Only)
❑ To adjust the fuel switch, locate the switch labeled E/F on the wallplate
(see Fig. 3). The fuel switch is factory set in the F position. This is the
correct setting for gas or oil systems. If you have an electric heat
system, or a heat pump, set the switch to E. The E setting allows the
fan to turn on immediately with the heating system where the G
terminal is connected.
DIP Switch
❑ To adjust the heat cycle rate or the Fahrenheit/Celsius indication,
locate DIP switch 1, 2 and 3 on the back of the thermostat. See Fig. 4.
Set Heat Cycle Rate
❑ Use DIP switches 1 and 2 to set the heat cycle rate. See Table 3.
NOTE: The CT8775A,C Thermostats will provide optimal temperature
control if DIP switches 1 and 2 are set according to your partic-
ular heating system.
