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.
