Setting Fuel Switch (T8775C only)
The fuel switch is preset at the factory in the F
position. See Fig. 7. This is the correct setting for gas
or oil systems. If the T8775C is being installed on an
electric heat system, or a heat pump, set the switch to
the E position. The E setting allows the fan to turn on
immediately with the heating equipment in a system
where the G terminal is connected.
