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.
