Adjust Fan Operation Switch
³ The thermostat fan operation switch,
labeled FUEL SWITCH (see illustration on
page 14), is factory-set in the F position.
This is the correct setting for most
systems. If your system is an electric heat
system, set the switch to E. The E setting
allows the fan to turn on immediately with
the heating or cooling in a system where
the G terminal is connected.

³ The thermostat on-time is factory-set for
a warm air, gas or oil heating system. If
you are installing it on another type of
system, adjust the on-time accordingly by
setting DIP switches 1 and 2 on the back
of the thermostat. Use the heating
system table on the thermostat back as a
guide.
Optimize the system on-time according to the
type of system to minimize room temperature
swings.
In the unlikely event that you want a longer
furnace on-time, readjust DIP switches 1 and 2
as follows:
•Warm Air Furnace—set at the Hot Water
setting (1—OFF, 2—ON).
• Electric Furnace—leave at the Warm Air
Furnace setting (1—ON, 2—OFF).
