Setting Fan Operation (Fuel) Switch
The fan operation (fuel) switch is preset at the factory in
the F position. See Fig. 8. This is the correct setting for
most systems. If this system is an electric heat system or
single-stage heat pump, set the switch to the E position,
which altows the fan to turn on immediately with the
heating or cooling equip-merit in a system where the G
terminal is connected.

Installing Batteries
The thermostat requires three AA alkaline batteries to
operate:
1. Remove the battery door, located on the right side
of the thermostat, by pulling outward from the bot-
tom. See Fig. 10.
2. Insert the three AA alkaline batteries (included) as
shown in Fig. 10.

The thermostat shows a "bAtLo" message on
the digital disptay to alert the homeowner one to
two months before the batteries run out com-
pletely.
IMPORTANT
Homeowner should replace the batteries once a
year to prevent leakage and/or the heating/cool-
ing system from shutting down due to lack of
battery power in the thermostat.
