hookup.
5 ADJUST FAN OPERATION
SWITCH
The thermostat fan operation switch, labeled fuel switch
in Fig. 11, is set at the factory in the F (gas/oil fuel)
position. This is the correct setting for most systems. If
you have an electric heat system, set the switch to the E
(electric) position. The E setting allows the fan to turn on
immediately with the heating equipment in a system
where the G terminal is connected.See Fig. 11.

7 INSTALLING AND REPLACING
BATTERIES
The thermostat requires three AA alkaline batteries to
operate:
Remove the battery door, located on the right side of
the thermostat, by pulling outward from the bottom.
See Fig. 13.
Insert three AA alkaline batteries as shown in Fig. 13.
NOTE: The thermostat shows a “bAtLo” message on
the digital display 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.
