19 69-1385
Step 5. Adjust Fan Operation
Switch, As Required
❑
The thermostat fan operation switch, labeled
FUEL SWITCH (see illustration) 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 to allow the
fan to turn on immediately with the heating in
a system when the G terminal is connected.
Step 6. Adjust System On-Time,
°F/°C, As Required
❑
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 screws A
and B on the back of the thermostat. Use the
heating system table shown in the illustration
as a guide. The system on-time should be
optimized according to the type of system to
maximize comfort. Setting the screw “out one
turn” means turning the screw approximately
360° counterclockwise, or about one com-
plete turn.
