Adjust Fan Operation Switch, As Required
The thermostat fan operation switch, labeled
FUEL SWITCH (see figure on page 17) 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 will
allow the fan to turn on immediately with the
heating or cooling in a system where the “G”
terminal is connected.
The thermostat on-length is factory-set for a
warm air, gas or oil heating system. If you are
installing it on another type of system, the on-length
must be adjusted accordingly by setting screws A
and B on the back of the thermostat, using the
heating system table in the figure
(page 17) as a guide. The on-length should be
optimized according to the type of system to
minimize room temperature swings. Setting the
screw “out one turn” means turning the screw
approximately 360°, or about one complete turn.
In the rare event that you want a longer on-length, you may readjust the screws as follows:
