STEP 4
SET THE SYSTEM AND FAN
SWITCHES ON THE SUBBASE.
Depending on thermostat model, some
of the switch positions shown may not
be available to you. Note the positions
provided on your subbase, then set the
switch(es) as desired.
First set the fan switch.
FAN ON: The fan runs continu-
ously. Use for improved air
circulation during special occa-
sions or for more efficient
electronic air cleaning.
FAN AUTO: Normal setting for
most homes. The fan goes on
and off with the air conditioner in
summer. In winter, the fan on
most systems starts a few
minutes after the furnace comes
on. It stops a few minutes after
the furnace goes off. The fan
starts and stops with the furnace
in some electric heat systems and
with the compressor in heat pump
systems.
