HERMOSTAT UNCTIONS
There are many types and styles of thermostats but opera-
tion is usually similar. BE SURE TO BECOME FAMILIAR
WITH YOUR THERMOSTAT. The simplest type of thermo-
stat only starts and stops the furnace to maintain the de-
sired room temperature. The most widely used types will
control both heating and cooling functions and will have a
Fan Switch with Auto and ON settings. On Auto, the circulat-
ing air blower will cycle on/off with the furnace but if switched
to ON it will run continuously regardless of whether or not
heating or cooling is being provided.
In addition, there are thermostats which automatically switch
from heating to cooling mode and those with night set back
capability. The night set back, or multiple set back, type
allows for a different temperature at night or during the day
when no one is at home. Programmable thermostats will
allow for more control and tailoring of the heating and cool-
