WARNING
T HERMOSTAT F 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 thermostat only
starts and stops the furnace to maintain the desired 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 circulating 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 cooling functions. The level of this control
depends on the type of thermostat applied.
