SECTION II: THERMOSTATS
YOUR KEY TO COMFORT
Though thermostats may vary widely in appearance they are all
designed to perform the same basic function, to control the operation of
your air conditioning system. Regardless of size or shape, each thermo-
stat will feature a temperature indicator; a dial, arm, or push button for
selection of the desired temperature; a fan switch to choose the indoor
fan operation; and a comfort switch for you to select the system mode
of operation.
COOLING ONLY
If your air conditioning system is designed to provide cooling only (AC),
with no capability for heating operation (electric heat), a single-stage
cooling only thermostat, with a manual, one-position "Cool" and "Off"
comfort switch is all that is required for system operation.
NOTE: If you have an independent heating system (with a separate
thermostat), always be sure the heating control is turned "Off"
before turning on the cooling system.
COOLING AND HEATING
If your system has been designed to allow both cooling and heating
operation, you may have either a manual change-over type, or a pro-
grammable electronic type thermostat.
MANUAL CHANGE-OVER
Manual change-over simply means that the comfort switch must be
manually positioned every time you wish to switch from the cooling to
heating or heating to cooling modes of operation.
