OPERATING YOUR AIR CONDITIONER
The operation of your air conditioning system is controlled by
the indoor thermostat. You simply adjust the thermostat and it
maintains the indoor telnperamre at the level you select. Most
therlnostats have three controls: a telnperamre control selector,
a FAN control, and a SYSTEM or MODE comrol.
The telnperature control selector can be a dial, lever, or set of
buttons that allows you to establish the degree of telnperature
you wish to lnaintain for your personal COlnfort. Some therlno-
stats possess two telnperature control selectors: one for setting
the telnperature desired for cooling operation, and one for set-
ting the telnperature desired for heating operation.
The FAN control offers two options for controlling the indoor
blower: AUTO and ON. When set to AUTO, the blower runs
only while the therlnostat operates the cooling or heating equip-
ment. When set to ON, the blower runs continuously--regard-
less of whether the cooling or heating equiplnent is operating.
Typically, the SYSTEM or MODE control on your therlnostat
offers the following selections: COOL, OFF, and HEAT. Your
therlnostat may also have a fourth selection, AUTO. Neither the
cooling nor heating equiplnent will operate when the SYSTEM
