• Your system may also be equipped with a zoning system which
allows individual control over the temperatures of separate areas
of your home.
• Your air conditioner will remove humidity from your home
during the cooling season. After a few minutes of operation, you
should be able to see water trickle from the condensate drain of
the cooling coil. Check this occasionally to be sure the drain
system is not clogged. Of course, don't expect to see much
drainage if you live in a very dry environment.
• Your unit is not designed to be operated when outdoor tem-
peratures are lower than 55°F without modification. If opera-
tion below this temperature is required, consult your installer.

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 temperature at the level you select. Most
thermostats have three controls: a temperature control selector,
a FAN control, and a SYSTEM or MODE control. Fig. 2 and 3
show typical Carrier thermostats.
The temperature control selector is a dial, lever, or set of buttons that
allows you to select the temperature you wish to maintain for your
personal comfort. Some thermostats possess two temperature
