•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 removes 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.

•Do not operate your unit when outdoor temperatures are below 55°F.

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.

The temperature control selector can be a dial, lever, or set of buttons that allows you to establish the degree of temperature you wish to maintain for your personal comfort. Some thermo- stats possess two temperature control selectors: one for setting the temperature desired for cooling operation, and one for set- ting the temperature 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 thermostat operates the cooling or heating equip- ment. When set to ON, the blower runs continuously—regard- less of whether the cooling or heating equipment is operating.

Typically, the SYSTEM or MODE control on your thermostat offers the following selections: COOL, OFF, and HEAT. Your thermostat may also have a fourth selection, AUTO. Neither the cooling nor heating equipment will operate when the SYSTEM
