OPERATING YOUR UNIT

The operation of your system is controlled by the indoor
temperature control (Thermostat). Your gas heating /

electric cooling unit requires a thermostat with 2 stages of
cooling and 1 stage of heating. You simply adjust the

thermostat and it maintains the indoor temperature at the

level you select. Most thermostats of heating and cooling

systems have 3 controls: a temperature control selector, a

FAN control, and a System or MODE control. Refer to your

thermostat owner's manual for more information.
