Temperature Control
There are many types and styles of thermostats. Yours may look different from the one shown in Figure 2. How- ever, almost all thermostats perform the same basic functions described in the following section.

Thermostat Operation
There are two switches located on the thermostat (see Figure 2). One switch controls the heating and cooling functions. The other switch is for “FAN” operation, either continuous or automatic. On the thermostat is the temperature range for the heating temperature and the cooling temperature desired.
To put the system into operation, push the switch to either “HEAT” or “COOL” position. After choosing the type of operation, move the thermostat dial or lever to select the temperature you would like the system to maintain.
Fan Operation
You may wish to increase your comfort by setting your system for continuous air circulation of the indoor air. The fan switch on the thermostat permits you to do this.
With the switch in the “ON” position the fan will operate continuously. “AUTO” position gives fan operation only when the unit is in either heating or cooling.
Unit Operation
If your unit is operating but fails to provide complete comfort, check the following before calling for service:
1.Be sure the thermostat setting is correct.
2.Check to see if the filter is clean.
3.Be sure air can circulate freely throughout your home. Do not block supply registers or return grilles with furniture or rugs.
4.Keep surface of the outdoor coil free from dirt, lint, paper, or leaves.
If your unit fails to operate, check the following:
1.Be sure the main switch that supplies power to the unit is in the “ON” position.
2.Replace any
3.Be sure the thermostat is properly set.
If the unit still does not start, call a qualified service technician.
