Cooling System

!CAUTION

To prevent compressor and/or property damage, if the outdoor temperature is below 50°F, DO NOT operate the cooling system.

1. Move SYSTEM switch to COOL position.

2.Press to adjust thermostat setting below room tempera- ture. The blower should come on immediately on high speed, followed by cold air circulation

3.Press to adjust temperature setting above room tem- perature. The cooling system should stop operating.

Before you begin programming your thermostat, you should be familiar with its features and with the display and the location and operation of the thermostat buttons. Your thermostat consists of two parts: the thermostat cover and the base. To remove the cover, pull it straight out from the base. To replace the cover, line up the cover with the base and press until the cover snaps onto the base.

THE THERMOSTAT BASE

Other than and , the following buttons and switches are located on the bottom of the thermostat cover (see fig. 8).
