Cooling System

This thermostat has a built-in short-term (5-minute) time delay. This feature is activated after the compressor shuts down and the setpoint is changed within the 5-minute period. During this 5-minute period, COOL will flash on the display indicating that the thermostat has locked out the compressor to allow head pressure to stabilize. This thermostat does not sense AC power loss and therefore does not activate the short term compressor protection feature when power is restored.

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.

!CAUTION

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

OPERATION

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, gently pull it straight out from the base. To replace the 1 cover, line up the cover with the base and press gently until the cover snaps onto the base.
