The 24 Volt neutral connection to terminal C on the thermostat is not required if the batteries are replaced once a year with fresh "AA" Energizer® alkaline batteries.

Heating System

1.Move SYSTEM switch to HEAT position. If the heating system has a standing pilot, be sure to light it.

2.Press to adjust thermostat setting above room tempera- ture. The heating system should begin to operate.

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

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 tem- perature. 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.
