[. . . ] 1F80-24 WHITE-RODGERS Programmable Electronic Digital Thermostat INSTALLATION AND OPERATION INSTRUCTIONS Operator: Save these instructions for future use! FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE PERSONAL INJURY AND/OR PROPERTY DAMAGE. DESCRIPTION Your new White-Rodgers Digital Thermostat uses the technology of a solid-state microcomputer to provide precise time/ temperature control. This thermostat offers you the flexibility to design heating and cooling programs that fit your needs. Features: · Battery powered (3 "AA" Energizer® alkaline batteries included) · Same program for all days of the week · Simultaneous heat and cool program storage · Four separate time/temperature settings per program · Preprogrammed temperature control · LCD continuously displays set point, and alternately displays time and room temperature · Temperature override until next program period · Manual program override (HOLD temperature) · User may select either 12- or 24-hour clock display · °F/°C convertibility · Temperature range 45° to 90°F · Standard five terminals for single or dual transformer systems · B & O terminals for single stage heat pumps or damper operation PRECAUTIONS This thermostat is intended for use with a low voltage system; do not use this thermostat with a line voltage system. If in doubt about whether your wiring is millivolt, line, or low voltage, have it inspected by a qualified heating and air conditioning contractor or electrician.

The blower should stop immediately. Heating System 1. If the heating system has a standing pilot, be sure to light it. Press to adjust thermostat setting above room tempera- Fan Operation If your system does not have a G terminal connection, skip to Heating System. The heating system should begin to operate. Press to adjust temperature setting below room tempera- ture. The heating system should stop operating. 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. 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. [. . . ] You may also want to look at the sample program table to get an idea of how the thermostat can be programmed.
