Your new White-Rodgers thermostat uses solid state microcomputer technology to provide precise time/temperature control. This thermostat offers the flexibility to design heating and cooling programs that fit your needs. Adaptable to most 24 volt residential forced air, multistage or heat pump systems with electric or fossil fuel auxiliary (1F92-371). You will find information about thermostat buttons and display in the component section beginning on page 2. Installation instructions begin on page 4. Instructions for optional thermostat configuration begin on page 23. Programming information begins on page 26. Descriptions of the thermostat’s features begin on page 30. We have also added thumb tabs to help you find sections of the manual. 1 Introduction Orientation Installation Programming Features Index Configuration ORIENTATION ORIENTATION THE THERMOSTAT BUTTONS THE THERMOSTAT BUTTONSTHE THERMOSTAT BUTTONSTHE THERMOSTAT BUTTONSTHE THERMOSTAT BUTTONSTHE THERMOSTAT BUTTONS See inside front cover for illustration showing button locations. 1 (Blue arrow) Lowers temperature setting (45°F or 7°C minimum) 2 (Red arrow) Raises temperature setting (99°F or 37°C maximum) 3 The multi-color indicator glows: green for 1st stage, yellow for 2nd stage, red for emergency heat and flashing red for malfunction condition in system. 4 This button (on top of the cover) lights the display. 5 Used to initiate or review thermostat programming or advance to next program period in programming mode. 6 Used with TIME FWD /TIME to set the clock.
