The White Rodgers 1F80-0224 is a 24-hour programmable thermostat for single-stage heating and cooling systems. It features digital programming, manual overrides, and compatibility with various 24V HVAC systems. Requires batteries. Below are the key specifications, installation, operation, programming, and troubleshooting instructions.
This thermostat is intended for use with a low voltage NEC Class II system. Do not use on circuits exceeding specified voltage. Higher voltage will damage control and could cause shock or fire hazard. Do not exceed the specification ratings. Do not short out terminals on gas valve or primary control to test. Short or incorrect wiring will damage thermostat and could cause personal injury and/or property damage. All wiring must conform to local and national electrical codes and ordinances. This control is a precision instrument, and should be handled carefully. Thermostat installation and all components of the system shall conform to Class II (current limited) circuits per the NEC code.
CAUTION! To prevent electrical shock and/or equipment damage, disconnect electric power to system at main fuse or circuit breaker box until installation is complete. FAILURE TO READ AND FOLLOW ALL INSTRUCTIONS CAREFULLY BEFORE INSTALLING OR OPERATING THIS CONTROL COULD CAUSE PERSONAL INJURY AND/OR PROPERTY DAMAGE.
APPLICATIONS 1F80-0224 Thermostat For use with the following Class II systems: Single Stage systems, Single-stage heat pump systems with no Aux heat. DO NOT USE WITH: Systems exceeding 30 VAC and 1.5 amps, 3-wire zoned hydronic heating systems.
The 1F80-0224 thermostat includes terminals for R, O/B, Y, G, W, C; buttons for time, program, run/hold; switches for fan and system.

The Thermostat Buttons and Switches:
Shut off electricity at the main fuse box until installation is complete. Ensure that the electrical power is disconnected. Remove the front cover of the old thermostat. With wires still attached, remove wall plate from the wall. If the old thermostat has a wall mounting plate, remove the thermostat and the wall mounting plate as an assembly. Identify each wire attached to the old thermostat using the labels enclosed with the new thermostat. Disconnect the wires from the old thermostat one at a time. DO NOT LET WIRES FALL BACK INTO THE WALL.
Remove the packing material from the thermostat. Gently pull the cover straight off the base. Forcing or prying on the thermostat will cause damage to the unit.

NOTE ACCESSORY RELAY N.O. CONTACT. The accessory relay scheme is required when safety circuits exist in both systems.
If at any time during testing your system does not operate properly, contact a qualified service person. Turn on power to the system. CAUTION! Do not allow the compressor to run unless the compressor oil heaters have been operational for 6 hours and the system has not been operational for at least 5 minutes.
If your system does not have a G terminal connection, skip to Heating System.
CAUTION: To prevent compressor and/or property damage, if the outdoor temperature is below 50°F, DO NOT operate the cooling system.
The configuration menu allows you to set certain thermostat operating characteristics to your system or personal requirements. To enter the menu: Set your thermostat to OFF and press the up and down buttons simultaneously. The display will show the first item in the configuration menu. Press RUN/HOLD to change to the next menu item or press TIME to go backwards to the previous item in the menu. To exit the menu and return to the program operation, press PRGM. If no keys are pressed within fifteen minutes, the thermostat will revert to normal operation.

This section will help you plan your thermostat’s program to meet your needs. For maximum comfort and efficiency, keep the following guidelines in mind when planning your program. When heating (cooling) your building, program the temperatures to be cooler (warmer) when the building is vacant or during periods of low activity. During early morning hours, the need for cooling is usually minimal.
Look at the factory preprogrammed times and temperatures shown in the sample schedule. If this program will suit your needs, simply press the RUN/HOLD button to begin running the factory preset program.
Determine the time periods and temperatures for your program. You must program four periods for each day. However, you may use the same heating and cooling temperatures for consecutive time periods.
