The White-Rodgers 1F80-224 is a programmable digital thermostat designed for low voltage heating and cooling systems. Before installation, ensure the power is disconnected at the main fuse box. The unit requires 2 AA alkaline batteries (included). Programming allows for four separate time/temperature settings per day. If the system does not operate, check the fuse, furnace power switch, and wiring connections.
Description and Features
This thermostat uses solid-state microcomputer technology for precise time and temperature control. Key features include:
- Simultaneous heat and cool program storage.
- Four separate time/temperature settings.
- Temporary and manual temperature hold functions.
- Fahrenheit/Celsius convertibility.
- Compressor lockout protection.
- LCD display showing setpoint, time, and room temperature.
Installation
Warning: This thermostat is for low voltage systems only. Do not use with line voltage systems.
Removing the Old Thermostat
- Shut off electricity at the main fuse box.
- Remove the front cover of the old thermostat.
- Identify each wire using the provided labels before disconnecting.
- Disconnect wires one at a time, ensuring they do not fall back into the wall.
Attaching the Base
- Remove the packing material and pull the cover straight off the base.
- Connect wires to the terminal screws on the base according to the appropriate wiring schematic (see figures 2-7 in the manual).
- Place the base over the wall hole, mark mounting locations, drill holes, and fasten the base to the wall.
- Push excess wire into the wall and plug the hole with fire-resistant material to prevent drafts.
Battery Installation
The thermostat includes 2 AA alkaline batteries. You must remove the battery tag to engage the batteries. If "BATT" is displayed, replace the batteries with fresh AA alkaline batteries. Install them along the top of the base with the positive (+) end to the left.
Operation and Programming

- Press the TIME button once.
- Use the arrow buttons to set the hour (ensure correct AM/PM designation).
- Press TIME again and use the arrow buttons to set the minutes.
Programming Heating and Cooling
- Move the SYSTEM switch to HEAT or COOL.
- Press PRGM to view the 1st period start time and temperature.
- Use the arrow buttons to adjust the temperature.
- Press TIME to switch to time adjustment, use arrows to set the time, then press TIME again to return to temperature adjustment.
- Press PRGM to move to the next period.
- Repeat for all four periods, then press RUN.
Configuration Menu
To customize settings like cycle rate (FA/SL), backlight, or compressor lockout, press RUN, then press PRGM and RUN simultaneously. Use HOLD to advance through menu items and the arrow buttons to change settings.
Troubleshooting
