The White Rodgers 1F87-361 is a 7-day programmable digital thermostat designed for low-voltage heating and cooling systems. This guide covers essential installation, programming, and troubleshooting steps. Always disconnect power at the main fuse box before beginning installation.
Installation
Before installing, ensure your system is compatible (low voltage). Do not use with line voltage systems.
- Remove Old Thermostat: Shut off electricity. Remove the front cover, label wires, and disconnect them. Do not let wires fall back into the wall.
- Mounting: Remove packing material. Pull the cover off the base. Use the base as a template to mark mounting holes. Drill holes and fasten the base to the wall.
- Wiring: Connect wires to terminal screws according to the specific wiring diagram for your system (Heat only, Cool only, Heat/Cool, or Heat Pump).
- Batteries: Install 2 AA alkaline batteries. Remove the battery tag to engage power.
Operation and Programming
The thermostat features a configuration menu and programmable schedules.
Setting Time and Day
- Press the TIME button.
- Use the arrow buttons to set the hour (ensure correct AM/PM).
- Press TIME again to set minutes.
- Press TIME again to set the day of the week.
- Press RUN to finish.
Entering Programs
- Move the SYSTEM switch to HEAT or COOL.
- Press PRGM to enter programming mode.
- Use the arrow buttons to adjust the temperature for the 1st period.
- Press TIME to switch to time adjustment, then use arrows to set the start time.
- Press PRGM to move to the next period.
- Repeat for all periods and days.
Configuration Menu
To enter the configuration menu, ensure the thermostat is in RUN mode, then press PRGM and RUN simultaneously. Use the HOLD button to advance through menu items (e.g., Temporary Hold Time, Cycle Rate, Backlight, EMR, Filter replacement, Compressor Lockout, Temperature adjustment, F/C readout).
Troubleshooting
If the thermostat does not function correctly, verify wiring connections and ensure the system switch is set to the correct mode (HEAT or COOL). If the display is blank or the unit is unresponsive, replace the batteries or perform a reset by pressing the arrow buttons and TIME simultaneously.
Practical help
Common problems
No Heat/No Cool/No Fan
Check for a blown fuse or tripped circuit breaker. Ensure the furnace power switch is ON and the blower door is properly installed.
Thermostat does not follow program
Check that AM/PM settings are correct for both the clock and the program periods. Perform a reset if necessary.
Blank display or unresponsive keypad
Replace batteries. If the issue persists, perform a reset by pressing the arrow buttons and TIME simultaneously.
Heat/Cool runs constantly
Check if the FAN switch is set to ON. Verify wiring for shorts.
Before use
