Step-by-Step Installation Guide
1. Remove the Old Thermostat
- Turn the old thermostat counterclockwise to detach it from the wall plate.
- Label the wires connected to the terminals on the back of the old thermostat.
2. Mount the New Thermostat Wall Plate
- Align the new thermostat wall plate over the existing holes in the wall.
- Secure the wall plate with the screws provided.
3. Connect the Wires
- Strip about 1/2 inch of insulation from the ends of the two wires.
- Connect the red wire to the “R” terminal on the new thermostat.
- Connect the white wire to the “W” terminal on the new thermostat.
4. Secure the Wires
- Wrap electrical tape around the exposed wire ends to prevent short circuits.
- Tuck the wires neatly into the wall plate.
5. Mount the Thermostat
- Align the thermostat over the wall plate and gently push it into place.
- Turn the thermostat clockwise to secure it.
6. Restore Power
- Turn on the power at the circuit breaker or fuse box.
- The thermostat should power up and display the current temperature.
7. Test the Thermostat
- Adjust the temperature setting on the thermostat.
- Wait a few minutes for the system to respond.
- The temperature in the room should change accordingly.
Troubleshooting
- Thermostat not powering up: Verify that the power is turned on and that the wires are properly connected.
- System not responding to thermostat: Check that the wires are connected to the correct terminals on both the thermostat and the system.
- Inaccurate temperature readings: Calibrate the thermostat by following the manufacturer’s instructions.
