British Gas PT Plus 22089 User Instructions

If the British Gas PT Plus 22089 controller is not operating the boiler after replacing the batteries, consider the following possible causes and solutions:

1. Battery Installation Issues
- Ensure the batteries are inserted correctly, matching the correct polarity (+ and -).
- Use fresh, high-quality alkaline batteries, as low-power or rechargeable batteries may not work properly.

2. Controller Reset Required
- Some models may require a reset after battery replacement. Look for a reset button or remove and reinsert the batteries after a few minutes.

3. Signal Loss Between Controller and Boiler
- If the controller is wireless, it may have lost its connection to the receiver near the boiler. Try re-pairing the controller with the receiver according to the manufacturer’s instructions.
- Check for interference from other wireless devices.

4. Receiver or Boiler Not Responding
- Ensure the receiver is powered and showing status lights. If not, check the power supply and circuit breakers.
- Manually override the receiver (if possible) to check if the boiler responds.

5. Faulty Controller or Receiver
- If the controller display is blank or unresponsive, the unit may be faulty and need replacement.
- If the receiver does not activate the boiler when manually triggered, it could be faulty.

6. Boiler Issues
- Ensure the boiler has power and is set to the correct mode.
- Check for boiler error codes or low water pressure that might prevent operation.

If these steps do not resolve the issue, professional servicing may be needed.

Yes, on the British Gas PT Plus 22089, manual mode overrides all other modes. When manual mode is selected, the thermostat maintains a constant temperature set by the user, ignoring any pre-programmed schedules or automatic settings. This allows for direct control of the heating system without interruption from programmed time periods or temperature changes.

The British Gas PT Plus 22089 thermostat displays two key temperatures: the set temperature (desired room temperature) and the actual room temperature (current temperature). If it shows 24 degrees while set to 20 degrees, the likely reasons are:

1. Current Room Temperature: The 24 degrees displayed is the actual room temperature, which is higher than the set temperature of 20 degrees. This could happen if external factors, such as warm weather, heating from appliances, or sunlight, are raising the room's temperature.

2. Thermostat Placement: If the thermostat is placed near a heat source (e.g., radiators, electronics, or direct sunlight), it may detect a higher temperature than the rest of the room.

3. System Overheating: If the heating system isn't turning off properly, it might continue to heat the room beyond the set temperature. This indicates a potential issue with the thermostat's communication with the heating system.

4. Calibration Issue: The thermostat may be misreading the temperature due to a calibration error, causing it to display incorrect readings.

### Steps to Address the Issue:
- Check Placement: Ensure the thermostat is in a central location, away from heat sources or direct sunlight.
- Inspect Heating System: Verify that the heating system stops when the set temperature is reached.
- Reset or Recalibrate: Reset the thermostat to factory settings or check the user manual for calibration instructions.
- Contact Support: If the issue persists, consult a qualified technician for further diagnosis.
