Possible Causes
How to Fix / Troubleshooting
Safety first: Isolate power before moving or opening the receiver.
Steps to improve RF reliability:
- 1. Reposition receiver: If possible, move the receiver away from metal objects, large appliances, or inside cupboards. Mount it in a more open location.
- 2. Reduce interference: Keep the thermostat and receiver away from Wi‑Fi routers, cordless phone bases, and baby monitors.
- 3. Shorten distance: If the thermostat is at the far end of the property, consider relocating it closer to the receiver or using a Baxi-approved repeater if available.
- 4. Re-pair devices: Perform a fresh pairing between thermostat and receiver following Baxi instructions.
When to call a professional: Persistent dropouts may indicate failing RF hardware; a heating engineer can test and replace the faulty module.
