How to Fix / Troubleshooting

Safety first: Turn off mains power before checking wiring.

Steps to check:

  • Tighten wiring: Ensure all live, neutral, and any low-voltage connections are secure at the thermostat and receiver.
  • Check supply quality: If other devices on the same circuit flicker or reset, have an electrician check for supply issues.
  • Replace batteries: If the thermostat uses batteries for backup, replace them.
  • Factory reset: Perform a factory reset to clear any corrupted settings that might cause resets.

Resolution: If random resets continue with good wiring and supply, replace the thermostat head.
