Possible Causes
Loose power connection at backplate, Overloaded 24 V transformer, Internal regulator overheating, Firmware instability
How to Fix / Troubleshooting
Safety first: Turn off power before removing the thermostat.
Steps:
- 1. Check backplate fit: Ensure the thermostat is firmly seated on the backplate and that spring contacts are not bent.
- 2. Tighten power terminals: Verify live and neutral are secure and not shared with high‑load devices that cause voltage dips.
- 3. Reduce load on transformer: If multiple devices share a 24 V transformer, consider adding a dedicated transformer for the thermostat.
- 4. Firmware update and reset: Update firmware via the app and perform a factory reset if reboots continue.
- 5. Replace thermostat: Persistent random reboots with stable power indicate an internal fault.
