How to Fix / Troubleshooting
Safety: If the casing is too hot to touch comfortably, turn off power immediately at the breaker or isolation switch.
- Check installation location: Ensure the thermostat is not directly above a radiator, fireplace, or in direct sunlight.
- Improve ventilation: Do not cover the thermostat or control module with furniture, curtains, or insulation.
- Monitor temperature: After relocating or improving airflow, monitor the device; it should be warm but not uncomfortably hot.
If overheating persists in a suitable location, an internal fault may pose a safety risk. Replace the affected Ngenic thermostat or control module.
