Possible Causes

Installed above radiator or other heat source, Poor ventilation behind thermostat, Internal component failure causing excess current draw, Overloaded power supply in Ngenic control module

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.
