Possible Causes

Thermostat installed in atypical room (hallway, near door), No zoning for different areas, Radiators without thermostatic valves, Incorrect use of remote sensors

How to Fix / Troubleshooting

Safety: No electrical work required unless relocating the thermostat.

  • Step 1 – Evaluate location: The thermostat should be in a frequently used room, about 1.5 m above the floor, away from drafts and heat sources.
  • Step 2 – Use remote sensor: If supported, install an Immergas remote room sensor in the main living area and configure the thermostat to use it.
  • Step 3 – Add zoning: Consider installing Immergas zone control modules and additional thermostats for separate areas.
  • Step 4 – Balance radiators: Adjust radiator valves or install thermostatic radiator valves to balance heat distribution.
