Thermostat shows correct temperature but floor feels cold

Safety first: Configuration changes can be made without opening the unit.

Steps to troubleshoot:

• 1. Increase setpoint:
  • Raise the room or floor setpoint gradually and monitor comfort.
• 2. Check max floor temperature:
  • In the installer menu, verify that max floor temp is not set too low (e.g. 20–22°C).
  • Increase within safe limits for your floor covering.
• 3. Verify heating cable power:
  • Check the installed floor heating wattage per m² against room heat loss; low wattage may not be sufficient.
• 4. Sensor depth:
  • If the sensor is buried too deep, it may read warmer than the surface; consider using room sensor control with floor limit.
