Incorrect room temperature on the controller: causes and diagnosis

If the temperature displayed by the controller differs from the actual temperature, the entire heating strategy may be affected.

Potential causes

Incorrect sensor placement, offset, heat from walls or electronics, or wiring issues.

Comparison

Measurement is performed with an independent thermometer at the same location, and the consistency of the deviation is then checked.

Correction

Calibration offset is only used when a consistent, small deviation has been confirmed.
