The thermostats in our heaters are designed to be precise to within 0.2 degrees (plus or minus). However, slight deviations can occur due to factors such as air currents in the room or if the heater is placed a distance away from where one normally resides.
Most heaters with a digital display can be calibrated to compensate for these variations. Please refer to the user manual specific to your heater for guidance. User manuals are available on our support page.
Wi-Fi-enabled heaters and the Wi-Fi Socket can be calibrated through settings in the Mill app.
However, heaters with a mechanical thermostat, as well as heaters manufactured before 2017, cannot be calibrated.
