NEVER TOUCH YOUR HEATER OR ITS CASING WITH WET HANDS!

Power indicator

See figure 3 on separate illustration sheet

If the heater uses power (for example, when it heats up), the power indicator is on

Temperature calibration

See figure 4 on separate illustration sheet

It may occur deviation between the temperature registered by the heater and the actual temperature in the room. This can be caused by several reasons, however, the most common is that the heater is placed in a fair distance from where you usually reside. When you set the temperature to for example 22 degrees, it is only natural that you expect the same temperature where your sofa is placed for instance. However, the temperature sensor is placed on the product itself, and therefore a deviation in temperature may occur. To adjust this, all Mill heaters are equipped with a calibration function, which enables you to adjust the temperature registered by the heater. N.B! The room must have achieved a stable temperature before any calibration.
Press to enter the menu and use + and - button to navigate the menu until you see "CAL" in the display. Press to enter calibration mode. The registered room temperature will blink on the display. Use + or - button to set the actual temperature observed in the room. Confirm with or wait 10 seconds for automatic confirmation. (Can be done even if you are connected to WiFi)
