Above the turning knob a LED is placed. This will light when the room
temperature is lower than the desired temperature selected on the
turning knob. The heat is on and is trying to raise the room
temperature to the desired level.
If this LED is off this means that the desired room temperature has
been reached. The heating elements in the HEAT are now off but the
fan continues on the selected level.
When the room temperature falls below the desired level the heating
elements are turned on again and the LED will light up.
In this way HEAT regulates the room temperature constantly to
achieve the most comfortable room temperature I the wagon.
