The sauna heater is controlled by operating a 12-hour timer with three operating zones. The timer is set by twisting the knob clockwise until the desired operating zone is reached. When operating, the timer gradually travels counter-clockwise towards the zero position.
Before turning the sauna heater on, make sure the sauna room is suitable for taking a sauna bath.
The timer operates better if it is first turned further than the desired time and then turned back to the desired time. If the switch has not travelled back to 0 position after finishing bathing, turn it to 0 manually.
