A supply air diffuser is used when the sauna heater’s temperature sensor is placed near the sauna’s supply air valve. The flow of air from the valve cools the air by the time it reaches the temperature sensor, giving an incorrect reading. As a result, the sauna heater may become too hot. The supply air diffuser directs the air away from the sensor.
NOTE: The temperature sensor must always be installed in a place specified in the sauna heater’s instructions!
