The sensor must be placed exactly as prescribed in the instruction manual in order to ensure that the heater works correctly.
Please note! The supply air vent of the sauna must not be near the temperature sensor. The air stream near the vent will cool the sensor, resulting in the sensor sending erroneous temperature information to the control unit. This may cause the heater to overheat. Minimum distance between the supply air vent and the temperature sensor:
non-directional vent: 1,000 mm
vent directed away from the sensor: 500 mm
If the minimum distance cannot be adhered to, the ventilation system must be altered.
