Humidity Sensor

Following variants of the humidity sensor are available:
14
I.) Floor-standing- or Wall-mounted heater
Unless a different position is specified by the oven manufacturer, install it on the wall
behind the sauna oven (centre sauna oven), 20 cm below the ceiling.
II.) Underbench heater
1-Sensor-System-U1: Unless a different position is specified by the oven manufac-
turer, install it on the wall behind the sauna oven (centre sauna oven), 20 cm below
the ceiling and additionally install one STB (Safety-Temperature-Limiter) U2 5cm be-
low the grating of the airshaft.
2-Sensor-System-U2: Unless a different position is specified by the oven manufac-
turer, install it on the wall behind the sauna oven (centre sauna oven), 5cm below the
grating of the airshaft.
Install the bench sensor at shoulder height of the topmost bench:
I.) on the opposite side of the oven (S2)
II.) same side, offset to the Underbench oven (U1) or adjacent wall.
This position for the sensor is only a recommendation for standard cabins.
Attention: The system installer has to consider cabin-specific conditions, such as
the position of the steam outlet, the supply and outlet air, the door (s), the shape of
the ceiling, etc., and mount the sensor at the appropriate place for this cabin!.
Install the combined sensor for temperature and humidity like the bench sensor.
Ensure unrestricted air circulation.
Do not install the sensors in the immediate vicinity of the door or a window.
The limiter sensor for the IR system is only required if the manufacturer of the IR
system a maximum temperature for their system dictates, which is smaller than our
room temperature of max. 70°C or limiter temperature of 130°C.
If a sensor is needed, it shall be installed according to specifications of the IR system
manufacturer.
