Installation of the optio-
nal second temperature
sensor (bench sensor)
Installation place:
The bench sensor shall be
mounted to the ceiling over the rear wall bench
opposite to the heater as described in the in-
stallation of the bench sensor.
If the sensor is connected correctly, the control
unit shall automatically recognise it once the
mains voltage has been switched on again.

By faults of the second sensor the following er-
ror messages will be displayed:
„Sensor break“
- interruption of the sensor cir-
cuit (e.g. faulty contact).
or
„Sensor short“
- short circuit of the sensor
In this case, the sensor must be checked by a
specialist and replaced if necessary. At room
temperature 20 °C, the sensor has approx. 2 kΩ
resistance.
In order to keep on operating your sauna cabin
despite the second sensor fault switch the unit
from power supply, disconnect the cable con-
nection to the second sensor and restore the
power supply.
Once the problem has been solved, the control
unit shall recognise the sensor after it has been
re-connected and the mains voltage has been
switched on again
The bench sensor is connected with a 2-core
silicone cable from the sensor pcb to the termi-
nals on the right-hand side of the main board
of the sauna controller (X2), as shown below.
