Installation location: The bench sensor is
fi xed to the ceiling of the rear reclining bench
as described for the installation of the heater
sensor.
When the sensor is connected correctly, the
control unit automatically recognises the
sensor once the mains voltage has been
switched on again..
The bench sensor is connected via a 2-wire silico-
ne cable on the control unit to the terminals on the
right-hand side of the lower board. The terminals
are marked „Temp.-Sensor Nr. 2“.
Bench sensor
If there is a problem with the bench sensor, a
fault message will appear:
E 103 = Interruption bench sensor
or
E 104 = Short-circuit bench sensor
In this case, the sensor must be checked by
an expert and replaced if necessary. At room
temperature, the sensor has approx. 2 kΩ.
After disassembly the bench sensor can be
deactivated so that you can use your sauna
despite the problem. See the ‚Bench sensor‘
chapter for more details.
Once the problem has been solved, the
control unit recognises the sensor once the
mains voltage has been switched on again.
