Connection of the sensor cables
You should not lay sensor and power supply ca-
bles together, or draw them through the same
feedthrough. This can lead to interferences in
the electronics, such as “fl uttering” in the relays,
which may damage the control unit. If it is nec-
essary to lay the cables down together, or if the
line is longer than 3 m, use a shielded sensor
cable (4 x 0.5 mm²).
Connect the shielding to ground in the control
unit.
Please observe that the following dimensions
relate to the values stipulated during the unit
approval as per norm EN 60335-2-53. The heat-
er sensor must always be installed at the point
where the highest temperatures are to be ex-
pected. Illust. 7 - 9 give you an overview of the
mounting point of the sensor.
1. Mount the oven sensor in cabins up to 2 x 2m
according to Fig. 7 and 9, in larger cabins ac-
cording to Fig. 8 and 9.

2. Drill a hole in sauna ceiling panel to lead the
cable through, preferably through the mid-
dle of one of the wooden boards.
3. Lead the sensor cable through the drilled
hole and connect it to the sensor line accord-
ing to Fig. 10.
4. The cables for the limiter fuse (white) and the
temperature sensor (red) shall be connected
to the sensor circuit board as per Fig. 10. In-
sert the sensor board into the casing.
5. Lead the sensor cables through the right-
hand cable intake into the control unit. Lay
the sensor cables inside the control unit as
shown in Fig. 11. Connect the sensor cables
to the board as shown in Fig. 12. In order
to do this, pull the plug
X2
from the circuit
board and plug it back in after the connec-
tion of the sensor.
