● Lay the heater sensor wires separately from other mains wires and con-
trol wires.
● Protect wires with only one layer of insulation by using a pipe (double insulation).
The heater sensor wires may only be extended under the following
conditions:
● When a silicon wire resistant to temperatures up to 150 °C is used.
● The minimum cross-section of the wire totals 0.5 mm
● The length of the heater sensor wires may NOT exceed 10 m.
1. Lay the two 2-pin heater sensor wires 5 in the wall of the sauna cabin,
lead them to the heater sensor installation location 4, and secure the
heater sensor wires using wire clips.
2. Pull the two half-shells 1 of the heater sensor apart.
3. Connect the four connectors for the heater sensor wire in accordance
with the connection diagram (Fig. 3).
4. Carry out the tests as shown in section 4.5. Installing a door monitor

the two cross-head screws 3 (9 mm).
7. Check whether the heater sensor has been tightly closed.
