Installing the sauna control unit
To install the sauna control unit, perform the following steps:
1. Screw two chipboard screws (3 x 25 mm) into the wall of the sauna at a height

4.1. Installing the control unit
Observe the following points when installing the sauna control unit:
● The sauna control unit must be installed outside the sauna room or in accord-
ance with the recommendation issued by the sauna manufacturer.
● The ambient temperature must be within a range spanning -10 °C to +40 °C.
● The sensors may only be connected using the sensor leads supplied with the
unit, which are heat-resistant up to 150 °C.
ATTENTION!
Damage to the unit
The sauna controller is resistant to splashing water, but direct contact with water
could still damage it.
● Install the sauna control unit in a dry place at which a maximum humidity of
95% is not exceeded.
The sensor leads may be extended under the following conditions:
● A silicon cable resistant to temperatures up to 150 °C is used.
● The minimum cross-sectional of the cable is 0.5 mm

.
● The heater sensor cables may NOT be longer than 10 m.
ATTENTION!
Interference can impair signal transmission
● Route all sensor cables separately from other mains cables and control cables.
● Protect cables with only one layer of insulation by using a conduit (double
insulation).
