Intended use This sauna control unit is exclusively intended for the control of the sauna heater in a sauna cabin. Any other use over and above the intended purpose is not considered as appropriate use! Com- pliance of the standard operation, maintenance and repair conditions is also an element of appro- priate use.
Installation of the control unit Fasten the housing bottom at the two bot- tom openings (Fig. 4) firmly to the cabin wall. Wall installation The control unit may only be mounted outside the cabin. For sauna rooms it is advisable to se- ca.
Recessed installation 1. Cut out a wall section that is at least 3.5 cm deep according to the dimension in Fig. 5. 21 cm Fig. 5 Insert the supplied rubber grommets into the openings at the rear wall of the housing and insert the connecting cables through these openings.
Connecting the sensor cables You should not install sensor and power supply 20 cm lines together, or lead them through the same feedthrough. This can lead to interferences in the electronics, such as "fluttering" in the re- lays. If it is necessary to lay the cables down together, or if the line is longer than 3m, use a shielded sensor cable (4 x 0.5 mm²).

The menu language All other functions, including the basic setup, must be selected every time before use.
Manual setup of the light type On delivery, the light output is set to inductive loads. The control unit supports resistive, inductive or capacitive loads at the light output and can be adjusted accordingly. Note: Automatic detection is not active. It can be selected manually. If there are problems with the automatic detection, the phase edge control can be determined manually.
Heating time limitation The maximal heating time may be set with a jumper on the display printed circuit board to 6 or 12 hours or to unlimited operation time. The jumper is located at the top edge of the board as shown below.
Device fuses The control unit is fitted with two protective fuses which are mounted on the main relay board of the unit. These fuses protect the electronics on the board and the light and fan outputs. Notice: fuses do not mean absolute protection, in an unlikely case of a power surge or a short circuit with particularly fast voltage increase the electronic components may be still be affected.
Error messages The control unit continuously monitors the sensor for short circuits and interruptions. At the same time, the system checks to ensure that there is enough water in the vaporizer tank. The error messages appear as follows: Display Cause Remedy 12:00 = interrupted room sensor circuit...
