Circuit board connections
The temperature/humidity in the sauna cabin
is set via the control panel. The set values are
checked by sensors and controlled by the relay
box.
The sensors are connected to the RJ10 sensor
jacks using RJ10 plugs.
Each sensor can be connected to any one of
the three jacks. The connected sensors are au-
tomatically detected by the control unit.
If no humidity sensors are used, the humidity is
regulated in proportion to time.
For example, the humidity setting = 40 means
the vaporiser is on approx. 40 % of the total op-
erating time.
This setting does not take into consideration
the actual humidity in the sauna cabin and
makes it possible to consistently produce a
specific volume of steam.
If no humidity sensors are used, the vaporiser
must be set up in relation to the cabin size in
such a way that the limit curve is not exceeded
when there is maximum steam.
The heater sensor (main sensor) controls the
temperature in the sauna cabin. You can im-
prove heat distribution in very large saunas
where air circulation is a challenge by using an
additional bench sensor.
In this case, the heater sensor does not control
the sauna temperature, but acts as a temper-
ature limiter (above approx. 120°C) to prevent
overheating and the triggering of the safety
temperature limiter in the event of a malfunc-
tion.
Here, the bench sensor regulates the tempera-
ture. If the bench sensor fails, the heater sensor
regulates the temperature.
The (optional) humidity sensor regulates the
relative air humidity in %.
At the same time, the control unit attempts to
keep the set humidity as precisely as possible.
The humidity sensor regulates the humidity
according to the following indicated character-
istic curve:
• All values that lie below or on the charac-
teristic curve can be set and used. When
setting a parameter, e.g. temperature, the
setting for the other parameter (humidity)
is automatically adjusted.
• Values that lie above the characteristic
curve cannot be set.
