Dear customer,
On purchasing this control unit, you have ac-
quired a high-quality device that was devel-
oped and manufactured in compliance with
the latest standards and quality guidelines.
Please note that perfect interaction of the
steam bath cabin, the steam generator and
control unit must be guaranteed to achieve the
typical pleasant steam bath atmosphere in your
cabin. This high-quality control unit is used to
'operate' your steam bath system; its many pro-
gramming options allow you to quickly nd the
settings that best suit your requirements.
Everybody experiences the climate in
the steam bath dierently, which is
why you need to nd your own indi-
vidual settings, or those of your family.
The following operation instructions de-
scribe how to pre-select "your" climate in
the cabin. Read these instructions careful-
ly, so that you can quickly and easily nd
your way though the programming process.
Please note that there are dierent tempera-
tures in the cabin of your steam bath.
Therefore there will always be temperature var-
iations between the control unit temperature
sensor and the thermometer in the cabin.
For instance, a pre-selected temperature of 50
°C may show a value of 38°C on your display
thermometer. This would then also correspond
to the typical climate data in the cabinet.
Only use suitable cabin lights. Always ensure
hygienic conditions.
To prevent draughts inside the cabin, try to
avoid using the fan function during your steam
bath. It should only be used if recommended
by the cabin manufacturer.

• This device can be used by children aged
8 upwards and by persons with physical,
sensory, or mental disabilities, or persons
who have inadequate experience and
knowledge if they are supervised or if they
have received adequate instruction in how
to use the device safely and understand
the associated risks. Children may not play
with this device. Children may not clean
or carry out any user maintenance if un-
supervised.
• Children should be supervised to ensure
that they do not play with the device.
• Caution: The unit may not be in-
stalled in closed switch cabinets or behind
closed wooden panels!
• Only qualied electricians may install the
device.
• You must comply with the regulations of
your electrical supplier and applicable VDE
regulations (DIN VDE 0100).
• Caution, risk of fatal injuries: Nev-
er carry out repairs or installation work
yourself. Only a qualied technician may
remove the housing cover.
• Please always observe the dimensions
stated in the assembly instructions when

served if the assembly work is carried out
correctly, and there is a very low tempera-
ture uctuation in the steam cabin.
• The unit may only be used as intended as
a control unit for steam generators up to
9 kW. Control units where there is the op-
tion of increasing the switching capacity
in combination with a power switching
unit can be used up to 36 kW.
• The system must be completely discon-
nected from the mains supply before car-
rying out any installation work or repairs,
i.e. switch o fuses and master switch.
• Observe the safety and installation infor-
mation provided by the manufacturer of
the unit.
• Please also observe the information and
instructions provided by the cabin manu-
facturer.

this screw. Therefore, leave the screw out by
approx. 3 mm (Fig. 3.2).
3. Hook the control unit onto the 3 mm pro-
truding screw in the upper mounting hole.
Insert the supplied rubber grommets into
the openings at the rear wall of the housing
and insert the connecting cable through
these openings.
Remove the control device cover. In order to do
this loosen the screw at the top of the housing
and pull the housing top upward while swivel-
ling (Fig. 1).

Temperature sensor installation
Do not install sensor and power supply lines together, or lead them through the same duct. Install-
ing these together may lead to malfunctions in the electronics, e.g. error messages.
Any cable shielding (if any) must be connected to the earth in the control unit.
Please note that the following information about sensor position provides only a guideline for
the optimal climate and temperature regulation in a standard cabin. Sensor position may vary
depending on the cabin situation. Fig. 8-10 provide an overview of the sensor installation.

Optimal position is normally
opposite to the steam out-
let with approx 2 m gap at
some 16-170 cm from the
oor level.
Notice: a too small or too
large gap may lead to incor-
rect temperature control.
Depending on the cabin
situation individual testing
may be required.
Make sure that the sensor
sticks to 30 mm out of the
cabin wall as per g. 10.

Electrical connections
In general, there may be only one xed connec-
tion to the power supply. Equipment should be
provided that makes it possible to disconnect
the system with all poles from the power sup-
ply with at least 3 mm contact opening.
All electrical installations and all connection
lines that are installed inside the cabin must
be suitable for an ambient temperature and
should have the adequate humidity protection
class.
The power supply line should be drawn to the
control unit and connected to the connection
terminals as per wiring diagram.
The steam generator should be mounted out-
side steam room as per installation instruction
of the manufacturer / supplier.
Draw the connecting cable and make electrical
connections as per wiring diagram.
Make sure to observe specic connection
details as per wiring diagram for steam gen-
erator and control unit.
The general connections overview is shown
on page 13.
Steam generator connection
Cabin light connection
Heating time limitation
The heating time may limited with the jumper
5 on the main board to max. 6 hours, 12 hours
or it may be set to unlimited time.
By jumper setting „unlimited“ the heating
should be switched o manually.
Default setting from factory is “6 hours”.
!This setting is only allowed if the control
unit is switched o from power supply. Do not
set the jumper by working control unit!
Connect the cabin lamp as per wiring diagram.
!The lamp should have at least IPX6 pro-
tection class and should be suitable to the
steam room temperature range.
The lamp may be mounted at any place except
within the direct range of the steam ow com-
ing out or rising from the steam outlet.
Extractor fan connection
Dosing pump connection
Connect the fan as per wiring diagram.
The extractor fan should have at least IPx6 pro-
tection class. The fan should not be mounted
inside the steam cabin.
Recommended position of the fan is in the
duct channel for air extraction leading from
the cabin.
Notice: The position of the duct vent may have
an inuence on the temperature regulation if
the fan is operated during steam production.
Connect the dosing pump as per wiring dia-
gram shown on pages 13 and 14.
Make sure to observe the maximum allowed
power of the dosing pump.
Pay especial attention to the correct installa-
tion and connection of the dosing line to the
steam pipe.
!Attention!
Do not attempt to install or repair the unit
by yourselves. The unit’s housing may be
opened only by authorized and appropri-
ately qualied electrician. Danger to life!
!Attention!
The electrical connection may be carried
out only by a qualied electrician with
respect to the applicable local norms and

Heating time limitation
The heating time limitation can be adjusted with the JP5 jumper position on the main board of
the control unit. You can set the limitation to 6 hours, 12 hours or set the heating time to unlimited
(manual) mode. The JP5 jumper is located in the middle at the upper edge of the board. You will
need tweezers or an alike tool to change the jumper position. Alternatively you can also take the
board out of the housing slightly (undo the mounting screws in the corners).
If set to unlimited position („24“) with the heating time can be progrmmed up to 23:59 or also set
to„--:--“ position. The setting“--:--”means unlimited heating time. In such case the heating will
not stop automatically and needs to be stopped manually.
