Installation and connection of the sauna
systems and other electrical equipment
may be undertaken only by a expert; this
is subject to VDE 0100, Part 703/2006-2

1.Installation of the control units
Attention:Itisforbiddentoinstallthecontrol
box in a closed switch cabinet or behind a
wooden panelling!
Before the control unit can be fastened to
theouterwallofthecabin,thecoveringofthe
control unit must be removed. For this, the
dials are pulled from their spindles with a
slight tug, and the two mounting screws
(Illust. 1) are loosened.
These screws are attached beneath the
control panel dials as captive screws, but
may be screwed open and closed through
the visible holes in the operating panel with
a small Phillips screwdriver. After the
screws are loosened, the cover is removed.
For practical purposes, the control unit
should always be fastened to the outer wall
of the cabin, to which the sauna oven inside
the cabin is also attached.
Please observe that most sauna cabins
have already been equipped with cable
condiuts for electrical wiring. In this case,
the position of the control unit is pre-
determined.
The sensorlines (capillary tubes) which as
explained later need to be mounted in the
sauna cabin above the sauna oven, are
roughly 120 cm long.
These capillary tubes cannot be elongated.

equippedfor avoltageof 400V3NACwith
a maximum breaking capacity of 9 kW and
with a safety shutdown as standard.

For the mounting of the control unit, the
mountingholesØ3aredrilledinaccordance
with the dimensions given in Illust. 3, and
oneoftheprovidedwoodscrews4x20, see
Illust. 3.1, is screwed into the wood through
the upper middle hole, leaving a 3mm
section of the screw projecting out from the
wall. The lower part of the control unit is
hooked onto this wood screw by its upper
mounting hole. Finally all connecting lines-
see Illust. 4-are conducted through the
respective feed-through conduits into the
controlunit. Thelowerpartisfinallyfastened
to the cabin wall through the two lower pre-
drilled holes.
If the sauna cabin is not equipped with
cable conduits for the connecting lines,
these lines must be laid directly onto the
cabin wall, where they will be visible. For
this purpose, the three mounting holes
must be pre-drilled, as shown in Illust. 3.
Finally,alignthelowerpartofthecontrolunit
over the drilled holes and sketch the right-
hand feed- through hole for the sensor lines
onto the cabin wall. Drill a roughly 10 mm
feed-through hole at this spot.
Because the connecting lines must be laid
between the control unit and the cabin wall
in this type of installation, for practical
purposesinarecessofthegroovedpanels,
the control unit must be installed in such a
way as to provide for adequate clearance.
For this purpose, 3 spacer tubes are
provided with the control unit. Using these
tubes, the lower part is installed to provide
for this clearance as shown in Illust. 3.2.
After the connecting lines are fed through
the respective feed-through channels into
the control unit, bolt the lower part, again
with help of the spacers, into the lower
mounting holes on the cabin wall.

2. Electrical installation
(see Illust. 5)
The electrical installation may be
undertakenonlybyanauthorizedelectrician
subject to the regulations of the local po-
wer utility company and the VDE.
The 5-wire power supply lead is brought to
the control unit and connected, as can be
seen from Illust. 5. A wiring diagram is
posted in the area of the main terminal.
Install the sauna oven according to the
installation guide in front of the air intake
vent, and drill a roughly 10 mm hole beside
the air intake vent.
Lead the oven connecting cable through
this hole to the outside, install a distribution
boxneartheairintakeventwhichissuitable
for use in wet areas, lay a 5-wire power
supply lead between distibution box and
control unit, connect in the distribution box
with the silicon connecting line in
accordance with the wiring diagram. The
minimum diameter of the connecting line is
shown in the chart below.
Illust.5
When connecting the sauna system, a device which allows the unit to be disconnected from
thepower source with a contactdistanceofat least 3 mm from allterminalsmust be provided.
LS switches, fuses and relays are considered suitable devices for disconnecting the unit.

3. Installation and Operation
3.1 Sensor installation
The thermostatic control unit is equipped
with a thermostat and an overheat safety
shutdown device. Pull the capillary tube
sensors through the afore drilled hole into
the cabin and affix them in the retainer slots
ofthesensorretainerprovided. Thecapillary
lines must not be bent or damaged. The
smallest bending radius should not be
under 3-4 cm.
Usethe providedwood screws tocenter the
sensor mount over the free air exhaust
ventsof the ovenwhichface the cabin door,
25 cm below the cabin ceiling on the cabin
wall in accordance with Illust. 6.
3.2 Startup
Illust.6
The previously described position must be
observed in any case; otherwise, the target
temperatures will not be reached. The
capillary tube lines can be mounted to the
cabin wall with the mounting screws
provided.
The exess length of the capillary tube
sensors should be rolled up und must be
placed into the cabin. Don´t push back the
sensors into the control unit under any
circumstances.
Operation of the sauna system is started
with the left-hand timer switch. The
maximum activation time is 4 hours due to
safety precautions. During this time the
green signal lamp lights up.After 4 hours
the sauna oven and the cabin light will shut
itself down. The cabin temperature is pre-
selectedwiththeright-handthermostatdial.
The total control range is between ca. 70
and 110°C. As soon as the sauna oven
reaches heat mode, the red signal lamp for
"Heating"lightsup. Whenthedesiredsauna
temperature is reached, the heat mode will
be stopped (the signal lamp goes out).

2.1 Installation of the cabin lighting
All electrical installations in the sauna cabin
must be able to withstand surrounding
temperatures of at least 140° C. The
connecting cable must be led through the
previously drilled hole and connecting in
thecontrolunitinaccordancewiththecircuit
diagram.
The sauna lamp must always be mounted
as far as possible fromsite of installation of
thesauna oven. To this end, thesaunawall
opposite the oven or the adjacent corners
may be chosen.

safety shutdown device. The sensor of the
overheat safety shutdown with the sensor
mount is, as previously explained, installed
25 cm below the cabin ceiling on the cabin
wall. Ifthesaunaovendoesnotturnoffafter
reaching the maximum pre-selected
temperature due to a defective control unit,
the safety shutdown mechanism will turn
off the oven before a critical sauna
temperature is reached.
4. Fuse protection of the sauna
lighting
These tasks may only be accomplished
by a expert!
The sauna lighting and the control circuit
are protected by a microfuse in the control
unit. To replace the fuse, the system must
be disconnected from the power source, as
with all tasks on the control unit.
After you have become familiar with the
function of the control unit through this text,
we wish you many relaxing hours in your
sauna!
english
After a safety shutdown of this nature, the
covering of the control unit (see Illust.1 )
must be removed and the red button in the
centerofthecontrolunitactivatedbyaexpert
after disconnection of the system from the
power source using the main switch.
Shouldtheoverheatsafetyshutdowndevice
switch off again during further operation,
the complete sauna system must be
checked by an electrician.
Note
Is there a problem reaching the required
bathing temperature, or is the temperature
different from that indicated on the
thermometer in the cabin?
Please note that the temperature sensor is
positionedintheareaoftheheatingsystem.
The thermometer is always located in a
differentplace(forex.onthebackwallofthe
cabin over the recliner bench). The sensor,
however,canonlymeasurethetemperature
in its immediate vicinity; even differences of
only 25 cm between sensor and
thermometer can lead to temperature
differencesofupto15°C. Inaddition,many
bimetallic strip thermometers react very
sluggishly, so that the actual temperature is
sometimes displayed only after about one
hour. The thermometer should not be
installed with the complete housing surface
flush with the cabin wall but rather with
some clearance in relation to the wall. This
way you will reduce the reaction time.
It is therefore entirely possible that your
thermometer will show a lower value than
the one you have set at the control unit.
5. Safety cutoff
The sauna control unit is equipped with a
temperature limiter for security.
In case of a malfunction this temperature
limiter cuts off all 3 phases by safety
reasons.
Once the temperature limiter has cut off
the current, he must be reset mechanically.
Attention:
Cut off the control unit from the
mains at first.
Open the control unit.
There are 3 control elements visible now.
In the middle is the temperature limiter for
security.
