Dear customer
You have purchased a high-quality technical
device with which you will have years of sauna
fun. This sauna control unit was designed and
inspected according to the current European
safety standards and manufactured at the facto-
ry in accordance with the quality management
standard DIN EN ISO 9001:2000.
This detailed installation and operation manual
has been prepared for your information. Please
observe in particular the important notes and
the information on electrical connection.
We wishyouexhilaratingrecreational experience
and lots of fun with your sauna!
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!
Compliance of the standard operation, mainte-
nance and repair conditions is also an element
of appropriate use.
The manufacturer cannot be held liable for
deviating, unauthorized alterations and any re-
sulting damages: the initiator of these changes
bears the full risk.
General information
Please check whether the unit has arrived in per-
fect condition. Any transport damages should be
immediately reported to the freight forwarder
delivering the goods or you should contact the
company that shipped the goods.
Please note that you will only be able to achieve
an optimum sauna climate if the cabin with its air
intake and ventilation, the sauna heater and the
control unit are aligned to each other.
Please observe the information and stipulations
made by your sauna supplier.
Sauna heaters heat up your sauna cabin using
heated convective air. Here, fresh air is drawn
in from the air intake which, when heated, rises
upwards (convection) and is then circulated
within the cabin. Part of the used air is pushed
out through the vent in the cabin.This creates a
typical sauna climate which can achieve tempe-
ratures of approx. 110°C measured directly under
the ceiling of your sauna, dropping in tempera-
ture to approx. 30-40°C towards the oor. It is
therefore not unusual to measure temperatures
of 110°C on the temperature sensor hanging
over the heater, whilst the thermometer hanging
on the sauna wall, approx. 20-25 cm under the
cabin ceiling, only indicates 85°C. The bathing
temperature generally lies between 80°C and
90°C in the area of the upper bench when the
temperature is set to maximum.
Please note that the highest temperatures are
always generated over the sauna heater and that
the temperature sensor and the safety limiter
must be mounted there in accordance with the
control unit installation instructions.
When heating up for the first time, you may
notice a slight smell caused by evaporating
lubricants used in production processes. Please
ventilate your cabin before beginning your
sauna bath.

General safety precautions
This device can be used by children aged 8
upwards and by persons with physical,
sensory, or mental disabilities, or who
have inadequate experience and knowl-
edge 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 are to be supervised in order to
make sure that they do not play with this
device.
Attention: It is forbidden to install the
control box in a closed switch cabinet or
behind a wooden panelling!
The electrical installation may be done only
by a qualied electrical technician.
You must comply with the regulations of
your power supply company and applica-
ble VDE regulations (DINVDE 0100).
WARNING: Never attempt repairs or
installations yourself, as this could result
in serious injury or death. Only a qualied
technician may remove the housing cover.
Please note the dimensions in the assembly
instructions, especially when installing
the temperature sensor. The temperature
above the oven is critical for the temper-
ature setting. The temperature can be
held within operating parameters and
a minimal temperature gradient inside
the bench area of the sauna cabin can be
achieved only if unit is assembled correct-
ly.
The device may only be used as intended as a
control unit for sauna ovens up to 9 kW (up
to 36 kW when combined with a contactor
box).
Completely disconnect the control unit from
the electrical circuit, i.e. ip all circuit
breakers or the main circuit breaker during
each installation or repair.
Please note the safety and installation infor-
mation from the sauna oven manufactur-
er.
Always heed the specications and instruc-
tions of the cabin manufacturer, too.

Attention!
Dear customer,
according to the valid regulations, the
electrical connection of the sauna heat-
er and the control box has to be carried
out through the specialist of an author-
ized electric shop
We would like to mention to the fact
that in case of a warrenty claim, you
are kindly requested to present a copy
of the invoice of the executive electric
shop.
When using control units that
oer the possibility of external access
(GSM-module, remote button, etc.) or
time-delayed switching (preselection
time, weekly timer, or similar) a trig-
ger guard with covered heating unit is
required. (cover protection type 1-5 or
S-Guard).

Installation of the control unit
Wall installation
The control unit may only be mounted outside
the sauna cabin. It is advisable to select the out-
side wall of the cabin to which the sauna heater
is xed from the inside as mounting position. If
ductwork is already provided for electrical in-
stallations then the position of the control unit
is predetermined by that. Please follow the in-
structions for installation:

Connection of the sensor cables
You should not lay sensor and power supply ca-
bles together, or draw them through the same
feedthrough. This can lead to interferences in
the electronics, such as“uttering”in the relays,
which may damage the control unit. If it is nec-
essary to lay the cables down together, or if the
line is longer than 3 m, use a shielded sensor
cable (4 x 0.5 mm²).
Connect the shielding to ground in the control
unit.
Please observe that the following dimensions
relate to the values stipulated during the unit
approval as per norm EN 60335-2-53. The heat-
er sensor must always be installed at the point
where the highest temperatures are to be ex-
pected. Illust. 7 - 9 give you an overview of the
mounting point of the sensor.
1. Mount the oven sensor in cabins up to 2 x 2m
according to Fig. 7 and 8, in larger cabins ac-
cording to Fig. 7 and 9.

By faults of the second sensor the following er-
ror messages will be displayed:
„Sensor break“ - interruption of the sensor cir-
cuit (e.g. faulty contact).
or
„Sensor short“ - short circuit of the sensor
In this case, the sensor must be checked by a
specialist and replaced if necessary. At room
temperature 20 °C, the sensor has approx. 2 kΩ
resistance.
In order to keep on operating your sauna cabin
despite the second sensor fault switch the unit
from power supply, disconnect the cable con-
nection to the second sensor and restore the
power supply.
Once the problem has been solved, the control
unit shall recognise the sensor after it has been
re-connected and the mains voltage has been
switched on again
The bench sensor is connected with a 2-core
silicone cable from the sensor pcb to the termi-
nals on the right-hand side of the main board
of the sauna controller (X2), as shown below.

Electrical connections
The electrical connection may only be done
by a certied electrician in compliance with
the guidelines of the local utility company
and the VDE.
In general, there may be only one xed connec-
tion to the network; therefore equipment should
be provided that makes it possible to disconnect
the system with all poles from the network with
a contact opening width of minimum 3 mm.
All electrical installations and all connection
lines that are installed inside the cabin must
be suitable for an ambient temperature of at
least 170 °C.
The power supply line is run to the load control
unitandconnected tothepowerinputterminals.
Install the sauna heater and the vaporizer in front
of the air intake according to the manufacturer’s
installation instructions.
Run the silicone line through the ductwork to
the power unit and connect it to the appropri-
ate terminals as directed in the wiring diagram.
Note: In case there is no ductwork available drill
a hole next to the air intake opening and run the
heater line through this hole to the outside and
to the appropriate terminals in the control unit.
The silicone line must be buried to protect it
from outside inuences. Therefore, use a suitable
cable-duct or a PVC-pipe through which you can
run the line up to the power unit.
Connecting the sauna
heater
Thesaunalampmustbe weatherproofprotected
(IPx4) and resistant to the ambient temperature.
The sauna lamp may be installed at any location
but never in the vicinity of the rising hot air of
the heater.
Connecting the sauna lamp
To connect the vaporizer, use silicone connect-
ing lines 4 x 1,5 mm² as well.
Connecting the vaporizer
The control unit can detect water decit if there
is a zero-potential feed at the WM-input.
Connecting a fan
The fan must be weatherproof protected (IPx4)
and resistant to the ambient temperature.
The fan can be mounted at any point, but never
near to rising hot air from the heater and as far
as possible from the installation position of the
