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 wish you exhilarating recreational 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 temper-
atures of approx. 110°C measured directly under
the ceiling of your sauna, dropping in temper-
ature 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.

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 assem-
bly 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
information from the sauna oven manu-
facturer.

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:

Connecting the sensor cables
You should not install sensor and power supply
lines together, or lead them through the same
feedthrough. This can lead to interferences in
the electronics, such as "uttering" 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).
Connect the shielding to ground in the control
unit.
Please note that the following dimensional
information refers to values dened by the de-
vice test in compliance with EN 60335-2-53.The
stove sensor always needs to be mounted at
the place where the highest temperatures are
expected. Fig. 7 - 9 provide an overview of the
sensor assembly position, unless the position is
dened in the user manual for the stove.
1. The stove sensor is mounted in cabins up to 2
x 2 m in size as shown in Fig. 7 and 8; in larger
cabins it is mounted as shown in Fig. 7 and 9.

Installing the optional
bench sensor 13
Assembly site: The bench sensor (2nd tempe-
rature sensor) is attached to the ceiling above
the rear bench opposite the stove, as described
in the instructions for the assembly of the stove
sensor.
When the sensor is connected correctly, the
control unit recognises the sensor automatical-
ly after the mains supply has been switched on
again.
Bench sensor
The following error message appears if there is
a bench sensor malfunction:
"Broken bench sensor" - interruption of the
connection in or to the sensor
or
"Short circuit bench sensor" - short circuit of
the sensor
In this case, arrange for a specialist to check or
possibly replace the sensor. The sensor has a re-
sistance of approx 1.9 kW at 20 °C.
To be able to continue using your sauna even
though the bench sensor is faulty, the bench
sensor can be deactivated by disconnecting
the connection and the device receives power
again from the mains supply after being shut
down.
Once the malfunction has been rectied, the
control unit recognises the sensor again after
the mains supply has been switched on again.
The bench sensor is connected to the control
unit via a 2-wire silicon line on the terminal on
the right-hand side of the board (see gure).

Electrical connection
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 suita-
ble for an ambient temperature of at least 170 °C.
The power supply line is run to the control unit
and connected to the power input terminals.
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 appropriate
terminals as directed in the wiring diagram.
Note: If there are no empty tubes, drill a hole
next to the vent inlet opening and feed the stove
supply line(s) to the outside through this hole
to the respective terminals on the control unit.
The silicon line needs to be hidden to protect it
from external inuences.Therefore use a suitable
cable duct or a PVC tube to guide the line to the
load unit.
Connecting the sauna
heater
Connecting the sauna lamp
Connecting a fan
Only use fans whose speed can be
controlled via phase control. The fan
must have the splashwater protection
class (IPx4) and must be resistant to the ambient
temperature.The fan can be mounted anywhere,
however never close to the rising ow of hot air
from the stove and must be positioned as far
away as possible from the IR spot (it may not be
in the light path of the spot).
LSG
Connecting a load switch
(LSG)
For more details, please refer to the assembly
instructions of the power switching device (LSG).
Only use dimmable lighting and bal-
lasts, because otherwise the lights or
the control unit may become damage.
The type of light is recognised automatically, but
it can also be dened manually. (See paragraph
"Manual denition of the lighting") The sauna
light must correspond to the splashwater pro-
tection class (IPx4) and must be resistant to the
ambient temperature. The sauna light can be
mounted anywhere, however never close to the
rising ow of hot air from the stove.
Assembly of a remote start mo-
dule
Then insert the sauna bus cable enclosed with
the remote start module into the designated
sauna bus connection. The other end is inserted
into the respective socket in the remote start
module. Now mount the remote start module
as shown in the enclosed instructions.
