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.

!
Attention!
If control units with remote control op-
tions* are used, protection against switch-
ing on if the heater is covered is required.
(e.g. cover protection rail type 1-5).
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 (DIN VDE 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 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.
• Always heed the specications and in-
structions of the cabin manufacturer, too.
*Remote control = setting up, controlling or adjust-
ing a unit by a command that can be given out of
view of the unit by means of transfer media such as
telecommunication, audio technology or bus sys-
tems. (this also includes weekly timers)

Cable connection
Use the supplied 5 m connection cable with
RJ10 plug (control panel side) and RJ14 plug
(relay box side).
If necessary this connection line may be ex-
tended to approx. 100 m length. For this you
will need to use a standard coupling RJ14/RJ14
and the extension cable with RJ14 plugs in re-
quired length. The coupling and extension ca-
ble may be purchased from specialist dealers.

Inner sauna wall
Draw the connection cable from the relay box
to the control panel.
The connection cable may be laid only be-
tween the outer sauna wall and insulation layer
to prevent overheating (Fig. 7).
The insulation should ensure that the temper-
ature at the outer sauna wall may not exceed
75° C.
Pay attention to that the bigger plug (RJ14)
shall be oriented towards the relay box and the
smaller plug RJ10 towards control panel.

Control panel
Installation place
The control panel may only be mounted out-
side the sauna cabin. If ductwork is already
provided for electrical installations then the
position of the control unit is predetermined
by that. The control panel is designed for
ush-mounted installation into the sauna wall
or a similar adjacent wall. The installation shall
be carried out as follows.
First of all determine the installation position.
Ideally it should be at the eye sight height, as
shown on g. 5

Use 4 screws appropriate to
the wall material.
Installation of the housing upper part (control panel with display)
Place the control panel directly in front of the housing base and pay attention to the correct orien-
tation (jog-dial switch shall be at the bottom right). Plug in the connection cable with RJ10 plug
which you pulled through the housing base.
Now press the control panel carefully into the housing base until you hear a click sound (hooks of
the upper part should snap into the holders in the base). Make sure the control panel sits reliably
in the base part.
Installation hint: When you lay the connection cable do not pull it too tight, allow some extra
length around the base, so that later you can take the control panel out of the base easily while
still having it connected.
Taking the control panel out
To remove (detach) the control panel use the included deinstallation tool or a suitable athead
screwdriver. Insert the tool or screwdriver into the groove located in the middle of the bottom
side (between housing upper part and housing base) and carefully pull it away from the wall until
control panel is released from the base and may be taken out. Do not apply excessive force as this
may damage the inner holders.

Connection of sensor cables
Do not lay sensor and power supply lines together, or lead them through the same duct. This can
lead to interferences in the electronics, such as“uttering” in the relays. Connect the cable shield-
ing (if present) to ground in the control unit.
Please observe that the following dimensions relate to the values stipulated during the unit in-
spection acc. EN 60335-2-53. The heater sensor must always be installed at the point where the
highest temperatures are to be expected. Fig. 12-14 provide you an overview of the mounting
point of the sensor.
1. Mount the heater sensor in cabins up to 2 x 2 m according to g. 13, in larger cabins according
to g. 14.
2. Drill a hole to lead the cable through, preferably through the middle of one of the wooden
planks.

4. Connect the sensor cable to the sensor board according to g. Make sure the connections are
correct. Connect the limiter cable (2-core white cable) to the limiter board (STB).
5. Mount the sensor to the ceiling plank using two supplied screws and attach the housing
cover.
6. After completed installation and correct commissioning of the control unit, the sensor line for
overheating protection must be tested for proper functioning. Disconnect one of the wires
of the white cable at the STB board in the sensor housing - the respective error message shall
appear on the display. Re-connect the wire to make the error message disappear.

Attention:
Please pay attention that by the installation of the
cable lines for sensors and display panel it is not
permitted to pull the cable by the modular plug.
If you use a help to draw the cable through the
ducts it must not be attached to the plug but to
the cable only!
Pulling the cable by the plug may damage it and
cause loose contacts resulting in malfunction of
the control unit. In such case the warranty will be
void and the cable should be replaced.

Electrical connection
The electrical connections may only be car-
ried out by a certied electrician in compli-
ance with the guidelines of the local power
supply company and applicable legal regu-
lations (e.g. VDE norms for Germany).
In general, there may be only one permanent
connection line to the network. Furthermore
equipment should be provided that makes it
possible to disconnect the system on all phases
from the power supply with a contact gap of
minimum 3 mm.
All electrical installations and all connection
lines that are installed inside the sauna cabin
must be suitable for an ambient temperature
of at least 170 °C.
The power supply line shall be laid to the con-
trol unit and connected to the power input ter-
minals.
The power supply cable shall be laid to the
main relay box and connected to the power
input terminal as per connection diagram (see
wiring diagrams, page 18-19).
Install the sauna heater and the vaporizer in
front of the air intake according to the manu-
facturer’s installation instructions.
Draw the silicone cable through the ductwork
to the relay box and connect it to the appropri-
ate terminals as directed in the wiring diagram.
Make sure to observe the wiring diagrams on
pages 18 - 19 with the corresponding terminal
connection scheme.
Notice: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 covered
to protect it from outside inuences. There-
fore, use a suitable cable-duct or a PVC-pipe
through which you can run the line up to the
power unit.
Special advice for connection of
Bi-O sauna heaters to control unit.

Relay box, lower front cover opened
!
Attention!
By working vaporizer the power output
line„W“ will be diverted to the„Wb“ line
of the vaporizer.
The sauna heater section will then oper-
ate with 2/3 of the total power.
(if no LSG 18 H or LSG 36 H is used)
If a vaporizer is connected and the operation
mode is set to humid operation, then upon
switching the unit on the vaporizer will be
energized for a short time. This allows you to
prove that the vaporizer is functional and op-
erates correctly. It will then switch o until the
temperature reaches 10°C below the target lev-
el and then switch on. This ensures faster heat
up times and prevents that the steam is sup-
plied into a still too cool sauna cabin.

Sauna lamp connection Heating time limitation
LSG
Connection of the power
extension unit
The switching capacity may be extended with
an external power extension unit (LSG), in or-
der to connect and operate the sauna heaters
above 9 kW power.
For connection details please refer to the instal-
lation and operation manual for the respective
LSG model.
The maximal heating time may be limited with
the jumper #5 on the main board of the relay
box. The limitation may be set to 6 hours, 12
hours or to unlimited.
If the control unit has been set to private (do-
mestic) use, then the heating time will be auto-
matically limited to 6 hours.
The jumper setting will override the software
settings.
!The sauna lamp must have the protection
class of at least IPx4 and should be resistant to
the ambient sauna temperatures. The sauna
lamp may be installed at any location but never
close to the rising hot air of the heater.
Only dimmable lamps may be used.The control
unit will detect strongly inductive loads and
will adjust the phase edge control accordingly.
Make sure to observe the specications of the
light output of the control unit for each light
type.
!Notice: By connection of not dimma-
ble lamps there is a risk of damaging either
the illuminant or the control unit. No war-
ranty claims may be accepted in this case.
The terminals „3“ and „4“ on the main board of
the relay box are the terminals of the normal-
ly open (NO) contact of a relay. Both terminals
have no further connection and are therefore
potential-free (voltage free). You can inte-
grate this NO contact into any circuit, in order
to switch an external power load or to relay a
switching signal.The max. load on the potential
free contact, depending on whether AC or DC
shall be switched, is given in the specications
on the page 5.
!
Attention! If you use the terminals L1,
L2 or L3 to power the circuit connected to the
potential free contact, then the connection
line should not be overloaded. If necessary,
the load (consumer) connected to the poten-
tial free contact should be additionally pro-
tected and provided with a separate power
supply.
Potential-free contact
Only use fans whose speed can be control-
led 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).

How to set / change the cabin address
1. Press the programming button > 4-5 sec to
launch the programming mode. The green sta-
tus LED will go out. The red status LED will start
to ash.
2. Press now briey on the button - the ca-
bin address will move to the next va-
lue. The green LED will ash accordin-
gly to indicate the new address number.
For instance, the address has changed from 1 to
2 - green LED ashes two times.
3. Press again on the button to move the address
to the next value as required. In this manner you
can set the addresses 1 to 8.
4. The factory default address is always 1. The rst
press on the button will therefore set the cabin
address 2. The green LED will ash two times
accordingly.
5. After 8 the address wil return back to 1.
6. The programming mode will automatically exit
if you do not press the button for >10 seconds.
The new set address will be saved. The red LED
will go out, the green LED will start to ash
again.
Temperature sensor
Humidity sensor (optional, for H series)
2nd sensor (optional)
The sensors are connected via RJ10 modular
plugs to one of the corresponding sensor bus
RJ10 jacks on the main board of the relay box
as shown on the left. The connection order
may be chosen freely. The sensor bus supports
hot-plugging, sensors may be re-connected
while the control unit is switched on and will be
detected and congured within 2-3 seconds.
The white cable from the overheat protection
fuse in the sensor should be connected to the
2-pin STB connector on the main board.
Do not try to plug the sensors into the sauna
bus connectors (two lower RJ12 jacks), this will
damage the sensor and the main board.
