Please note that an optimal interaction be-
tween sauna cabin, sauna heater and sauna
control unit is mandatory for a pleasant sauna
climate in your cabin. With this high-quality
sauna control unit you can “operate“ your sau-
na system, and thanks to the many individual
programming options, surely you will quickly
nd the setting which suits you best.
Perception in the sauna is very subjective,
therefore, it really requires your own percep-
tion or that of your family to nd the most suit-
able settings.
The control units are supplied with the preset
typical climate values for a classic Finnish sauna
or for models with humidity control, as well as
for a sauna with humidity operation.
The following operating instructions describe
how to pre-select “your“ climate in the cabin.
Read these instructions carefully, so that you
General information about
sauna bathing
Preface
quickly and easily nd your way though the
programming process. Please note the varia-
tion in temperatures in the cabin while sauna
bathing. The hottest area is directly below the
cabin ceiling, whereas there is a steady temper-
ature gradient towards the oor of the cabin.
Inversely, the relative humidity is lowest direct-
ly below the cabin ceiling and the highest by
the cabin oor.
For safety reasons the temperature sensor with
the overheat safety shutdown is located on the
cabin ceiling above the heater, as this is usually
the hottest area in the cabin.
Thus, there will always be temperature varia-
tions between the temperature sensor of the
control unit and the thermometer in the cabin.
For example, when pre-setting the cabin tem-
perature to 100 °C, the thermometer inside the
cabin may show 85 °C - 90 °C. This is in accord-
ance with the typical climate inside the cabin.
Only use sauna-suitable (up to 140 °C temper-
ature-resistant) cabin lights. Always pay atten-
tion to hygiene. Always use hand- or bathing
towels to avoid getting perspiration on the
wood.
For control units with vaporizer connection
(optional), we recommend to reheat or dry the
cabin after each humid operation, in order to
protect your cabin from possible damage due
to the humidity mode. In addition, in poorly
ventilated rooms, a ventilation fan can be used
to remove the used moist air.
To avoid drafts, you should avoid using any
ventilation system while sauna bathing. It
should only be used if recommended by the
cabin manufacturer.
Dear customer,
you have purchased a high-quality electronic
device with which you will enjoy your sauna
& steam bath for many years to come. This
device was designed and inspected according
to the current European safety standards and
manufactured at the factory in accordance with
the quality management standard DIN EN ISO
9001:2015.
This detailed installation and operation manual
has been prepared for your information. Pay
particular attention to the important notes and
the information on electrical connection.
We wish you a restorative and eventful wellness
experience.

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

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).
Install the sauna heater and the vaporizer (if
available) inside the sauna cabin in front of the
air intake according to the manufacturer’s in-
stallation 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
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.

The max. 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.
With the setting “unlimited”, the device must
be switched o manually. This feature is only
allowed in monitored commercial sauna facil-
ities.
In addition, if the control unit is set to “private”,
the heating time is automatically limited to 6
hours.
The type of use has priority.
All control units are delivered (factory set) with
the limitation“6 hours”.
Fan
Only use fans whose speed can be controlled
via phase control.The fan must have the splash-
water protection class (IPx4) and must be resist-
ant to the ambient temperature. The fan can be
mounted anywhere, however never close to
the rising ow of hot air from the heater and
must be positioned as far away as possible from
the installation location of the IR-radiator (must
not be directly illuminated).
!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 nev-
er close to the rising hot air of the heater.
Only dimmable lamps may be used. Observe
max. power! The control unit is factory set to
resistive and inductive light load. It is possible
to dene the light output. Refer to the chapter

Attention! Only connect dimma-
ble lamps!
When connecting non-dimmable lamps, there
is a risk of damage to the lamps– or the control
unit. In this case, the warranty expires.
Requirements for lamps:
• Min. power 5 W
• Ohmic loads max. 100 W
• Dimmable energy-saving lamps max. 35 W
• Lamps on conventional transformers max. 60
VA
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 connec-
tion line should not be overloaded. If neces-
sary, the load (consumer) connected to the
potential free contact should be additionally
protected and provided with a separate po-
wer supply.
