Preface
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.
General information about
sauna bathing
Please note that an optimal interaction between 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 sauna 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 perception or that of your family to nd the most suitable 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
quickly and easily nd your way though the
programming process. Please note the variation in temperatures in the cabin while sauna
bathing. The hottest area is directly below the
cabin ceiling, whereas there is a steady temperature gradient towards the oor of the cabin.
Inversely, the relative humidity is lowest directly 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 variations between the temperature sensor of the
control unit and the thermometer in the cabin.
For example, when pre-setting the cabin temperature to 100 °C, the thermometer inside the
cabin may show 85 °C - 90 °C. This is in accordance with the typical climate inside the cabin.
Only use sauna-suitable (up to 140 °C temperature-resistant) cabin lights. Always pay attention 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.

General safety precautions
• This device may be used by children (age
8 and above) and by persons with reduced
physical, sensory, or mental disabilities, or
inadequate experience and knowledge,
if they are supervised or if they have received adequate instructions in how to
use the device safely and understand the
associated risks.
• Children must be supervised to ensure
they do not play with the unit.
• Children and persons who have not re-
ceived proper instruction must not clean
or service the system.
• ATTENTION: It is forbidden to install
the control box in a closed switch cabinet
or behind a wooden panelling!
• The electrical installation may only be
done by a qualied electrical technician.
• You must comply with the regulations of
your power supply company and applicable VDE regulations (DIN VDE 0100).
• WARNING: Never attempt repairs or
installations yourself, as this could result
in serious injury or death. Only a qualied
technician may remove the housing cover.
• Please note the dimensions in the instal-
lation instructions, especially when installing the temperature sensor. The temperature above the heater is critical for the
temperature setting. The temperature can
be held within operating parameters and
a minimal deviation at the bench level of
the sauna cabin can be achieved only if the
device is installed correctly.
• The device may only be used as intended
as a control unit for sauna heaters up to 9
kW (up to 36 kW when combined with a
power extension unit).
• 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 heater manufacturer.
• Make sure to observe the specications
and instructions of the sauna cabin manufacturer.
• ATTENTION: For control units with
remote control functions*, a protection
against switching on if the heater is covered is required. (use the suitable cover
protection rail or another safety device).
*Remote control = setting up, controlling or adjusting 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
systems, this also includes weekly timers. (from EN
60335-1)

When designing the sauna cabin, en-
sure that the external exposed glass surfaces
may only reach a maximum temperature of
76 °C. If necessary, protective features need
to be tted.
Inspect the sauna cabin before each
use! In particular, ensure that no objects
have been stored on the sauna heater or the
IR-radiator, if applicable. Risk of re!
Attention!
Dear customer,
according to the valid regulations, the
electrical connection of the sauna heater
and the control box has to be carried out
through the specialist of an authorized
electric shop
We would like to draw your attention that
in case of a warranty claim, you are kindly
requested to present a copy of the invoice
of the executive electric shop.
Attention!
Only the original spare parts may be used.
Any modication of the cables included in
the delivery can lead to malfunctions and
is not permitted.
Any unauthorized technical alteration
makes the product warranty void.

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, maintenance and repair conditions is also an element of appropriate use.
The manufacturer cannot be held liable for deviating, unauthorized alterations and any resulting
damages: the initiator of these changes bears the full risk.
Important note!
The device must be protected against the adverse weather conditions. It must not be used

electrical installations then the position of the
control unit is predetermined by that. Please
follow the instructions for installation:
Fasten the housing bottom at the two bot-
tom openings (Fig. 4) rmly to the cabin wall.
