Dear customer,
with purchase of this sauna control unit you
opted for a superior quality, high-tech elec-
tronic device which was developed and
manufactured according to the highest stan-
dards and guidelines.
Please note that an optimal interaction of
sauna cabin, sauna oven and sauna control
unit is mandatory for a pleasant sauna cli-
mate in your cabin.
With this superior sauna control unit you can
„operate“ your sauna system, and thanks to
the many individual programming settings
you will surely soon find the setting that suits
you best.
Perception in the sauna is very subjective,
therefore it really requires your own percep-
tion, or that of your family to find the most
suitable settings.
By default the finnish sauna is preset to
95°C. For steam operation the values are
set to 60°C and 60% humidity.
The following operation instructions describe
how to pre-select „your“ climate in the cabin.
Read these instructions carefully, so that you
quickly and easily find your way though the
programming process.
Please note the variation in temperatures in
the cabin while sauna bathing. The hottest
area is directly under the cabin ceiling, whe-
reas there is a steady temperature gradient
towards the floor of the cabin. Inversely, the
relative humidity is lowest directly under the
cabin ceiling and the highest on the cabin
floor.
For safety reasons the temperature sensor
with the overheat safety shutdown is located
on the cabin ceiling above the oven, since
this is the hottest area in the cabin.
Therefore there will always be temperature
variations between the temperature sensor
of the control unit and the thermometer in
the cabin.
General information concerning sauna bathing
For the cabin light use only light bulbs. Do
not use fluorescent lamps, energy saving
lamps and gas discharge lamps.
For example, when pre-setting the cabin
temperature to 100°C, the thermometer in-
side the cabin may easily show 85°C - 90°C.
This complies with the typical climate inside
the cabin.
Always observe hygiene. Always use hand-
or bathing towels, to avoid getting perspirati-
on on the wood.
To protect your cabin from possible dama-
ges due to steam operation, we recommend
reheating or drying the cabin after every
steam bath.
In addition, a fan can help to dissipate used
humid air in badly ventilated areas.
To avoid the perception of draft, you should
avoid using any ventilation system while
sauna bathing. It should only be used if re-
commended by the cabin manufacturer
Always make sure no objects are
located on the sauna oven before
starting the heating cycle.

General safety precautions
• his device has not been designed for being
used by persons (including children) that
are physically or mentally handicapped
or have sensory disabilities. Moreover, it
is not allowed to use this device without
sufficient experience and/or knowledge,
unless these persons will be supervised
by persons responsible for their security
or in case they have been instructed how
to use this device.
• 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 ca-
binet or behind a wooden panelling!
• The electrical installation may be done
only by a qualified 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
qualified technician may remove the hou-
sing 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 tempera-
ture setting. The temperature can be held
within operating parameters and a mini-
mal temperature gradient inside the bench
area of the sauna cabin can be achieved
only if unit is assembled correctly.
• 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
breaking capacitor).
• Completely disconnect the control unit
from the electrical circuit, i.e. flip all circuit
breakers or the main circuit breaker during
each installation or repair.
• Please note the safety and installation in-
formation from the sauna oven manufac-
turer.
• Always heed the specifications and in-
structions of the cabin manufacturer, too.
Attention!
Dear customer,
according to the valid regulations, the
electrical connection of the sauna hea-
ter and the control box has to be carried
out through the specialist of an authori-
zed 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 offer the
possibility of external access (GSM-module,
remote button, etc.) or time-delayed swit-
ching (preselection time, weekly timer, or
similar) a trigger guard with covered heating
unit is required. (cover protection type 1-5 or
S-Guard).

Assembly of the control unit
Wall mounting
Mount the control unit outside the sauna
cabin only. The most practical mounting point
would be the wall area onto which the sauna
oven is mounted on the inside, except on the
outside of the cabin. If electrical conduits are
present, mount the control unit accordingly.
To mount the control unit, please follow these
instructions:
Fastening screws Illust. 1
1.Remove the cover of the control unit. Loo-
sen the fastening screws below the cont-
rol panel. If your unit uses control knobs,
remove them. Enlarge the holes for the
electrical cables (Illust. 4) with a sharp kni-
fe. Drill the threaded holes for the inclu-
ded 4 x 20 mm wood screws according to
Illust.s 3 & 3.1.
2.Insert one of the wood screws into the
upper middle hole. This screw will be the
mounting point for the control unit. Make
sure the screw is projecting out about 3
mm. (Illust. 3.2)
3.Hang the control unit onto the 3 mm pro-
jecting screw. Lead the electrical cable
through the holes you enlarged in step 1
and screw the lower part of the housing
onto the cabin wall using the lower threa-
ded holes. (Illust. 4)

Assemble the sauna oven according to the
instructions provided by the manufacturer in
front of the air intake opening.
Lead the silicone wire to the power control
unit through the ducts and connect them to
the corresponding terminals according to cir-
cuit diagram.
Note: If no ducts are available, bore a hole
next to the air inlet opening and pull the sto-
ve wire/s to the outside to lead them to the
corresponding terminals in the control unit.
In order to protect the silicone wire from ex-
ternal impacts it should be covered. There-
fore use a suitable cable duct or a PVC pipe
in which you lead the wire/s to the power
control unit.
Lead the power cord to the control unit and
connect it to the power inlet terminal.
Electrical connection
The electrical connection may only be
done by a qualified electrical technician
under authority of the regulations of the
local power supply company and those
of the VDE.
In general, there can only be one permanent
connection to the power supply network, to
include a device which allows the unit to be
disconnected from the power source with a
contact distance of at least 3 mm from all
terminals.
All electrical installations and connector ca-
bles inside the cabin must be able to with-
stand temperatures up to 170° C.
The sauna lamp must be splashproof (by
Standard IPx4) and resistant to ambient
temperature. The sauna lamp can be moun-
ted anywhere except in the area of the rising
hot air above the oven. Only bulbs should
be used!
Connecting the sauna
oven
Connecting the sauna
lamp
The control unit can detect water deficit if
there is a zero-potential feed at the WM-
input.
To connect the vaporizer, use silicon con-
necting lines 4 x 1,5 mm² as well.
Warning: Always connect
the neutral conductor of the
sauna oven. During steam operation,
one phase of the oven is shut down;
therefore the heating load is no lon-
ger symmetrical. The result is that
the neutral wire is no longer current-
free.

Connecting the sensor lines
ou should not install sensor and power sup-
ply lines together, or lead them through the
same conduit. This can lead to interferences
in the electronics, such as „fluttering“ in the
relays. If it is absolutely necessary to install
them together, or the wire is longer than 3m,
you should use a shielded sensor line such
as the LIYLY-O x 0.5 mm²). Connect the
shielding to mass in the control unit.
Please note that the following measure-
ments are based on values provided by
the unit quality assurance by the European
Standard EN 60335-2-53. In principle, you
must mount the oven sensor where tempe-
ratures are expected to be the highest. Il-
lust. 7 gives you an overview of the moun-
ting point of the sensor..
1. Mount the oven sensor in cabins up to 2
x 2m according to Illust. 7 and 8, in larger
cabins according to Illust. 7 and 9.
2.Drill a hole to lead the cable through, pre-
ferably through the middle of one of the
wooden boards.
3.Lead the sensor cable through the drilled
hole and attach it to the sensor line accor-
ding to Illust. 10.
4. Attach the lines for the shutoff (white) and
the temperature sensor (red) according to
Illust. 11 to the sensor board. Then insert
the sensor board into the housing.
5.After you are finished installing and have
made sure the control unit is functioning
properly, check the line for overheat shut-
off protection for short circuits. To do this,
release one of the white lines in the sensor
housing. The safety relay of the control
unit should now fall; i.e. the heating circuit
should now be interrupted.

The control unit is suitable for the Finnish sauna and humid sauna types of operation.
In the case of Finnish sauna operation, air in the sauna is not given extra humidity. The air
temperature of the sauna can be set between 40 - 115° C.
When operating with humidity, the maximum temperature is limited to 70° C for safety reasons.
The adjustable temperature range is 30 - 70° C. The humidity level can be set between 0
and 100%.

Using the sauna
Finnish sauna operation
Press the button to switch on the sauna
heater. The display alternately shows the

Steam operation
A suitable vaporizer unit up to 3 kW and 230
V AC is required for steam operation. The
control unit „clocks“ the vaporizer based on
the user-set steam level.
Please note: During the activation of the
vaporizer, the oven heats with only two
phases; that is, one of the switch phases is
switched to the vaporizer.
In the case of the symmetrically wired oven
(equal heating power for each phase), one-
third of the heating power of the sauna oven
is consequently switched off. This serves
both to protect the user from excessive
temperatures as well as to limit the switch
capacity to 3 kW per phase.
The humidity level aimed for depends stron-
gly on the configuration of the sauna cabin,
the type of sauna oven used and the
power of the vaporizer. Therefore, it is im-
portant that you find your personal climate
zone. Always choose the temperature first
(from 30 to 60°C) and then the steam level.
Temperature Relative humidity
60°C 50 %
50°C 60 %
40°C 70 %
30°C 80 %
These amounts are reachable, although they
are higher than the amounts actually needed.
Therefore, reduce the amounts after the pre-
heat cycle; to do so, set a lower value using
the program key. Please note that the cabin
temperature is highest under the cabin ceiling,
although the relative humidity is proportionally
The vaporizer is always activated when an
amount between 1 and 100% is shown in the
display. When the display shows 0, please
note that the vaporizer is not activated, but as
with steam operation in general, the maximum
temperature in the cabin is limited to 70°C.
Please note also that the vaporizer starts up
only after the temperature falls to this level.

Modern vaporisers are equipped with
overheating protection in accordance with
the latest technology. When this is activated,
e.g. when there is not enough water in the
vaporiser tray (low water)
the control unit switches itself off after 2
minutes for reasons of safety. The fault mes-
sage opposite appears in the display.
Note: On some vaporisers a buzzer on the
sauna heater gives an additional warning
when the vaporiser’s thermostat is activated
in case of low water.
Press the button to delete the fault mes-
sage. When the sauna heater has cooled
down, or when you have topped up the
water, you can use your sauna again
as normal.
Be careful when adding
water. Only use hot water. As
the heating rod is hot this may produce
a lot of steam, which could result in
scalds

Changing the temperature
In the following one we show, how you can stop the temperature of the Sauna your desires
accordingly. Please take into consideration that these values can vary by a few degrees,
depending on cabin configuration. For safety reasons the temperature is measured in the
hottest area of the cabin above the oven. This temperature serves as a value for the tempe-
rature around the sauna benches. Depending on oven capacity and placement of the fresh
air vents, undesirable influences can alter these measurements, not allowing the maximum
temperature to be reached. The control range is laid out so that normal temperatures in the
bench area can be preselected.
Changing the preset parameters
In order to change the preset parameters for temperature and humidity level, the
sauna must be switched off.
If no input is made for more than 10 secs. during programming, the unit automatically
switches back to its resting state without saving the modified values
Option 1:
