1.3 General safety precautions
lAttention: It is forbidden to install the
control box in a closed switch cabinet or
behind a wooden panelling!
lThe electrical installation may be done
only by a qualified electrical technician.
lYou must comply with the regulations of
your electrical supplier and applicable
VDE regulations (DIN VDE 0100).
lWARNING: Never attempt repairs or
installations yourself, as this could result
in serious injury. Only a qualified
technician may remove the housing
cover.
lPlease note the dimensions in the
assembly instructions, especially when
installing the temperature sensor. The
temperature above the oven is critical for
the temperature setting. The
temperature can be held within operating
parameters and a minimal temperature
gradient inside the sauna cabin can be
achieved only if unit is assembled
correctly.
lThedevice may onlybe used asintended
as a control unit for sauna ovens up to 9
kW. (Up to 36 kW when combined with a
breaking capacitor).
lCompletely disconnect the control unit
fromthe electricalcircuit, i.e. flipall circuit
breakers or the main circuit breaker
during installation or repair.
lPlease note the safety and installation
information from the sauna oven
manufacturer.
2. Assembly of the control unit
2.1 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:
1. Remove the cover of the control unit.
Loosen the fastening screws below the
control panel. If your unit uses control
knobs, remove them. Enlarge the holes
for the electrical cables (Illust. 4) with a
sharp knife. Drill the threaded holes for
the included 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
projecting 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 threaded holes. (Illust. 4)

Please note:
If the sauna cabin is not equipped with
electrical conduits, the electrical cables
mustbe leadalong the outsideof thecabin,
preferably in one of the recesses between
the wood boards. Therefore, you have to
mount the control unit farther away from
the cabin wall, so you can lead the cables
into the unit. In this case, use the included
spacer tubes as shown in Illust. 3.3

In general, there can only be one perma-
nentconnectiontothepowersupplynetwork,
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
cables inside the cabin must be able to
withstand temperatures up to 140°C.
Please use the table below to determine
the required cable diameters for this task.
Attach the power supply lead wire as shown
in Illust. 5 to the power supply terminals of
the control unit. Connection instructions are
printed directly in the control unit.
Warning: Always connect the sauna
oven's neutral conductor. During
steam operation one of the phases
shutsdown,therefore the heat doesn't
spread evenly. In consequence the
neutral conductor becomes
energized.
2.2.1 Connecting the sauna oven
Assemble the sauna oven and the
vaporizer according to the instructions
provided by the manufacturer in front of the
air intake opening. Lead the silicon lines
and electrical conduits to their respective
terminals on the control unit and connect
them according to the circuit diagram
printed there.
Please note: If no electrical conduits are
present, drill a hole with a diameter of 10
mm next to the air intake opening and lead
the oven control cables through this hole
to their corresponding terminals (U V W) in
the control unit. To protect the silicon lines
from external influences, install them in a
shielded fashion. For this task, use a fitting
cable or simple PVC conduit and lead the
silicon cable through it to the control unit.
2.2.2 Connecting the vaporizer
To connect the vaporizer, use silicon
connecting lines 4 x 1,5 mm2as well.

Please note that the following
measurements are based on values
provided by the unit quality assurance by
the European Standard EN 60335-53-2. In
principle, you must mount the oven sensor
where temperatures are the highest. Illust.
7 gives you an overview of the mounting
point of the sensor.
Warning: When connecting the vaporizer
make sure it is correctly attached to the
water bath (WB) and low water shutoff
(WM). If you switch these connections, you
disable the water deficiency function and
bypass the thermostat. As a result, the
vaporizer will overheat.
This is a fire hazard!!
Illust. 6 shows the circuit diagram. The
control unit can detect water deficit if there
is a zero-potential feed at the WM-input.
Illust. 6
2.2.3 Connecting the sauna lamp
The sauna lamp must be splashproof (by
Standard IP54) and suitable for
temperatures up to 140°C. The sauna
lamp can be mounted anywhere except in
thearea of therising hot airabove the oven.
2.3 Connecting the sensor lines
You should not install sensor and power
supply lines together, or lead them through
the same conduit. This can lead to
interferences in the electronics, such as
"fluttering" in the switch protectors. 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 (4 x 05, mm²). Connect the
shielding to mass in the control unit.

3. Operation
The control unit is intended for two
operational modes:
- Dry (Finnish) sauna
- Steam sauna
In the dry (Finnish) sauna mode the sauna
air is not steamed additionally. The sauna
air temperature can be set up to 110°C.
During steam operation the maximum
temperature is limited to 65°C for safety
reasons.
The configuration of the operation
elements are shown in Illust. 12.

3.1 Startup of dry (Finnish) sauna
operation
Switch the sauna oven with the left hand
dial to À operation, i.e. one of the switch
positions with the symbol.
The green LED above the button will light
up. Depending on the current temperature
in the sauna cabin, the sauna oven's red
operational display Åwill light up, signaling
the oven is heating.
Use the right hand dial Á to set the desired
cabin temperature. For a higher
temperature turn the knob clockwise, for a
lower temperature counter-clockwise.
The temperature can be set from 70°C up
to 110°C (during sauna operation). 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
temperature 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 from 90 to 95°C in the bench
area can be preselected.
3.2 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. Use
the three buttons below the digital display
Åto set the vaporizer performance level.

These amounts are reachable, although
they are higher than the amounts actually
needed.
Therefore, reduce the amounts after the
preheat cycle; to do so, set a lower value
using the program key Ã. Please note that
the cabin temperature is highest under the
cabin ceiling, although the relative humidity
is proportionally lower at this point. The
relative humidity rises in proportion to the
falling temperatures from the cabin ceiling
to the cabin floor.
The following diagram (Illust. 16) shows
you the temperature values proportional to
the relative humidity for the most common
types of sauna bathing and comfort zones.
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
strongly on the configuration of the sauna
cabin, the type of sauna oven used and the
power of the vaporizer. Therefore, it is
important that you find your personal climate
zone. Always choose the temperature first
(from 30 to 60°C) and then the steam level.
Tip: For the preheating time, select a higher
steam level (=duration of operation), so that
the volume of water contained in the
vaporizer (up to 8 liters depending on the
model) will be heated more rapidly. When
the oven and vaporizer are optimally
adjusted to the sauna cabin, the values for
humidity given in Illust.15 can be reached at
100% duration of operation.
Operation using the vaporizer function is
activatedviathe middle CLIMA key Ä. The
value set for the last operating cycle
appears in the display (in case of first-time
operation, this is 0). With the two
programming keys placed to the left and
right of the CLIMA key, (up and down),
Illust.13, you can program in amounts
between 0 and 99%.
Illust. 13
Press CLIMA key once
The vaporizer is always activated when an
amount between 1 and 99% 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 65°C. Please note also
that the vaporizer starts up only after the
temperature falls to this level.
The value shown in the display reflects the
time-proportional vaporizer adjustment.
Therefore, the display cannot be adjusted
for or show the relative humidity, but rather
the frequency of vaporizer activation. The
table (Illust.14) is meant to clarify this.

3.2.1 Turning off steam operation-
supplemental heating function
The steam operation program is stopped
by pressing the CLIMA key. At the end of
operation, a drying program is begun. The
sauna is automatically heated to about
90°C for 20 minutes. The operating
sequence of the supplemental drying pro-
gram is exhibited by the blinking 7-
segmented display.
The supplemental heating temperature has
been preset by the manufacturer to 90°C
and is not adjustable. If the supplemental
heating program must be interrupted or if it
is necessary to turn the system off
completely, set the function dial to 0.
3.2.2 Low water shutoff
Vaporizer tanks are equipped with an
overheat safety shutoff as a state-of-the-
art standard. When this safety is activates,
for example, when the water level in the
vaporizer tank is too low (water deficit) and
is not filled within two minutes, the control
unit turns off for safety reasons and two
dashes(--) appear on the display.
english
Please note: Some vaporizers are
equipped with a buzzer, providing an
acoustical signal as an additional warning
when the thermostat in the vaporizer
registers a water deficit.
4. Troubleshooting

4. Check supply air and exhaust air
Poti Dial for temperature control must stop
at right and left and must not be able to be

4.1 Checking the overheat safety
shutoff
The control unit is equipped with a safety
shutoff in the form of a temperature
governor. This temperature governor is
located in the sensor housing over the
sauna oven and is connected to the
control unit with the white sensor lines. If
the sauna oven is not turned off due to a
flaw in the electronics, the overheat
shutoff registers temperatures starting at
140°C and breaks the circuit to the safety
shutoff of the control unit and
consequently to the sauna oven.

11
After such a shutdown, the overheat safety
shut off must be replaced and the sauna
unit or the control unit monitored by an ex-
pert.
Note to the electrical technician: You can
easily check the function of the overheat
safety shutoff by shorting the two contacts
for the shut off line on the control unit or
checking to see whether 0 V is indicated
on the proper plug. At a high-ohm
temperature check, this is defective and
you will measure the control voltage.
4.3 Checkingthetemperature sensor
The control unit determines the temperature
witha KTYtemperature sensor. Thesehave
a positive temperature coefficient; that is,
the resistance of these components rises
as a function of the temperature.
An important value is the resistance at nor-
mal room temperature. At 20°C, this is
about 1,9 k!"
To determine the temperature on the
temperature sensor, you can measure the
low voltage on the sensor plug with a
voltmeter (measuring range 20 V DC) and
calculate the temperature value using the
diagrams (Illust. 17).
Illust. 17
5. Heating time extension
The control unit is adjusted for a maximum
heating time of 6 hours at delivery. This
heating time limit can be extended to 12
hours.
To do so, it is necessary to remove a
resistor underneath the dial on the control
board.
To get the correct position of the resistor,
please look at Illust. 18. To accomplish
this, it is absolutely necessary to switch off
the fuses or the main switch.
Caution: As a matter of principle, this
work may only be undertaken by a
professional!
Remove this resistor for a
heating time of 12 h
