1. Introduction of the Innova Controls
1.1 Precautions
Congratulations on your purchase of Innova Control Unit!
Innova Control Unit is developed to enhance your sauna bathing with a
variety of features. It can adjust temperature, humidity, ventilation and
light option in your sauna. The Innova Control Units are available on a
separate or built-in mounting on the Power Controller.
The following information provides you with instructions on adjusting the
settings of the control unit. Please, read this instruction manual
carefully before using it. Familiarization of key functions will give you a
more enjoyable sauna experience.
Only a qualified electrician is allowed to make electrical connections and
repairs on the unit. Use original parts only.
Disconnect the Power Controller and the Contactor Unit from the electri-
cal circuit before installation, opening the lid of the power controller or
contactor unit and repair.
Check power supply rating before installation.
Check the correct location of the sensor in the installation section of the
manual. It is very important to place the temperature sensor correctly
as it closeness to the air ventilation cools down the sensor and may lead
to overheating.
The control unit can be operated in a room temperature 0-40°C. Do not
install the control unit inside the sauna room!
Do not pour water in the control unit or clean it wet cloth. For cleaning
purposes, use a cleaning cloth that has been only slightly moistened
with a mild soapy solvent (dish detergent).

When the control unit is in the pre-run state,
it will display the remaining time of the
pre-run. The confirmed pre-run settings are
saved for the next session.
When the pre-run function is used for the
first time control unit estimates the time that
the heater needs to reach the set tempera-
ture. For example, if the pre-run time is set
to 2 hours, the heater will be switched on in
1.5 hours.
If the sauna has not reached the set
temperature by the time it is meant to be
ready, in this case 30 minutes, it will remem-
ber this. Next time the pre-run function is
used, the heater will be switched on earlier,
for example 50 minutes before the end of
the pre-run time.
Alternatively, if the heater reaches the set
temperature too quickly, it will adjust itself to
be switched on later. The control unit
teaches itself to switch the heater on at the
ideal time in order to reach the set tempera-
ture when wanted.
The pre-run function has different default
settings, depending on the installation
location. For domestic use, the default time
is 6 hours, including the pre-run time as well
as the session time. See more details in the
installation section of the manual.
Always check that there is no combustible material,
like towels, above the heater, nor inside the safety
distances, before switching the heater on! The
safety distances are stated in the heater manual.

This function is available only if the drain option
is present on the Power Controller.
Please Note:
7English
When the water level is low, a low tone
interval beep and “FILL” will be displayed to
alarm the user. There are two possible ways
to fill water levels, automatically or manually,
depending on the model.
The auto Combi heater has a solenoid valve,
which will automatically react to the low level
of water. The water inlet will open to fill up
the tank and steamer session can be conti-
nued without intervention.
In the manual fill, the alarm beeps and
“FILL” will be displayed as long as the user
fills the tank.
However if the user does not refill the tank
and it becomes empty, a high tone interval
beep and “dry” display will alarm the user.
The steamer will automatically be switched
off now, only the heater will be working.
The automatic refill mode will refill itself now,
if it did not refill its tanks earlier. Always
check that the water supply is open before
using the automatic refill Combi heater!
2.3.2 Water refill
10 minutes after the steamer session, the
heater will automatically dry the sauna
room. The cabin drying is set to 30 minutes
at 70°C; the fan speed is at 100%. The
total drying state will take 40 minutes. The
remaining cabin drying time will be
displayed on the interface board.
If the steamer operation is changed to
heater only, there will be no cabin drying at
the end of the session.
The cabin drying session can be stopped
earlier by pushing the power button.
2.3.3 Cabin drying
This function is activated 1.5 hours after
the steamer session time or straight after
cabin drying.
The drain function can be activated in two
ways:
The automatic drain function can be
enabled or disabled when the control unit is
in “OFF” mode. Long press the mode
button and at the same time turn on
controller by pressing the pre-set button.
There will be feedback on the display. If the
automatic drain is on, “Adr” and “on” will
be constantly displayed in sequence. When
it is off, “Adr” and “off” will be displayed.
Long press the Power button to drain
the tank without delay
Automatic drain after 1.5 hours after
steamer session, i.e. 1.5 hours after the
user has pressed the Power button or
1.5 hours session time has ended.

2.3.4 Automatic drain (not in all models)
The state for “HOT” depends on the second
sensor, the bench sensor. If it is a tempera-
ture sensor only, and the bench tempera-
ture in the sauna room is 56°C or more, the
steamer cannot be activated. With the
temperature sensor, the user can choose
the relative time for the steamer to be on,
within 30-100% of the session time.
However, if the second sensor is combined
temperature humidity sensor, the maximum
bench temperature for the steamer to work
is 80°C, as long as the relative humidity in
the sauna room is not too high. With the
combined sensor, the user can choose the
relative humidity inside the sauna room.
The steamer can be switched off manually
by pressing the mode button for less than 3
seconds.
Note:
Do not connect 2 bench sensors at
the same time (TS2 or T/H Sensor).

One or two sensors can be connected to
the Power Controller. The first sensor
measures the temperature, it is the sensor
with temperature fuse and thermistor.
The second sensor, the optional bench
sensor, is a temperature sensor or
combined temperature humidity sensor.
The combined sensor is capable of
measuring the humidity as well as the
temperature.
With two sensors it is possible to receive
more accurate measurements from the
sauna room.
If the heater is mounted on the wall or
floor standing less than 200mm from the
wall, the first temperature sensor needs to
be mounted on the wall above the heater.
Place the sensor 150mm from the ceiling
(Fig. 8 & 9).
4.4 Sensors
However, if the heater is more than 200mm
from the wall, place the sensor to the ceiling,
over the heater, as shown in the figure 10 &
11.
The optional second sensor should be
mounted on the wall, opposite to the heater,
minimum 30cm from the ceiling and minimum
130cm from the floor (Fig 8 & 10). It is
designed to measure the bench temperature,
so ideally place it close to the shoulder height
of the sauna goers.
Do not place the sensors near the air ventila-
tion. The closeness of the air vent cools down
the sensor. Thus, an incorrect temperature is
displayed and the heater may overheat
(Fig.11).
4.2 Power Controller
If the heater used is more than 15kW, an
additional contactor is needed. The contac-
tor unit is linked to the main Power Control-
ler with a RJ12 cable (Fig.7).
4.3 Contactor Unit

Controller on a dry location, outside the
sauna room.
Install the Power Controller on the wall in
vertical direction only and at least 30cm
from the ceiling (refer to Fig.5).
The heater is connected to the electrical
network semi-stationarily with a H07RN-F
rubber cable or its equivalent. The use of
PVC-insulated cable as a connecting cable
is prohibited due to thermal embrittlement.
The maximum distance of the junction box
from the floor is 400 mm, measured from

The maximum sauna session time depends
on the purpose of the sauna. For domestic
use, the total on-time of the sauna is limited
to 6 hours. *)It includes pre-run time and the
session time. The factory setting for the
control unit is 6 hours.
For condominiums, hotels and similar
locations, the operating period of the sauna
heater is limited to 12 hours, including the
pre-run time and the session time.
For public sauna, the operating period of the
sauna heater can be either 18 or 24 hours.
Please note, if the public sauna is set to 24
hours, it will be on constantly. It needs to be
continuously attended.
The maximum heater on-time is set by the
jumpers on SCB1 in the power controller,
see the picture 3. Jumpers 3, 4 and 5 are
meant only for public sauna rooms. Only a
qualified electrical can change the settings.
The standards and regulations of the coun-
try where the control unit is installed must
be followed, when setting the jumpers.
When no jumpers are placed, the default
time is 6 hours. See the Table 1.
Please Note:
If no door sensor is installed, "Door
switch" terminals in the Power Controller
must be connected with each other by a
jumper wire. See fig. 2. Note: connection
is not present in the drawing.

sensor disables all pre-run operations if the
door is opened while the pre-run count-
down is active.
The door sensor also ensures that the door
is not open for long periods of time when
the heater is on. If the heater is on and the
door is open for more than 15minutes, an
alarm and “DOOR” will be displayed to warn
the user. The heater will be switched off
automatically.
