1. INTRODUCTION OF THE SAUNOVA 2.0 CONTROL
Congratulations on your purchase of Saunova 2.0 Control Unit!
Saunova 2.0 Control Unit is developed to enhance your sauna bathing with a variety of
different features. It can adjust temperature, humidity, ventilation and light in your sauna.
The Saunova 2.0 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.
1.1 Precautions
1. Only a qualified electrician is allowed to make electrical connections and repairs
on the unit. Use original parts only.
2. Disconnect the Power Controller and the Contactor Unit from the electrical circuit
before installation, opening the lid of the power controller or contactor unit and
repair.
3. Check power supply rating before installation.
4. 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.
5. The power controller can be operated in a room temperature 0-40°C. Do not
install it inside the sauna room!
6. 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

steamer will not be activated.

ENGLISH 7
The state for “HOT” depends on the second
sensor, the bench sensor. If it is a temperature
sensor only, and the bench temperature 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.
2.3.2 Water refill
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 continued
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!
2.3.3 Cabin drying
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 total drying state will take 40 minutes. The
remaining cabin drying time will be displayed
on the interface screen.
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.

3.5 Sensors
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. 6
& 7).
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 8 & 9.
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 6
& 8 ). 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
ventilation. The closeness of the air vent
cools down the sensor. Thus, an incorrect
temperature is displayed and the heater may
overheat (Fig.9).

Other possible problems are:
• The control unit is working fine, but
the heater does not turn on. Check the
electricity supply to the heater. Check that
the wires for the sensors are placed into
the correct terminals in the control unit.
• The control unit cannot display the relative
humidity* (only when the combined
sensor is installed). The combined sensor

even though there is plenty of water
in the tank. Make sure that terminals
“empty” and “tank level” are correctly
connected to the right terminals in the
Power Controller.
• The steamer is switched on and “dry”
is displayed immediately. Make sure that
the “WB” terminal from the heater is
connected with the “tank level” in the
