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.
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
solvent (dish detergent).

WARNING
Do not embed the control unit into the wall,
because it may lead to overheating of the unit
and cause damage!

Power Controller
The Power controller or theseparate control
panel must not be located inside the sauna
room or in places where temperature
can exceed 40°C. It is protected against
water splashes, however it should not get
in contact with water. Mount the Power
Controller in a dry location, outside the
sauna room.
Install the Power Controller on the wall in
vertical direction only, at least 30cm from
the ceiling (refer to Fig.2).
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 500 mm, measured from
the upper corner of the box.

Saunova 2.0 user interface can be installed either
inside or outside the sauna room. Only one user
interface can be used to control the heater.
NOTE!
If the Saunova 2.0 user interface
is installed inside the sauna
room, none of its components
should not be installed higher
than 800mm from the oor.

Contactor Unit
If the heater used is more than 9 kW,
an additional contactor is needed. The
contactor unit is linked to the main Power
Controller with a RJ12 cable (Fig.4).
Follow the instructions that are supplied
together with the contactor unit.
Installation of separate control panel with
power controller and contactor unit
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. 5
& 6).
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 7 & 8.
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. 5
& 7 ). 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.8).

Maximum Session Time
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 switches is set to
24 hours, it will be ON constantly. It needs to
be continuously monitored.
The maximum heater on-time is set by
the switches on DIP switch in the power
controller, Figure 11 (See also DIP switch
session time settings in page 12). Only a
qualified electrician can change the settings.
The standards and regulations of the country
where the control unit is installed must be
followed when setting the DIP switch. Default
time is 6 hours. See the Figure 10.
*) IEC 60335-2-53

Door Sensor/Switch
In other than household use, it is
recommended to install door sensor. The
door sensor disables all pre-run operations
if the door is opened while the pre-run
countdown 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 “oPEn” will be displayed to warn
the user. The heater will be switched off
automatically.
Fan
The fan function can only be activated if the
fan feature is present on the control unit.
Fan can be switched On/Off. The maximum
power is 100 W with 230 VAC.
Remote On
Used for automated households. The remote
signal is a potential free contact. The sauna
heater switches on when contact is closed
and remains on until contact is opened.
When the sauna heater is remotely controlled,
settings use from previous session are
applied. Other buttons are locked. Only the
light, Fan and Steamer buttons can be set.

ENGLISH 11
The Power Controller Main Switch
The power controller switch can be found on the top
end of the unit. Using this switch, you can isolate the
electronics from the mains power supply.
