INTRODUCTION OF THE INNOVA CONTROL
Congratulations on your purchase of Innova Control Unit!
Innova Control Unit is developed to enhance your sauna bathing with a variety
of different 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.
Precautions
-
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 electrical 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 power controller can be operated in a room temperature 0-40°C. Do not install it 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).
Power Controller
The Power controller or the separate 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, and 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.
WARNING
Do not embed the control unit into the wall, because it may lead to
overheating of the unit and cause damage!

Contactor Unit
If the heater used is more than 15 kW, an additional contactor is needed. The contactor unit is linked to the main Power Controller with a RJ12 cable (Fig.4).

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.
Follow the instructions that are supplied together with the contactor unit.
Installation of power controller with builtin control panel with contactor unit
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)
Sensor location with heaters mounted on the wall
NOTE
Do not place the sensors too near to air ventilation (not under 1000mm) or not
under 500mm from air ventilation, which is directed away from sensors

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 jumper is set to 24 hours, and it will be on constantly. It needs to be continuously monitored.
Fig. 10
| Sauna Type | Domestic sauna | Hotels, Condominiums | Public sauna |
|---|---|---|---|
| Jumper | 1 | 2 | 3 |
| Max. time | 4h | 6h | 12h |
| Max. pre-run time | 2h – steam 3h – steam | 4h – steam 5h – steam | 99h |
The maximum heater on-time is set by the jumpers on SCB1 in the power controller, Figure 11. Jumpers 3, 4 and 5 are meant only for public sauna rooms. 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 jumpers. When no jumpers are placed, the default time is 6 hours. See the Figure 10.
Fig. 11
Door Sensor
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 “DOOR” will be displayed to warn the user. The heater will be switched off automatically.
NOTE
If no door sensor is installed, “Door switch” terminals in the Power
Controller must be connected with each other by a jumper wire from terminal D
to terminal D. (Figure 4)
Fan
The fan function can only be activated if the fan feature is present on the control unit. Ensure that the fan motor to be controlled is either shaded pole or permanent split capacitor motor. The maximum power is 100 W with 230 VAC.
Dimmer
It is possible to use any suitable lamp of your choice in the sauna room. However, if the dimmer feature is present on the control unit and wished to be used, only incandescent lamp is suitable.
The Control Unit Main Switch
The control unit switch can be found on the top end of the unit. Using this switch, you can isolate the electronics from the mains power supply.
