Installation- and Operating Instructions
SAUNA exclusiv 9kW
Sauna control 400V
Art.Nr. 3112600003
Function:
The electronic control unit Sauna-exclusiv consists of a power component and of a flat
control panel intended for surface mounting. In the power component there are all
connections for the power supply connections, the sauna heater, the ventilator, the cabin
lighting, the sensor and for the control panel. The power component controls the
temperature in the sauna cabin within the range of 70°C to 110°C. For safety reasons the
maximum temperature in the cabin is limited to 139°C by an additional temperature fuse.
The built-in counter timer enables an automatical switching on of the heating to an
adjustable point of time for a heating period of max. 6 hours. The heater, the cabin lighting
and the ventilator may be switched on- and off on the control panel. The temperature
selection as well as the setting of the counter timer are also operated on the control panel.
Any operational information is displayed on the display of the control panel.
Technical Specification:
Dimensions: Power component: 220x218x108mm³
Control unit: 194x157x23mm³
Operating voltage: 3N AC 400V
Control power draw: ca. 6VA
Breaking capacity: 9kW (AC1)
Control range: 70-110°C
Temperature limit: 139°C
Protection type: IP 44 (splash-proof)
Ambient temperature: 0-40°C
Fitting:
According to their protection type both the control unit and
the operating unit are to be fitted outside the sauna cabin to
be protected against damp. The operating panel must be
fixed near the sauna cabin door.
According to the accompanying drawing the temperature
sensor should be side-mounted to the heater near the cabin
ceiling. The side clearance to the middle of the heater
should be around 500mm. The clearance to the ceiling
should not exceed 200mm. You should avoid placing the
sensor near the exhaust opening or the door as well as near
the cabin corner.

The power supply of the device has to be carried out by an universal-pole main switch
having a contact opening width of at least 3mm. Before opening the casing it is
absolutely necessary to discharge the device from voltage.
Electric connection:
The electric connection as well as all adjusting and service operations may only be
carried out by an approved electrical expert! The enclosed connection plans and the
current safety regulations in force are to be followed.

To ensure a smooth distribution of the load among the three switching contacts in the
control device, the U1, V1 and W1 connector must not be bridged in the control device.
The outer conductors are to lead separately to the heating coils. Please note that with a
monopolar feeding the zero conductor of the heating will carry the treble amount of current
of the outer conductors. This current must not be fed to the circuit board via the
clamps. The zero conductor of the heating has to be externally connected to the zero
conductor of the circuit feeding!
The electronic control is fused on the circuit board by a 0.16A fine fuse. In the control
device the connected consumers are not protected against short-circuit. The short-circuit
protection has to be ensured by suitable constructional fuses (max. 16A).
The power component is connected with the control panel by a four-conductor telephone
line (osf-Art.Nr. 3100000500). The maximum length of the line is 30m.
Lines within the sauna cabin are to be heat resistantly equipped.

Check list for probable malfunctions:
Any system components are factory-checked for their functions. Should any disturbances
occur even though, the following items should be checked, provided the proper installation
in any case, and whereas the connecting lines – soundly operated- need to be fixed
properly in the supply terminals.
1.) Does the line voltage fit tightly between the supply terminals L1, L2, L3 and N ?
2.) Has the temperature sensing system been fitted according to the fitting instructions?
3.) In case of a malfunction of the control panel:
Keep the control at the constructional main switch
without voltage and check the fine-wire fuse for the
control electronic and the control panel. These are
situated inside the power component on the circuit
board.

4.) If the heating does not work:
4.1. In case of overheating the sauna cabin the thermal electric fuse which is
situated in the sensor casing in the cabin, will switch off the heating. After
cooling down it is not automatically switched on and the sensing system has to
be changed.
Checking the temperature fuses:
−Disconnect from the clamps 5 and 6 located at the power component, both
cable conductors of the red line.
−Measure the temperature fuse by using either a resistance meter or a
circuit continuity tester.
A defect temperature fuse does not show any conduction.
4.2. For safety reasons the heating is automatically switched
off in the following cases: the temperature sensor is
defect, there has been an interruption or the sensing line
Sensor defect
18:32

Operating Instructions Sauna exclusiv 9kW Page: 6
shows a short-circuit.
Checking the temperature sensor:
−Disconnect both cable conductors of the
white line from the clamps 7 and 8
located at the the control device.
−Measure the temperature sensor with a
resistance meter.
At room temperature an intact temperature
sensor shows an electric restistance of
approx. 68kOhm (see accompanying
coordinate).
5.) Should the set temperature not be reached with a properly working temperature
control:
5.1. The temperature sensing system has to be installed according to fitting
instructions. Should the sensor have been placed in the warm air flow above
the heater, it needs to be moved sideways as far as the rising warm air cannot
cause an early switching off of the heater.
5.2. Should the sauna heater be switched off with
soundly installed sensing system, this problem is
then to be solved by adjusting the temperature
range. For this a trimming potentiometer has
been placed on the circuit board (see sketch).
