Installation and User Manual FONDA DET
3.3. Installation of control unit and sensor
The control unit has been connected electrically by a cable to the sauna heater. The control unit T1 and EC 50
must be installed outside the sauna room. Enclosure protection IP X4
The sensor is mounted to the sauna wall, directly on the centre line of the sauna heater, 40 mm from the
ceiling. See page 7
NOTE!
If the wall on which the sensor is to be installed is made of highly heat insulating material (e.g. concrete, brick
etc.) or if the wall is made of toughened glass, the sensor can be installed directly above the heater (on the
heater's centre line viewed from both the front and from the side). See page 7
Deviations from the fitting dimensions specified can lead to a risk of fire!
The temperature limiter in the sensor interrupts the heater's temperature output if the heater's temperature
increases to such an extent that it represents a danger for the sauna's wooden parts. When the temperature
has fallen, the limiter can be reset by pressing the reset button.
Before resetting you must always investigate why the temperature limiter was triggered!
3.4. Connection of the sauna heater to the mains
The sauna heater must be connected to the mains by a qualified electrician and in compliance with current
regulations. The sauna heater is connected with a semi-permanent connection. Use H07RN-F (60245 IEC 66)
cables or a corresponding type. Other output cables (signal lamp, electric heating toggle) must also adhere to
these recommendations. Do not use PVC insulated cable as a connection cable for the sauna heater.
A multipolar (e.g. 7-pole) cable is allowed, if the voltage is the same. In the absence of a separate control
current fuse, the diameter of all cables must be the same, i.e. in accordance with the front fuse.
The connecting box on the sauna wall should be located within the minimum safety clearance specified for the
sauna heater. The maximum height for the connection box is 500 mm from the floor. See page 9.
If the connection box is located at over 500mm distance from the heater, the maximum height is 1000mm from
the floor.
Sauna heater insulation resistance:
The sauna heater heating elements may absorb moisture from air, e.g. during storage. This may cause leak-
age currents. The moisture will be gone after a few heating sessions. Do not connect the heater power supply
through a ground fault interrupter.
However, adhere to the effective electrical safety regulation when installing the sauna heater.
