2.10. Connection of the sauna heater to the mains
Power cable is connected to the port underneath the triangular panel on the back of the Pikkutonttu heater. The OLET 31
sensor and the control panel cable are connected to the M20 circuit board on the bottom of the heater through the strain
relief bushing.
Remove the nut and the rubber grommet from the strain relief bushing. Make a vertical split in the spot where the lead-in
rubber grommet aligns with the hole. Insert the RJ10 connectors and cables of the control panel and the OLET 31 sensor
through the strain relief bushing. Tighten the strain relief bushing nipple.
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 Location the connection box
If the connection box is located at over 500mm distance from the heater, the maximum height is 1000mm from the floor.
Table 2 Connection cable and fuses
NOTE:
Controlling the lights in the sauna with the circuit board is only possible with resistive loads (incandescent light
bulbs). The circuit board relay cannot withstand capacitive loads (switched-mode power supply units). If the lighting
fixtures in the sauna have transformers, for example LED or halogen lamps, the stove circuit board's relay control must be
fitted with a separate relay or contactor for controlling the lights.
Sauna heater insulation resistance:
The sauna heater heating elements may absorb moisture from air, e.g. during storage. This may cause leakage 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.
2.11. Electric heating toggle
Electric heating toggle applies to homes with an electric heating system.
Sauna heater has connections (marked N-55) for controlling the electric heating toggle. Connectors N-55 and the heating
elements are simultaneously live (230V). The sauna heater thermostat also controls the heating toggle. In other words,
home heating turns on once the sauna thermostat cuts power off the sauna heater.
