Instructions for Use and Installation Helo Steam
NOTE: Controlling the lights in the steam room with the circuit board is 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 steam generator
circuit board's relay control must be fitted with a separate relay or contactor for controlling the lights.

Selecting the steam generator output for the steam room
You can estimate the power requirement using the formula below.
Volume (m3) x K1 x K2 = Power requirement (kw)
Mechanical ventilation
No ventilation
Acrylic wall
Light wall board + tile
Heavy wall: stone, concrete + tile
Very heavy wall: stone, concrete + tile
In heavy-built steam rooms, we recommended using e.g. an electric heating cable for warming the seats, walls and
floors.
