Please note that your gas boiler or open fireplace will produce exhaust gases through
convection of the heated exhaust air from your living spaces to the outside.
Your exhaust fume extraction works by forced convection and therefore causes
a negative pressure in the living space, which sucks in the exhaust gases and/or the
exhaust gases of their house co-inh
abitants from the chimney brings back.
Functional description:
The control of your OPERA cooker hood is equipped with a window contact circuit. If
the contact loop of the controller is interrupted, the power supply to the fan motor is
interrupted. The OPERA cooker hood lighting continues to function.
The window contact is mandatory in Germany.
Only window contact switches approved by DIBt (Deutsches Institut für
Bautechnik) may be connected potential-free to the contact loop.
The contact must be closed when the window is open!
( pressure switch not actuated = closed ) ( reed switch open in magnetic field )
For detailed wiring options, please refer to the window contact brochure request.
