If a cooker hood is connected towards the ventilation unit it is important that there is signal from
cooker hood into KV connection plug on the ventilation unit.
This signal can be taken from the cooker hood directly or via a pressure switch in the piping between
cooker hood an ventilation unit.
If a two‐step kitchen ventilator is used then it is important that in the first step, where only the
damper opens, there also is signal from ventilator into KV connection plug on the ventilation unit.
This signal can be taken from the cooker hood directly, if possible, or via a pressure switch in the
exhaust piping from the ventilator.
Kitchen ventilator with integrated fan is not allowed to connect directly to the «Cooker hood» inlet
on the ventilation unit. For this you need to make its own exhaust piping through wall. Anyway you
need to make a signal from kitchen ventilator into KV connection plug on the ventilation unit. This
signal can be taken from the kitchen ventilator directly, if possible, or via a pressure switch in the
exhaust piping from the ventilator.
Inn all cases it is important to see that there are signal in display when activating any steps
on cooker hood / ventilator.
Do this signal show in display on all steps when activating cooker hood / ventilator.
