Can someone tell me what electrical requirements I need to consider for a pressure switch to shut off the mechanical ventilation with heat recovery?
I tried to find information online but didn’t really succeed.
Does the pressure switch need to be installed near the chimney?
Does a hose need to be routed outside to measure the outside air pressure?
Does a cable need to be connected to the mechanical ventilation system to shut it off when the pressure switch is activated?
220 V (220 V) power supply near the pressure switch.
These are the points I would implement now. Can someone tell me if this is correct?

But I wouldn’t overestimate that either.

The expert who conducted the test for us was really impressed by the measured results.
Our construction manager, who was also present, then said that Weberhaus’s stated goal is to undercut the allowable limits by at least 30 to 50%.

Can you tell me what kind of airlock that is supposed to be?

DragonyxXL30 Aug 2016 16:02Despite Bosy, I’m not really making progress on this topic. In my opinion, the best solution would be to install a differential pressure switch that measures the pressure in the flue pipe and the room, and shuts off if necessary. Does this work that way? Are electricians familiar with something like this? My building savings contract doesn’t specify any requirements for the pressure switch, and the chimney installer isn’t an expert on it either. The electrician will be the one installing it, right?
