ᐅ Which pressure switch should be used to shut off the mechanical ventilation system with heat recovery?

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?

Thank you, so I can basically install the pressure switch in a different room, which is already good.

Does your pressure switch have a thermostat to detect whether the stove is on? Our chimney sweep mentioned something like that...
What kind of cable did you run to the controlled ventilation system for the purpose of switching it off? Which pressure switch do you use at your place?

I would then install the switch in the airlock and power it with 230 V, then run two hoses into the room near the stove and two to the outside to prepare everything. That’s my idea.

Hello,

we will also be using a tiled stove and a mechanical ventilation system with heat recovery. The tender process for the mechanical ventilation system is still ongoing.

Is a pressure monitor always mandatory?

As a rule, yes, but the final decision rests with the local chimney sweep, with whom you should clarify everything well in advance anyway.

Unless you buy a room-air-independent wood stove and have only a recirculating range hood in the kitchen, not an exhaust hood.

That is not correct – room air-independent does not automatically mean DiBT-certified. The exhaust hood has nothing to do with that, and ultimately, certification is not a guarantee that no pressure monitor is required. If the local chimney sweep says the monitor is necessary, you have to install it.
