ᐅ Flue Control / Pressure Switch for Shutoff of Mechanical Ventilation with Heat Recovery

Hello everyone!
For the approval of the wood stove when a controlled residential ventilation system is present, a suitable regulation or shutdown of the ventilation system is necessary to prevent smoke gases from being drawn into the living space. Can anyone advise me on exactly what is required? Any recommendations? Certifications?
Situation:
- Controlled residential ventilation system by Viessmann
- Wood stove (not open combustion) with its own (room-air independent) fresh air supply from a duct in the chimney
During the electrical planning, the electrician was unsure about the requirements and recommended a stove control system from Brunner including installation for €1250. However, I believe there is a misunderstanding. My concern is not to electronically control the wood stove (automatic damper) but simply to implement a shutdown of the controlled residential ventilation (switched outlet), that is, temperature- or pressure-controlled during the operation of the stove while the stove door is briefly opened for refueling and potential negative pressure occurs.
A preliminary meeting with the responsible chimney sweep will take place soon, but I would like to be informed beforehand. The electrician honestly admitted that he is not very familiar with this and would install something else that the chimney sweep might accept. Even if he cannot get it from wholesale, we are welcome to order it, for example, online.

depends on the chimney specialist. ours requires a pressure monitor (Leda) OR a written confirmation from the gas and water supplier that the ventilation remains below 5 Pascal. which the supplier refuses to provide.
despite the inspected mechanical ventilation stove.Same here, we couldn't avoid getting a pressure monitor...
Hello,
Our contact told us that there is no room for discretion in this matter. It is even regulated by law that with an RLU stove holding a DIBt certificate, no further requirements should be demanded. However, he also mentioned that some colleagues might not be very strict about continuing education...
Best regards,
Andreas

But he also mentioned that there are colleagues who may not take their continuing education very seriously...

AndreasEveryone tells their own story again. Our chimney sweep trains others and seems quite knowledgeable, so I highly doubt that is true. But in the end, everyone is king in their own domain. It’s the same with “I won’t go on your roof, but I will on your neighbor’s.” It’s pretty crazy...
