ᐅ Controlled residential ventilation / DIBt-certified stove / pressure monitor

Hello everyone,
we are planning to build a prefabricated house meeting the KfW 70 standard.
The house will be heated primarily with a gas/solar (water) system, partly with underfloor heating and partly with conventional radiators.
In addition, a controlled residential ventilation system with heat recovery will be integrated.
We also want to install a stove, since the heat from a stove has a different character.
I am familiar with the technical requirements from my chimney sweep.
This means the stove must be room-air independent and ideally certified by DIBt.
However, as is often the case, the stove we have chosen is room-air independent but does not have DIBt certification.
According to my information, a pressure monitor must then be installed, which shuts off the controlled ventilation system if the negative pressure becomes too high.
My question now is: what does such a pressure monitor look like and how is it installed?
Where does it measure? I assume in the room where the stove is located, but where else?
Does it measure outside? If so, how can I route the sensor outside?
Retrofitting a penetration to the outside later would be problematic due to airtightness concerns.
Can someone bring me up to date on this?
By the way: the range hood will be recirculating and can be disregarded.
Thank you very much!

The plan is basically to mainly operate the stove and hardly ever use the regular radiators. The underfloor heating is only in the bathrooms and living area for aesthetic reasons.
The solar system is only for hot water in the summer, so the heating can be safely turned off for about 3 months.
That explains the whole approach.
I’m grateful for any tips or suggestions, but can anyone still comment on the actual questions?
Thanks!

No!.. Then I would be interested to know which services according to §§ 53 to 56 HOAI were included in the architect’s contract, especially which service phases (LPH) were applied. PhoenixDH schrieb:
...But why is it a money pit? This comment mainly refers to the use of solar thermal systems. Best regards

please don’t be upset, but could you maybe explain the abbreviations to me?
I would appreciate it because, as I said, we are still in the planning stage, so I’m not very familiar with every area.
And I would also like to learn something.
As mentioned, it is a prefabricated house; controlled residential ventilation is included as a standard feature, along with gas heating.
We decided to add solar water heating as well. Also, the combination of underfloor heating and conventional heating.
Thank you.

Since this is not the topic here... and because users from other fields who want to learn about house construction are asking questions, please avoid using internal abbreviations or vague references (e.g., "money pit") that may confuse or irritate the person asking and other readers.

...Also the combination of underfloor heating and standard heating. This is also not ideal, as at least a second mixing circuit with accessories is required. It is better to choose either underfloor heating or radiators.Regards

to come back to this topic again.
We have now found a stove with DIBt approval.
The next requirement for not needing an additional pressure monitor is that our mechanical ventilation system switches off at a differential pressure of 8 Pa (0.03 inches water column).
Otherwise, the additional device will be necessary.
Does anyone know models of mechanical ventilation systems that have this safety feature built in?
Thanks to all.
