KfW 55 - Ventilation system yes/no? - Experiences

Can anyone definitely say if there is a Helios ventilation system that is eligible for funding in combination with an Alpha Innotec LWDV? Then I could simply ask for this specific system....

Have a look at the Maico funding info (just google Maico BAFA). It says, among other things:
One of the following conditions must be met to apply for the government funding:
Direct connection between the controlled residential ventilation device and the heat pump with a common controller (analog or digital) via cable or wirelessly via WiFi, Bluetooth, radio, etc.

That means it is independent of the ventilation system, as any controlled residential ventilation can be made "smart." Of course, you are on the safe side if you have the planned combination including the control measure confirmed in writing by BAFA.

A silly question about that. What is there to "smartly" control in the controlled residential ventilation in combination with the heat pump?

So which parameter X of the controlled residential ventilation would one like to control when the heat pump is in state Y?

What is there to regulate "smartly"

I can't really think of a truly sensible application case for this. Maybe you want to prevent, from a control perspective, the controlled residential ventilation from going into bypass mode while the heat pump is running. Normally, a temperature sensor with a setpoint handles this in the controlled residential ventilation. Not that this wouldn’t be sufficient. It looks more like smart home and digitalization.

It depends on which task is the priority. These can be, for example, air quality values, efficiency, energy-saving modes, anti-icing protection, etc. etc.

Depending on what is required and to what extent the systems are integrated, possibilities of feasibility arise.

Two systems working side by side like that are not always the best solution.

It really makes no sense to pair these two devices. How high is the subsidy and since when has it existed?

Since 01.01.2020. 35%.
