so ... Today the field service from Wolf was here and took a look at the whole situation:
- In general, from his point of view there is nothing to criticize about the valve positions. They are certainly not installed according to the craftsman instructions, but the airflow is given and the air quality (as I was also able to measure) is good. The keyword was "Dutch positioning"
- The flow quantities are somewhat unbalanced – for that he is creating a new ventilation concept for me (regarding the quantities) and will implement it if necessary, in case I can’t (which I assume)
- Dust deposits next to the disc valves are also seen as normal, since there is a turbulence there which deposits the dust: simply easy to clean
- The pipes are free of dirt and dust after about 30-40cm inside the pipe, should also be easy to clean and is rather due to the system not running continuously
- The siphon of the controlled residential ventilation was clogged because it was installed with a slope towards the device: not dramatic, but not good
- Filters were okay, but not the best: I am now switching to G4/G7 – this means the device has more work, but in the new development area certainly not for nothing
- The power consumption is unfortunately normal like that: the device is protected from frost damage this way; you can only preheat the air e.g. by an air well or geothermal exchanger
Errors we certainly made:
- We generally switched off the system in the summer at hot temperatures and only turned it on for "shock ventilation" for 2-3 hours in the morning and evening -> mortal sin. The system should always run, even if only for moisture protection
- Likewise, it was wrong to switch off the system at sub-zero temperatures to save electricity -> Better to keep it running on "moisture protection"
- Smart Home connection, which was still missing, is now done via an RJ12 interface with switching via a switching actuator. Configuration then via ISM7E interface and Wolf app
Addressing too dry air in winter / too humid/stuffy/warm air in summer, we came to the joint conclusion that it is best to counteract independently of the ventilation system: I am now quite convinced that we will not get by without air conditioning to keep the indoor climate/temperatures in the green zone. I hope for a decent connection Photovoltaic inverter -> KNX -> air conditioning/controlled residential ventilation to control the air quality in the house adapted to the internal/external conditions.
Many thanks already for your suggestions!
