I definitely don’t think it is connected incorrectly, because I can feel the fresh air; the opening is directly above our bed. But the technician is coming later, and I will ask him about everything again.Since I do not have a controlled residential ventilation system installed, a quick follow-up question. The supply air is in the bedroom and the exhaust air in the bathroom, right? And is it connected correctly? I just want to make sure that the fresher air isn’t arriving in the bathroom, then heated further in the hallway, and then transferred to the bedroom? I think we had a controlled residential ventilation system connected the wrong way a few years ago here.
At the moment the pump is stopped again, I have been out until now. If the pump runs again and I catch it then, I will measure directlyHallway and bedroom each down by 0.4, small bathroom to 2. I'm now on the way to Denmark, will get back in the evening. Please also [temperature supply and return small bathroom]
Attached are the supply and return temperatures.The room temperatures are still good You can still reduce parents to 0.75. Tomorrow during heating measure the return temperature. Then adjust the return for the dressing room accordingly. The two heating circuits should have about the same return temperature. Please measure the supply and return of the small bathroom, then check the current supply and return temperature in the heat pump control and set both here. The return temperature in the living area should also be approximately the same. If you have bought the recommended thermometer, you can place it directly, measure 3 times for self-check. Presumably, the base point with 21 is too low, we'll see. Show the heating engineer the unreadable flow tube, he should actually replace it...
Could it be that the heating was off at the time of reading?
Of interest is the supply return shortly before the end of a heating cycle.
How long does the pump now heat per heating cycle?
