Hi, my last post on this part "Price differential pressure sensor" (because it is almost off-topic anyway).
Of course, I believe you both that you realized it cheaper.
Regarding my situation and wishes, two companies independently suggested my mentioned price range. When building, I always say: take the higher value.
- Of course, a corresponding 5-core cable already runs to the utility room. Since the electrical installation took place immediately after the shell of the house was erected, at a time when no one knew exactly where which ventilation system would go, it ends at a place quite well guessed by me, but not perfect. Further laying work. Although not expensive.
- I don’t just drill a hole in my house wall. The rain, driving rain, and wind/pressure tightness must be permanently maintained. The outside appearance should not suffer either.
So I would have had that done, if only for warranty reasons (and also because after all the construction work I really had no desire at all to do it).
- My ventilation system has a fireplace function.
A solution that simply switches off the power of the system at the distribution box would not have been an option for me. Therefore, someone would have had to work inside the system (and would have needed some parts, I didn’t look into that further). I wouldn’t have done that myself either, because of warranty (and as above: no desire).
Now – the fireplace function can also be activated manually and I do that when I light the fireplace.
Thus, *for me* the mentioned price would have resulted.
Exactly as it was cheaper for you.
I’m glad that I was spared that.
