ᐅ Looking for a bathroom exhaust fan with humidity sensor, ducted exhaust only

Hello Everyone,
For the wet rooms (bathroom, guest toilet, and utility room) in the new build of a single-family house, only exhaust ventilation systems are required due to the conditions for "KfW 55EE". I have already had the wall openings for DN 100 installed as well as the power cables for connecting the fan (constant power).
I am now looking for an exhaust fan with the following features:
- pure exhaust air
- DN 100
- humidity sensor
- runs on constant power (no switch connection available)
- backdraft damper
- adjustable settings for run-on time and humidity level at which it turns on or off
I have already searched extensively on Amazon and read reviews and specifications. So far, I have only found one suitable option: the Lospitch bathroom fan.
Maico offers the "maico eca 100 ipro kh," but it says the settings can only be adjusted using a switch.
Do you have any additional recommendations for a bathroom fan that meets my requirements?

...As compensation, window frame vents and these three exhaust devices were required. Nothing more.Exactly that (window frame vents) is the remainder of the ventilation system.

In principle, this should be technically quite simple, and the heat would not be exhausted outside the house. I don’t know if the electricity cost would be higher than the savings.
Maybe that’s the reason why such a device doesn’t exist?

WilderSueden20 Dec 2022 11:56There are plenty of construction dryers with hose connections available, so you can definitely find a basement dryer like that. They also look a bit nicer.
Honestly, it’s relatively pointless. You pass by the bathroom every day and could empty the bucket yourself. Thanks to windows, you can also get rid of moisture without a construction dryer, and if you’re going to invest money, it’s better to invest in a proper ventilator. That also has lower electricity costs than a dryer running continuously at 0.5 kW.

I have an older De’Longhi device at home, though I don’t know the exact model number right now.
I just quickly looked up some other examples and, for instance, check out the De’Longhi DDSX220WF.
There are certainly more models available in different price ranges. However, they tend to be on the more expensive side, not the $100 devices.

WilderSueden20 Dec 2022 21:07Then you use a decentral ventilation unit with heat recovery. A construction dryer requires considerable effort to remove moisture, which consumes energy. For, say, 0.5 kW of the dryer’s power, you can get 1.5–2 kW of heating output from the heat pump. Overall, this is much more energy-efficient.
