The equipment is better than it is given in the description here currently. It seemed good also symbols with a window giving a ventilation recommendation "window" / "window". And that works really well. I put an example a device in a basement. Outside on the basement bay is the outdoor sensor (managed by a truncated PFT soda bottle behind a bush), inside the basement, the device is mounted. Since I already repeatedly go to the basement area daily, the recommendation contemporary pressing the inlet flap in the basement is a handle. The recommendations are absolutely useful, purely out of my head one has the even with knowledge of the physical relationships as soon not in feeling. I have a short time greatly improved the climate in the basement. My dehumidifiers are deposited significantly less water. I immediately bought a second device. All sensors show when they are adjacent, within the tolerances very precisely identical results. => Absolute buy recommendation.
