Among the features in detail:
- The red LED in the center of the unit warns against excessive blinking LF- the area is fixed with each> 55/60/65%
- Min / max. Values can be a button to the side aufrufen- the device will also be deleted on another button "RESET"
- Dew point is also displayed here, which is quite convenient. If the temperature falls below the walls, condensation would accumulate there and the associated dangers you can certainly count on even a few fingers ... is therefore a very useful and thoughtful information!
- Device can be placed stably be hung on tables or on the wall
To make it short: It is really worth so far, to have invested 20. In the normal case you need it during the winter months less when the house everything is ok. You know at some point that the greater the temperature differences are (outside to inside), it's easier, a tolerable rh value to get in the house by briefly airing and also sufficiently heated rooms.
Have there always are at different places in the house and said as with the title of Rezi, it adapts very quickly.
For me, the acquisition was (it had bought in early October) at the time a lot of sense, as I have repeatedly aired early in the morning and evening rush when the device has flashed red ... honestly you have here but say that the way or frequently occurred this summer and also without the device probably would not have been different .... But nevertheless it helps one through the penetrant flashing LED very good.
What would be best for the future here: sensor measuring the outside temperature, so you can uncover even more efficient. As written above, should between foreign and internal temp. some degrees of difference prevail, otherwise found no exchange of air ..
Conclusion: For those who want to get to keep the values in mind when it comes rh, this unit offers good, but here there's also cheaper alternatives that it can just as well. For all those who want to know it then in more detail with dew point and alarm, the TFA is actually a must.
