Comfort, energy saving

Of these thermostats I am thrilled difficult.
In conjunction with 2 window contacts and above all a far CCU2 are 6 units in use, and there are even added more. For this purpose, 7 actuators joined for the electric shutters.
It's fun to program the whole thing and then sit back and know it is only heated when you need it or want. The heating of the road with the smartphone was ever turned on full blast before we came home, so the children can jump right into the shower.

The installation was uneventful, and the link to the window contacts (thanks CCU) that cause means that the heating is automatically interrupted as long as the window is open ventilation purpose what so often happens in the bathroom and in the bedroom.
We have several radiators (old building, 3 apartments) and so far the thermostats could always be attached. At worst, a special pliers needs to be purchased or borrowed, which is "around", otherwise you will not get the old down.
The only thing that gives me a little comfort, is the consumption of batteries. Whether in 2 years must provide a truck for fresh juice?

A clear recommendation.
