Thermostats I like good, very easy to set up, a variety of additional functions (holiday program, summer break, ventilation function, temperature adjustment) ... And most importantly, they are really very very quiet.
The case is somewhat small, the screen is flush with the housing, is very easy to read.
Required adapter for Danfoss valves are.
A star deduction there, because the metal coupling nuts just lying there. Who is not versed here knows once not know how he should gotten the already mounted plastic nut. A small manual would be helpful here. With a little courage and a small screwdriver, can you bend back the clip slightly and then remove it with pliers, the plastic nut. Alternatively saw open. The metal nut is then simply pressed firmly and slide into position.
Should now also turn out a good life, that would be the perfect thermostat for me.
Update on 08/03/2014: thermostats operate far more properly. However, a thermostat is creating a kind of "shadow" on the display, that all segments of the LCD digits are a bit "illuminated" so that depending on the viewing angle, the display is not reasonable to read.
