Very satisfied 378

Purchased to replace older Danfoss RAV guy who heads began to date seriously, the difference is impressive.
Easy to assemble (on body radiators Danfoss, I do not know if this also installs easily on other manufacturers), simple enough to program for as long as one downloads the complete directions because the document is very brief . Controls the room temperature accurately and in time slots that can be changed at will. Little more, the lighting of the LCD screen to properly see what you're doing even in the dark!
Contrary to previous opinion I have absolutely no problems encountered, the window function works very well. Have had no problem buttons, plastic or screen. On batteries I can not comment because recently installed but expected to last 2 seasons according Danfoss.
May be faulty or improperly installed thermostat?
