Several times I have checked the device, but there really is no point. Although time and program had been set properly even after controlling well taken, the thermostat was also on the program, he did not consider the set temperatures. Since three temperatures are set fixed, ie for night, and Komfort1 Comfort2, this amounted to 18, 19 and 20 °, in the room but temperatures 16-24 ° prevailed, makes this device obviously not what it should.
If it does then it out, it governs itself a wolf, that stimulates much more often at the valve around than its predecessor, as well as very noisy, as others have complained here. Other devices are as much quieter.
Even if it kept the temperature for once as intended, it is so easy too loud and governs much too often. The predecessor HR20 was already mounted in the bedroom, what's thankfully made in 1 minute and this bad design is a complaint back to Amazon.
