The function of the controller do what they should.
Class I find the offset adjustment to each other to vote Heizkörperregler from.
I have my control all coupled together in a room.
This means that all regulators are controlled or regulated together with the window down on radio.
Here also the temperature offset is good, because some radiator heating and other less fully Bummern.
The controller has a boost, so for 5 minutes, the valve is fully open.
Also, a holiday function is included.
I can only recommend this controller.
Take Lieber few euros more into their own hands and be happy to swap as always.
