We first tested a Rondostat and then decided to convert all our "main heater". Installation and programming are easy, the supplied adapter, we have not needed. The two required AA batteries are not included. The Rondo State perform their job reliably. The set temperature is maintained very accurately. The bathroom is, for example, the morning warm without the heating was on all night and in the study, the heating is safe from even if you forgot to turn back again. If you decide not to heat up times at other times this is not a problem, we adjusted the heater as you need them and the next switching point that Rondostat jumps back into the "normal operation". Or to set the controller to manual then operate these as normal thermostats, but with degree more accurate indicator. Parental Controls have the Rondo State also, but we do not use. The working window open detection, the radiators are with us but just on the other side of the room so that it takes a little to make up the controller, so we but take it by hand. A small change there because of the direction of rotation. Normal thermostatic valves to turning and counter clockwise on. Here leg Honeywell Rondostat is it the other way. While it is indicative of the direction of a regulator in the red and blue arrow, but at the beginning I always falschrumgedreht.
