The new Vitodens 200 boilers have a new screen. Instead of the line drawing of a roof, there's a partial circle (see below). The temperature under the dome used to be the desired indoor temperature and did not change unless you make a change. The instruction manual says this temperature is the "Set Zone Circuit Temperature". Is this the target water temperature based on the heating curve?
