with the possibility to choose one of the three submenus "Info", "Control" or
"Service".
In the middle of the window the control type (Room or Supply air) is displayed
and the corresponding actual values (Room or Supply air) below.
Below the actual values a symbol indicates, whether the unit runs in day or night
operation. Day operation corresponds to operation at the first setpoint temperature.
