Unit general status
When the user interface is installed inside a
room, the indoor air temperature and the air
setpoint are normally shown on the display.
For the interfaces installed on the machine,
the display normally shows the water tem-
perature and the water set point.
In addition to these temperatures, the con-
trol unit also offers the possibility of con-
trolling other parameters, thus allowing the
device's status to be monitored.
A list of these parameters (shown exclusively
in read-only mode) is provided below
