The indicator shows the operating condition of the module.
If a fault occurs on the module, the mixing valve in the
connected heating circuit will be set to a position determined
by the module. This means that it is possible to continue
operating the system with a reduced output.
Certain faults are also shown on the display of the user
interface assigned to the heating circuit, and on the display of
the higher-level user interface where applicable.
