3.1.3 Functions
Detailed information about the functions of the individual controllers is given in the rele-
vant pieces of documentation.
The district heating controllers make possible remote operation and monitoring of all
key data via the M-bus interface. The operating software "ACS Operation" has the data
grouped in accordance with its use. The grouping corresponds to the makeup of the
popcards.
