Operating modes: To support the full range of available combination options in multivalent heating
systems with buffer support, the control system offers the possibility to set various
operating modes for buffer operation. The different settings cause different
processing sequences of heat requests for heating circuits and hot water. In the
following, the different operating modes are illustrated using exemplary hydraulics
layouts.
Operating mode 1 – Charging control HC and DHW requests
System hydraulics:
Heating-circuit and hot-water control send their demand value to buffer control.
Buffer control requests additional energy from the heat generator via the buffer
loading pump.
See the table below for detailed correlations.
