Function block "Heating circuit" can be used as a "virtual heating circuit". It calculates a
weather-compensated flow temperature setpoint, but does not deliver any output
signals (hence, pump or mixing valve for the heating circuit is not a mandatory require-
ment!). The weather-compensated flow temperature setpoint is delivered to the main
flow and acts as weather-compensated heat demand.
The setting to be selected is "Heating circuit active"; the heating circuit entries are made
on the operator unit as usual. No output terminals are configured.
When a heating circuit pump and/or heating circuit mixing valve is/are configured, the
heating circuit is automatically activated; a "real" heating circuit is created. In that case,
setting "Heating circuit active/inactive" is of no importance.
This setting defines whether the heating circuit is "connected" directly to the main
header or downstream from the primary controller.
