Heat source demand
As soon as a demand is issued to the heating circuit pump, a demand will
also be issued to the heat source. A minimum runtime can be set.
Weather-compensated set boiler temperature
If there is BUS communication between the Wolf heating control unit and
the Wolf air handling control unit, the set boiler water temperature can be
speciedbytheairhandlingcontrolunitaccordingtodemand.Thisallows
theowtemperaturetobematchedtotherequiredheatingoutputoftheair
