16.4.11 External demand processing
The controller can process binary or analog requests for an externally required signal by a
more complex secondary system. A binary request can only be processed when the input
SF2/RF2isnotassignedtoasensor.
Risk of damage of the heating circuit through overheating.
Overheating may occur in the heating circuits of the primary controller without control valve.
Excessive charging temperatures in DHW circuits without control valve controlled by the pri-
mary controller are excluded when the default settings of the controller are used: while stor-
agetankchargingisactive,noowtemperaturehigherthanthechargingtemperatureis
used by the primary controller. If the Priority for external demand function is activated, the
external demand is also processed during storage tank charging. The heating circuits can be
conguredinsuchawaythattheyonlyprocessexternaldemand.Thepossiblesettingsfor
eachheatingcircuitdonotapplywiththiscongurationasonlytheexternaldemandispro-
cessed with associated UP as feeder pump.
