7.3 DHW heating in instantaneous heating system
The instantaneous DHW heating system can be configured in systems Anl 1.9.0, 11.9.0 and
11.9.1.
Without a flow switch, the controller can only regulate the DHW temperature to 'Day DWH set
point' during the times-of-use of the circulation pump. The flow switch allows the controller to
recognize exactly when DHW is being tapped. By deleting all the time-of-uses for the circulation
pump P2, it is possible to regulate the DHW temperature to 'Day DWH set point' just while the
DHW is being tapping.
When the tapping is finished, the valve closes and the heat exchanger charging pump P1 is
switched off after a delay.
