Without flow rate sensor or flow switch, the control of the required DHW temperature at the
flow sensor VF is only active during times-of-use of the circulation pump ZP. The flow rate
sensor or flow switch allows the controller to recognize when DHW tapping starts and stops.
Control of the required DHW temperature can made to be active only during DHW tapping
by deleting all times-of-use of the circulation pump.
The control of the required DHW temperature at the flow sensor VF is only active during
times-of-use of the circulation pump ZP.
