Requirements of the control system
● Service water must be available at all times. An emergency control system must change
over to drinking water supply, for example, if service water runs low.
● The ingress of service water into the drinking water network must be prevented when
switching over to drinking water supply.
● The pump must be disabled if the service water reservoir runs low of water (dry-run
protection).
