Hässleholm, just like many other municipalities, needs to regulate parameters such as the pressure with several pumps.
The following specifications apply:
- The pressure must be kept stable.
- When another pump needs to be started, this must be done optimally.
- When demand drops, pump must be stopped in order to optimise the energy consumption.
- The pumps are run alternately.
_ The system goes automatically to standby mode in response to zero demand.
- The pumps can be stopped manually for servicing, and the system adapts itself automatically.
