– Suitable for up to 3 pumps
– The goal is to maintain pressure at the outlet
– Controller turn on the pumps directly without speed regulation of the motors
– If one pump can not compensate for the consumption additional pumps are turned on
– The controller has a hysteresis that prevents too many turn-ons and turn-offs
– When there is no consumption the pumps are on stand-by
– Dry-running protection with pressure switch
– Alternate operation of the pumps
– OPTION: Timed test turn-on of the pumps
