Electronic control and regulation accessories. The Wilo-HiControl 1 series is used for borehole pumps to enable automatic operation. Wilo-HiControl 1 protects the pump against operation with a low volume flow. The volume flow sensor and pressure sensor enable Wilo-HiControl 1 to automate the pump between two values: the start-up pressure and the switch-off volume flow. If the pressure in the network is lower than the start-up pressure, Wilo-HiControl 1 starts the pump. The pump continues to operate until the volume flow falls below the value of the switch-off volume flow. The small internal tank prevents water hammer and cycling. Wilo-HiControl 1 can be mounted on surface pumps or connected to submersible pumps for domestic water supply. Special features

Pump control (5) | |||
Electronic control unit with frequency converter for speed control of pumps for non-aggressive clear water containing no suspended matter. The electronic control unit makes it possible, independent of the respective flow rate, to keep the pressure within the system at a constant, previously set target value (Automatic operation) and thus also to minimise the power consumption. The pressure remains constant at the previously set pressure value. The pump can be tested in manual mode at its maximum speed. The Wilo-ElectronicControl starts the pump in automatic mode when the system pressure falls below the set pressure by more than the set pressure difference. Once the system pressure has reached the set pressure, the Wilo-ElectronicControl stops the pump after a time interval that has been previously set. The Wilo ElectronicControl protects the pump against
