The White International WHI-SK20PPHS2 controllers are devices used to control electric 240V pumps of 1.5kW or less.

The controller monitors both the pressure and the flow. It controls the operation of the pump automatically. Because of its design, there is no need for a separate pressure (expansion) tank, nor is there any need to adjust start and stop pressures as per traditional pressure switches.

The unit will protect the pump should the water supply fail (due to blockage in the pipe or tank running dry) and will automatically restart normal operation once water is restored.

Features and Benefits

• Starts and stops the pump automatically when the tap is open or closed. This means the pump does not need to be turned off manually.
• Maintains a constant pressure from the pump during operation resulting in a reliable water supply.
• Automatically stops the pump in the situation of no flow (due to inlet pump blockage) and will automatically resume normal operation once the blockage is removed.
• Automatically restarts the pump in the event of power failure. This gives the homeowner peace of mind that the unit will continue to operate even if they are away for a long period of time.
• The controller eliminates pressure fluctuations at flows as low as 1L/min.
• Plug and play leads (IEC type) are installed on the controller so that a licensed electrician is not required to replace the controller.
• The controller incorporates an inbuilt pressure gauge to enable the homeowner to monitor the system pressure without the need of a separate inline pressure gauge. The pressure gauge can also diagnose nuisance upstream water.
• Drinking water AS/NZS4020 approved in Australia and New Zealand.
