Whale Watermaster Pump Controller (with Intelligent Control). A giant leap in innovation for caravanners, the Watermaster Intelligent Pump Controller removes the need for adjustment of the pressure switch and also removes the requirement for a surge damper. The Watermaster Intelligent Pump Controller will also prevent your pump running drying by automatically switching off - prolonging the life of your submersible pump.
The Whale Watermaster Intelligent Control can be simply retro-fitted to any Whale Watermaster pressure switched socket (ES1001 or ES5001). The controller is not compatible with any other makes of socket or in-line pressure switches. It should also only be used with a High-Flow pump (not included).
