The Whale Watermaster IC Intelligent Controller Switch ES8000B provides intelligent 12V water pump control for compatible caravan and motorhome systems, eliminating manual pressure switch adjustments while protecting against dry running, pump pulsation and low-voltage operation.
Designed to improve the performance and reliability of your caravan water system, this advanced Whale controller offers a convenient upgrade for compatible Whale Watermaster pressure-switched installations. By automatically monitoring pump operation, it helps maintain a more consistent water supply without the need for repeated manual pressure switch adjustments.
One of its key advantages is intelligent pump calibration. The controller learns the electrical current characteristics of the connected pump during a simple one-step calibration process, allowing it to manage pump operation electronically. This helps eliminate the need to continually adjust the pressure switch as operating conditions change.
The controller also helps prevent water pump pulsation, a common issue in caravan water systems where the pump rapidly switches on and off. By managing pump operation at higher voltages, the Watermaster IC helps deliver smoother water flow and a more comfortable experience when using taps and showers.
An important safety feature is its automatic dry-run protection. When the external water container becomes empty, the controller detects the condition and switches off the pump. This helps prevent unnecessary operation without water, protecting the submersible pump and potentially extending its working life.
The Whale Watermaster IC also monitors low-voltage operating conditions, preventing the pump from running continuously when battery voltage becomes insufficient. This intelligent protection helps reduce unnecessary battery consumption while supporting reliable water system operation.
Featuring built-in fault diagnostics, the controller makes it easier to identify certain operating problems within the water system. Its service-free design also reduces routine maintenance requirements, making it a practical addition for regular touring.
The ES8000B is designed for straightforward retrofitting to compatible Whale Watermaster external inlet sockets with integrated pressure switches, including the ES1001 and ES5001. It must be used with the appropriate Whale Watermaster High Flow Pump EP1612.
Unlike the complete Watermaster IC pump assembly, this product is the intelligent controller unit only, making it suitable for upgrading an existing compatible installation or replacing a faulty controller.
Upgrade your caravan water system with the Whale Watermaster IC Intelligent Controller Switch, combining automatic pressure management, dry-run protection and intelligent pump monitoring for more reliable everyday water performance.
