GENERAL DESCRIPTION of HP7 CONTROLLER
The HP7 is a powerful microprocessor control designed for use in swimming pool & spa heat
pumps. The control features 3-digit temperature and set point display, with programming changes
easily performed via simple 3-button (key) operation.
The HP7 offers precise water temperature control, accurate defrost management, anti short-cycle
protection, circulator pump management, compressor contactor control, refrigerant circuit
pressure monitoring… all with solid-state reliability. The HP7 monitors water and refrigerant
temperatures using precise thermistor sensors. The control also features full diagnostics messages,
simplifying both installation and service.
Additionally, the HP7 offers maximum corrosion and vibration protection: All printed circuit
board interconnections are soldered, and the main Power Board and Display Board are specially
coated for added protection against humidity, air pollutants, and chlorine vapors.
The HP7 is an excellent alternative to electromechanical controls.
