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 by simple 3-key operation.
The HP7 offers precise water temperature control, accurate defrost management, anti short-
cycle protection, circulator pump management, compressor contactor control… 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, chlorine vapors,
and vibration.
The HP7 is an excellent alternative to electromechanical controls.
