This item is a HeatPumPro Panel (4 Zones) manufactured by Arzel Zoning.
HeatPumPro is a full-featured zoning control with built-in staging and software-based programming. The technology is the easiest and most cost-effective way of getting the maximum efficiency out of conventional, dual fuel, all-electric, or heat pump systems.
