The Zone Control family of products includes switching relays, zone valve controls, priority zoning circulators, fan controls, and add-on controls. The products come with external diagnostics to show full functionality and make troubleshooting quick and easy. They are fully compatible with conventional and programmable thermostats. Switching relays can be expanded up to 20 zones with priority, and are available in one, two, three, four, and six zones. The company's zone controls allow for easy multizone wiring. For advanced features such as post-purge and priority protection, PowerPort plug-in cards are offered. The expandable (-EXP) control can interface with boiler reset controls and injection mixing. Zone valve controls work with two-, three-, or four-wire valves. Priority zoning circulators are available in a range of sizes to match specific system requirements.
