The Digi-Zone Panel, Model MDP3, controls up to three zones and is expandable up to 103 zones with additional MDZA two-zone adder panels. The MDP3’s LCD digital display provides easy system configuration and settings. The digital display replaces the DIP switches and dials settings for temperature and timing, allowing more precise control. The MDP3 can control virtually any single-stage, multi-stage, heat pump and dual-fuel system. Used with ZONEFIRST’s Plug-In Damper Motors, each zone can control up to 10 dampers, and all can be easily checked with the damper test button for each zone.
