Control Panel, BMPLUS 3000, 3-Zone EWC-BMPLUS-3000

The Zone Control Panel (EWC-BMPLUS-3000) is a 24 VAC low-voltage system controller designed to manage up to three comfort zones, with optional expansion capability to five or seven zones using XM-2 modules. It supports single-stage and two-stage conventional systems, as well as heat pump and dual-fuel configurations, handling up to three heating stages and two cooling stages. The panel features a built-in supply-air sensor, automatic mode changeover, and a 50% rule that prevents second-stage activation unless more than half of the zones are calling for conditioning. With an input range of 18–30 VAC (50/60 Hz), maximum current draw of 15 VA, and built-in 4-amp overcurrent protection, it is rated for operation between –20 °F and 160 °F. Technicians appreciate its reliability, expandable architecture, and simplified setup—making it a powerful, flexible solution for managing zoned comfort systems efficiently.
