PKZ1900081 6‑zone hydronic control relay panel with pump (...)

The Taco TACZVC406‑EXP‑4 is a hydronic zone valve control panel engineered to manage up to six zone valves in residential or light commercial heating and cooling systems. Equipped with built-in pump priority circuitry, it ensures that a primary zone (such as a boiler or heat pump) receives power priority when all zones are calling, protecting associated pump or equipment operation. The panel includes LED indicators for valve status, easy-to-connect terminal strips, and has provision for adding two additional zones using expansion modules—ideal for future system growth. Designed for compatibility with Taco ½″–2″ power open/close valves, it simplifies wiring and control for efficient zoned temperature management.
