The ZP6 with ESP is a 6 zone, two-position forced air zone control panel to expand to as many as 12 zones. The panel can be used with a single-stage, multi-stage heat pump or dual fuel equipment with up to 4 stages of heating and 2 stages of cooling. Slide switch configuration makes setup quick and easy. This zone control system comes with a built-in ESP static pressure control module, which eliminates the need for a bypass damper when used with the standard 3-wire MD damper series. A wide range of control options provides ultimate application flexibility.
