iO HVAC Controls ZP4-ESP-KIT 4 -Zone, Two-Position Forced Air Zone Control Panel

The ZP4 with ESP is a 4 zone, two-position forced air zone control panel. The panel can be used with single-stage, multi-stage, heat pump or dual fuel equipment with up to 3 stages of heating and 2 stages of cooling. Slide switch configuration makes setup quick and easy. This zone control system comes with built in ESP static pressure control which eliminates the need for a bypass damper when used with the standard 3-wire MD damper series.
