The ZP2-HC with ESP forced air zoning systems to represent the most contractor-friendly solution today. The ZP2-HC model is designed to fit up to two-zone applications for single-stage heat/cool systems in residential and light commercial applications. This zone control system has built-in ESP static pressure control, which eliminates the need for a bypass damper when used with the standard 3-wire MD damper series.
The system works like any standard zone control system, with one exception. As zone dampers open and close, the built-in ESP static pressure control continuously monitors the system static pressure and, if required, sends a signal to zone dampers in the closed position to open to a point where the proper static pressure level is maintained. The small amount of air allowed to bleed into non-calling zones eliminates air noise and assures proper airflow through the HVAC system preventing coil freeze-up.
