iO HVAC Controls ZP3-HCMS-ESP-KIT Three Zone 2H/2C Panel with ESP Kit

ZP3-HCMS-ESP-KIT Includes Only:

• Panel
• Static pressure sensor
• Duct temperature sensor
• 40VA transformer

Features:

• The ZP3-HCMS represents the most contractor-friendly solution today for eliminating bypass.
• The ZP3-HCMS model is designed to fit up to three-zone applications for single-stage and multi-stage heat/cool systems in residential and light commercial applications.
• 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 series dampers.

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 that are in the closed position to open to a point where the proper static pressure level is maintained. The small amount of air that is allowed to bleed into non-calling zones eliminates air noise and assures proper airflow through the HVAC system preventing coil freeze-up.
