The Commercial Comfort System (CCS) Zone/Bypass Damper Assemblies are zone control and pressure control devices that include the damper and control components in a factory assembled configuration. The assembly includes the round or rectangular damper, configured Direct Digital Control (DDC) controller, electric actuator, pressure sensor (in the bypass damper only), National Electrical Manufacturers' Association (NEMA) Type 1 enclosure, and an optional control power transformer.

The controllers are application specific, factory programmed digital controllers that communicate via the BACnet® Master Slave/Token‑Passing (MS/ TP) Protocol. Both the zone and bypass controllers operate as part of a larger zoning system and provide zone and pressure control for the appropriate mechanical equipment.

The zone damper modulates in response to temperature variations relative to a user defined space temperature setpoint. The bypass damper modulates to maintain supply duct static pressure setpoint.
