LC-ZEC310-0 Johnson Controls Verasys

The CCS Zone Damper (ZEC300) and Bypass Damper (BYP200) Controllers are components of the Commercial Comfort System (CCS) equipment family. The Zone and Bypass Damper Controllers run a preengineered HVAC zoning application and provide the inputs and outputs required for this application. These controllers ship factory-configured, for field installation, on a CCS zone or bypass damper assembly.
The Zone and Bypass Damper Controllers include advanced operating modes and multiple features that ensure occupant comfort. A carbon dioxide (CO2) demand controlled ventilation (DCV) mode, in the Zone Damper, regulates CO2 levels within a zone by allowing fresh air into the zone during occupied times. Occupancy sensing capability enables the controller to switch from occupied mode to standby mode based upon the presence of local activity. Standby mode maximizes energy savings by using setpoints that are higher and lower than occupied mode setpoints.
