The Zone Damper (ZEC310) and Bypass Damper (BYP200) Controllers are components of the Verasys zoning system. The Zone and Bypass Damper Controllers run a pre-engineered HVAC zoning application, and provide the inputs and outputs required for this application. These controllers ship factory-configured for field installation on a zone or bypass damper assembly.
The Zone and Bypass Damper Controllers include advanced operating modes and multiple features that ensure occupant comfort. The zone damper uses a carbon dioxide (CO2) demand controlled ventilation (DCV) mode to regulate CO2 levels within a zone. This occurs when fresh air enters the zone during occupied times. The controller can switch from occupied mode to standby mode based on the presence of local activity, due to the Occupancy sensing capability. Standby mode maximizes energy savings by using setpoints that are higher than the occupied cooling setpoint and lower than occupied heating setpoints.
