The Zone Damper (ZEC310) and Bypass Damper (BYP200) Controllers are components of the Verasys changeover bypass 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. The controllers are ready to be installed and configured on a zone or bypass damper assembly when they are shipped.
Bypass Damper Controllers control a bypass damper to control duct static pressure. The Zone Damper Controllers include advanced modes of operation 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 adding fresh air into the zone during occupied times. The Controller uses occupancy sensing capability to switch from occupied mode to standby mode based on local activity. To maximize energy savings, standby mode uses setpoints that are higher than the occupied cooling setpoint and lower than occupied heating setpoint.
