Automated Logic ZN141A BACnet VAV Advanced Application Controller

Automated Logic ZN141A BACnet Advanced Application Controller is a fully programmable, native BACnet AAC that delivers zone-level temperature and air quality control for pressure-independent VAV installations. It serves as the zone-control brain within the WebCTRL building automation system, integrating with Automated Logic communicating sensors in a range of zone-sensing configurations and supporting adjustable setpoints and occupancy overrides to tune comfort and energy use. The ZN141A conforms to the BACnet AAC device profile (B-AAC), ensuring interoperability with BACnet devices and third-party controllers. Programmability is enabled through the WebCTRL/EIKON environment, enabling custom logic for VAV sequences and zone control. As a dedicated zone controller in a BACnet-based building automation stack, it coordinates with VAV dampers and related equipment to maintain precise zone conditions across a facility. Custom logic and sensor integration are designed to scale across multiple zones, providing a consistent control framework within Automated Logic’s WebCTRL ecosystem. BTL listings confirm BACnet conformance for ZN141A as a BACnet Advanced Application Controller. This controller is designed to support pressure-independent VAV strategies, helping maintain comfort while optimizing energy use.
