The Automated Logic ZN220 is a fully programmable, native BACnet Advanced Application Controller (AAC) designed to control individual zones within a building. It is suitable for applications including fan coil units, lighting, and exhaust fan control.
The ZN220 communicates over an EIA-485 network using BACnet MS/TP and integrates with the WebCTRL building automation system. EIKON graphical programming software allows custom control sequences, while a library of standard control programs supports common zoning applications.
The controller supports up to four points, consisting of two universal inputs and two digital outputs. It also supports Automated Logic communicating sensors and OptiPoint touchscreen interfaces for setpoint adjustment, occupancy overrides, equipment management, and troubleshooting.
