Flexible, distributed zone control for HVAC and airflow‑based applications
The ZN253 Zone Controller provides reliable, scalable control for zone‑level HVAC applications, combining graphical programming, open BACnet communications, and seamless WebCTRL® integration to support comfort and energy efficiency.
The controller supports up to 10 total points, including 2 binary outputs, 5 universal inputs, and 3 analog outputs, providing flexible control for zone‑level applications.
Supports native BACnet over MS/TP communications, enabling integration into BACnet‑based building automation systems.
Uses a fast, powerful, and fully distributed control architecture, allowing the controller to operate independently of other system devices.
Firmware upgrades can be performed remotely, and startup and commissioning are simplified using WebCTRL® system user interfaces.
