The AirNexus 8-Zone Damper Controller enables independent heating and cooling zone control for ducted HVAC systems. Mounts on FCU or timber truss, connects to AirNexus VRV32 via bus cable, and drives 24VAC damper motors via RJ12 connectors. Programmable scheduling, remote management via smartphone app or web interface, and energy-efficient airflow algorithms.
Ducted systems often serve multiple rooms from a single unit, and without proper zoning, some areas end up too hot while others are too cold. The Zoning Expansion solves this by giving you independent control over each zone.
Connected through the Nexus controller, every zone appears in the Nexus iQ dashboard where you can set individual schedules, monitor temperatures, and adjust settings remotely. Bypass damper support ensures system protection when only a few zones are calling for air.
8 zone capacity — Control up to 8 individual zones independently
Motorised damper control — Precise airflow management for each zone
Air pulse balancing — Automatic airflow distribution optimisation
Bypass damper support — System protection when zones are partially closed
Remote zone adjustment — Control every zone from the Nexus iQ app
Cloud connected — All zone data available through Nexus iQ
Individual zone scheduling — Set unique schedules for each zone
