NES FS Series Garage Ventilation Controller


The recently introduced NES FS controller is designed to serve as a “stand-alone” demand-control ventilation (DCV) system for small- to medium-sized commercial garages, but it can be readily scaled to comport with BACnet® and Modbus® communication protocols and deliver a high degree of functionality and value-added features.

The NES FS-20’s built-in VPN allows for secure remote connectivity, and an optional, onboard display facilitates trouble-free commissioning, system adjustments and troubleshooting.  It can be configured to control up to 25 devices, including gas sensors, e.g., CO & NO2, variable frequency drives (VDS) and Input/output (IO) modules.  It can control a single zone or multiple zones.
