Berner Adds BACnet, Adaptive Settings Berner AIRController/App for Air Curtains

Berner International has added adaptive settings and true BACnet compatibility to its Berner AIR to better support client sustainability goals. The Berner AIR is a smart controller and app platform that e connects end users to their commercial doorway air curtains via the internet for programming, operating and monitoring.

The app-based adaptive setting feature boosts energy efficiency by automatically calibrating the airstream performance, according to the weather. Berner AIR’s onboard Intelliswitch controller reports local weather conditions (via the Berner AIR’s Internet connection), the doorway temperature (via an onboard sensor) and air curtain model data every 20 minutes to factory servers. Factory-engineered software then uses proprietary algorithms to determine the best volume, velocity and uniformity balance for the given moment and adjusts the fan speed based on the current weather. Pinpointing the most energy-efficient of 10 available air curtain fan speeds helps buildings meet energy conservation, sustainability and carbon footprint goals, while also supporting thermal comfort.

The newly added BACnet communication capability is standard on Berner’s premium Architectural Elite 8 and 10 models, and optional on all other Architectural Series air curtains when ordered with the Berner AIR. BACnet allows programming, operating and monitoring from the Berner smartphone app or the building management system.

The BACnet feature allows control of:

  • Preset programming (Comfort Plus, Auto, and PureAir)
  • Fan speed
  • Time delay; thermostat temperature set point and type
  • Time/day set
  • Lock PASScode
  • Start/stop time
