Arens Automatic Ventilation Controller

The Automatic Ventilation Controller coordinates the ventilation of multiple rooms by simultaneously controlling up to 8 additional Zone Controllers. A fully automated natural ventilation and night purge system (if required) can be provided using these controllers, whilst still offering the option of manual operation by the occupants through a Zone Controller.

Windows are opened and closed depending upon control calendar, time of day, rain, wind speed, and internal and external temperature.

The complete range of Arens Electric Chain Winders and Linear Actuators are compatible with the Arens Automatic Ventilation Controller.

  • A fully adaptable automated system
  • Power to operate the panel is either through a 1.5 A plug pack or connection to power output of Arens Relay Module.
  • Easily configurable to individual site requirements by onsite personnel
  • Provides automatic window control systems based on various environmental readings

  • Offers additional functions such as ‘night purge’, and close after hours, when rain is detected or when wind speed threshold is exceeded
