aSENSE VAV Duct Display

aSENSE VAV Duct is a standalone controller with built-in sensors that measure CO and temperature for installa­tion in the ventilation duct. This product has an industrial housing and is also prepared for Modbus.

Defining attributes

  • Cost-optimized for direct linear control of dampers and speed regulated fans
  • Contributes to lower energy costs when applied in Demand Controlled Ventilation
  • Internal automatic self-diagnostics
  • Available with different measurement ranges and several housing options
  • Serial communication port for connection to a PC or a GSM module and local network

A common application for aSENSE VAV Duct is controlling ventilation in rooms occupied by people. The sensor is flexible and designed to suit many different ventilation strategies. It is a key component for energy-effective, healthy climate control of rooms where occupancy varies, like schools, nurseries, cinemas, sports centres and libraries etc. The control of the ventilation is often based on temperature and carbon dioxide measurements. That can be combined with control of humidity to secure an optimal environment for the objects. To avoid condensation problems, it is often necessary to measure humidity in air conditioning and other cooling applications.
