aSENSE VAV Display

_x000D_ aSENSE VAV is a standalone controller with built-in sensors for temperature, humidity, and carbon dioxide. The unit measures both the CO₂ concentration and the temperature in the ambient air and converts the data into analog and digital output signals, which are used to control the air supply on demand. An additional cooling compressor for dehumidification can also be controlled. aSENSE VAV is intended for installation in the climate zone or in a ventilation duct._x000D_ APPLICATIONS_x000D_ A common and extensive application for aSENSE VAV is controlling ventilation where people are present. The Sensor is flexible and designed for many different ventilation strategies. It is an important component for energy-efficient, healthy climate control of spaces with varying occupancy, such as daycare centers, sports centers, etc. In museums and libraries, etc., the ventilation control based on temperature and carbon dioxide measurements can be combined with air management. To prevent condensation problems, it is often necessary to measure humidity in air conditioning and other cooling applications. This Sensor is a basic component that can be used in many different ventilation applications, used in industrial/agricultural process controls. Alternative control outputs
