VAV Controller

In VAV systems (variable air volume), the supply air is directly linked to the conditions in the rooms and zones. The calculated supply air volume increases with higher requirements or decreases with lower requirements. VAV systems are therefore very energy efficient and ideally suited for room climate control. Comparable CAV systems (constant air volume) require up to 60% more air volume, which, in turn, leads to higher energy consumption. The DEOS VAV controllers are available with an integrated actuator and as a wall-mounted unit. Typical VAV applications are found in office buildings, hospitals, hotels, schools, shopping centres and industrial buildings.

Easy integration of VAV controller

With DEOS VAV controllers, we set new standards when it comes to integration capabilities in new or existing projects. The controller’s free inputs and outputs cover the entire scope of VAV applications and allow flexible extensions or modifications to meet your individual requirements.
