VAV Controllers

Intelligent VAV controllers that can be used for Pressure Dependent and Pressure Independent VAV Applications. In the pressure independent applications the controllers monitor the air flow over the VAV boxes and control it to the required flow setpoint. The flow setpoint is automatically adjusted by the room temperature control loop providing accurate and stable control of the room temperature. The controllers can also combine CO2 and VOC air quality measurement and control.
