Demand controller for pressure and constant flow ventilation• Demand controller for EC-fans or e.g., a frequency inverter.
-Variable air volume (VAV)
-Constant air volume (CAV)• User friendly menu, easy setup
Technical specification• Controlled output signal: 0-10 V (Imax = 0.3mA)
The sensor control module for differential pressure and volume flow measures and indicates the pressure or, optionally, the volume flow in a ventilation system. The calculation of the volume flow is performed by entering the K-factor of the application.
Depending on the desired setpoint value and control range, the sensor control module generates 0-10 V to control the EC fan or e.g., a frequency inverter.
The sensor control module is supplied by the fan or frequency inverter which it controls, e.g., with 10-24 V DC.
