Description
A2G-100 is a multi-function PID controller specially developed for air conditioning systems and ventilation industry to control airflow and differential pressure.
PID controller enables continuous pressure or airflow control electronic commutation (EC) fans, multi-air volume systems (VAV systems) or exhaust fans. Airflow control is achieved by entering the manufacturer's fan constant KFAN in the start menu or using the A2G-FM measurement probe.
0...10 V or 4...20 mA output signal is directly connected to the EC ventilation or frequency converter (FI) as a control signal. The two-line LCD display of the A2G-100 displays both the output signal and the measured value. The user can set the electronic analog output signal of 0...10 V or 4...20 mA through the jumper of the meter. At the same time, the controller supports automatic zero adjustment.
