6.6.3.2.  VAV Control (variable airflow), with CO

2

 sensor or similar

CAD-COMPACT units are equipped with EC motors. The motors have specific terminals for sending a regulation 

signal to control fan speed (0-10V). The 0V signal corresponds to the fan stop, while the signal of 10V corresponds 

to fan maximum speed.

To perform the speed regulation in VAV with speed control with external sensor of CO2 or similar, it is necessary 

to use the accessory CONTROL CAD-REG and the external sensor (see point 7.5.2.4.). In the CONTROL CAD-REG 

instruction booklet it is contained the necessary  information to carry on the electrical connection of the different 

components.
