FUNCTIONS
AIRFLOW CONTROL
Three adjustable speeds
Reduced speed, normal speed, extra speed
Three adjustable working modes
CAV constant air volume
Fan speed is adjusted in dependency of the pressure lost of the filter in order to maintain the adjusted airflow
Each fan is connected to a pressure transmitter which allows to enter different setpoints to each fans

AIRSENS CO2
Indoor air-quality control device with a built-in CO2 sensor. Especially designed to create DCV systems directly used with single-phase or ECOWATT fans, depending on the relay or analogue control output selected.
Main features:
4 working modes:

•  Relay output and Modbus (reading).
•  0-10V output and Modbus (reading).
• 2-10V output and Modbus (reading)
•  Full Modbus control.

Adjustable set point. Air-quality level indicator (3-LED diffuser). Adjustable brightness 3-LED diffuser.
