Electrical Connection To The Ahu - Komfovent VAV Manuel D'installation

3. ELECTRICAL CONNECTION TO THE AHU

When pressure sensors are mounted, they must be connected to the automation of the AHU. If pressure
maintenance is needed in both airflows, two pressure sensors must be connected. Depending on the type of
automation, electrical connections must be performed strictly according diagrams 3a or 3b.
VAV function can also run with only one pressure sensor. In that case, pressure will be maintained in the
airflow, where pressure sensor is connected and the fan of other airflow will follow in parallel (master-slave
configuration). Pressure sensor is connected only to these automation terminals, which corresponds to the
airflow where sensor is installed.
For sensor connection it is recommended to use 3×0,5mm
