Multibox III

The MultiBox III is an advanced ventilation control, which is primarily used for constant pressure regulation (PID / differential pressure) of a fan, and it also has a build in alarm system, telling the operator in case that it cannot reach the requested set point.

The MultiBox III is easy to install and has a user-friendly menu system, which lowers the installation costs.

By using the MultiBox III, will result in the fan constantly adjusting the speed according to the number of extraction points in use. By adjusting the power according to the necessary air flow, will result in lower running cost on the fan, and less of the heated (or cooled) indoor air is extracted.

The MultiBox III can further more give control signals to the central control unit / general AHU, and thereby lower the extraction air flow on the AHU (10-0V), as a slave of the airflow on the process ventilation system.
