Catalog excerpts

Geovent MultiBox IV is an advanced ventilation controller, which is primarily used for constant pressure regulation (PID / differential pressure) of a fan, and it also has a built-in alarm system, detecting the pressure and giving an alarm if the pressure falls below the set point. The MultiBox IV is easy to install and has a user-friendly menu, which lowers the installation costs. By using the MultiBox IV, t he fan constantly adjust the speed according to the number of extraction points in use. It adjusts the speed according to the necessary air flow, whichresults in a lower energy consumption of the fan, and less heated (or cooled) indoor air being extrac ted. Further the MultiBox IV can give control signals to the central control unit / general AHU, and thereby lower the air flow on the AHU (0-10V), as a slave of the airflow on the process ventilation system. MultiBox IV is recommended for: • Frequency controlled ventilation systems (0-10V) • Control of EC-motors in ventilation systems • Control of dampers and Membrane dampers • Several switch options, for information to central systems, about usage, alarms, filter alarms etc. MultiBox IV has a built-in pressure sensor (0 - 4000 Pa) and it is supplied with 3 outputs and 3 inputs. It can combine several supply air and extraction systems and regulate according to up to 3 set points. Furthermore, it has an acustic alarm. User information is showed on a touch screen, which gives the user/installer i nformation about the status of the system. All functionalities on the MultiBox IV is controlled by a powerful micro processor with a built-in EE-prom. As the processor and EE-prom are built-in, the risk of loss of data is lowered. All vital components are well shielded against external electrical eruption/noise with both filters and fuses. The unit is CE-marked and EMC-tested. Protection class IP54. Ordering table
