MultiBox II
Constant pressure regulation & pressure alarm – Art.No: 13-700
Geovent MultiBox II is an advanced ventilation
control, which is primarily used for constant pressure
regulation (PID / differential pressure) of a fan, & it
also has a build in alarm system, telling the operator
in case that it cannot reach the requested set point.
The MultiBox II is easy to install and has a userfriendly menu system, which lowers the installation
costs.
By using the MultiBox II, 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 II 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.
MultiBox II is recommended for:
• Frequency controlled extraction system (0-10V)
• Regulation of EC-motors in ventilation systems
• Regulation of dampers & Membrane dampers
• Supply air in balance with several process points
• Feedback regulation with up to 3 set points
• Slave control of supply air & room extraction
•Several switch options, for info to central systems,
on usage, alarms, filter alarms etc.
• Pressure control in cabinets with supply &
extraction air, why it is suitable as a Feedback
regulator & Slave control for process ventilation.
Features:
MultiBox II has a built-in pressure sensor (1000 &
5000 Pa) and is supplied with 3 outputs & 3 inputs
with sum-box. It can combine several supply and
extraction systems and regulate according of up to 3
set points. Furthermore it has an alarm function,
adjustable lower and upper levels.
User information is showed on a 2x16 dot display,
which gives the user/installer useful information.
All functionalities on the MultiBox II is controlled by a
powerful micro processor with a built-in EE-prom,
which is used for storage of the software and the
data/parameters, which are typed into it. When 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 filter and
fuse. The unit is CE-marked & EMC-tested.
