1.2 Functional layout

The fi gure below shows the functional layout of an air handling
unit. Damper actuators and valve actuators are fi eld devices that
communicate through Fieldbus 1 (ref. C). Fieldbus 2 (ref. E) is the medium
through which the serial probes communicate the values measured,
and through which the humidifi er control board and the fans exchange
data and receive setpoints from the controller. The built-in terminal and
the remote terminal, which communicate via pLAN (ref. A), are used for
installing the application program and for commissioning the system.
The PGD touchscreen terminal, intuitive and simple to use, can be used
while the unit is normally working to set switch-on and switch-off times,
to enter the main parameters, to perform other advanced functions of
the application program and to view any alarms triggered. In this case the
data is communicated through the BMS2 serial port (ref. D). The system
can be connected to a supervision system (Konnex®, LON®, BACnet™, etc.)
after installing the relative BMS1 expansion card (ref. B).
