1.3 Functional layout

The  gure below shows the functional layout of an air handling unit. Damper actuators and valve actuators are  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 humidi 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 pGDx touchscreen terminal, intuitive and simple to use,

can be used while the unit is normally working to set switch-on and switch-o 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 (KNX®, LON®, BACnet™, etc.) after installing the relative BMS1 expansion card (ref. B).
