A pplications
When provided with a dedicated application program, the controller can be used
to control different kinds of equipment:
•
chillers and heat pumps;
•
roof-top units;
•
air-conditioners;
•
small/medium-sized air handling units (on request);
•
refrigerated showcases (on request and to specifications);
•
cold rooms (on request and to specifications);
•
curing rooms;
•
compressor racks;
•
universal stage controllers.
1.1 Functional layout
The figure below shows the functional layout of an air handling unit. Damper
actuators and valve actuators are field 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 humidifier control
board and the fans exchange data and receive set points 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 data are exchanged via Ethernet port (ref.
D). In the same network it is possible to connect another c.pCO controller as well
as to communicate with remote cloud service tEra or to BACnet™ supervisor. The
system can be connected to other supervision systems (Konnex®, LON®, etc.) after
installing the relative BMS1 expansion card (ref. B).
