8. COMMISSIONING
Commissioning refers to installation of the electrical panel in the field and
setting the air handling unit application software parameters, as well as all the
operations needed to complete the setup of the devices. The Commissioning
procedure is activated on the screen Ge03, after having fitted the BMS
RS485 card on the controller and established the connection to a personal
computer running the pCO Manager program (see the appendix).
8.1 Loading the configuration
If necessary, load the configuration saved following the software
configuration procedure, on screen Gfd01. Once the parameters have been
loaded, the following operations are possible:
1.
verify correspondence of the I/Os to the AHU design;
2. set the PID parameters for temperature and humidity control, air quality
and advanced control functions (cascade, enable direct [DEC] and
indirect evaporative cooling [IEC], supply limits, compensation, etc..). See
the “Functions” chapter;
3. set the auxiliary control loops, if featured;
4.
set the baud rate and serial address for Fieldbus and BMS serial
communication;
5. calibrate the probes;
6.
manually calibrate the fans, coil actuators, humidifier, and activate
purging.
Note: see the screens in menus Ga, Gb, Gc, Gfc, Ge, Gg and the “Functions”
chapter.
8.2 Commissioning
Warning : before performing any operation on the pCO board,
disconnect power to the device by moving the main switch on the electrical
panel to OFF. To configure the parameters using PCO Manager:
Step BMS1 BMS2
A Manually set the protocol to
Winload in screen Ha24: Serial
BMS2-->Winload;
B Disconnect any BMS cards other than
RS485 (e.g. LON);
C Connect the RS485BMS card;
D Activate the Commissioning service on screen Ge03

4.
Reconnect the BMS card and restore the connection;
5. Check that the serial protocol is the same as at the start on Ha24:
-->BMS and Ge01: protocol BMS1: CAREL, Modbus, Lon and Ge02: Protocol
BMS2: CAREL, Modbus, Lon.
Note: the commissioning service automatically sets the BMS protocol to
“Winload”. Once the procedure has ended, the protocol automatically returns
to “BMS”, allowing reconnection to the supervisor.
8.3 Probe calibration
In menus Gfb01 to Gfb08, calibrate the probes if necessary and check the
correct reading against a sample probe.
See the parameters table.
8.4 Setting the control parameters
To set the control parameters see the “Software configuration” and “Functions”
chapters. The parameters can be modified from the terminal or a personal
computer using the pCO Manager program. See the appendix.
8.5 Setting the hour counters
On screens Gfa01 to Gfa06 (see the parameters table) a maximum number of
operating hours before maintenance is required can be set for each device.
On exceeding the maintenance hours, a “warning” is signalled on the display
and recorded in the alarm log, without affecting control. Access screens
Gfa01 to Gfa06 again to reset the warning. The purpose is to allow service
personnel to be notified to ensure preventive maintenance.
8.6 Enthalpy management
Enter the atmospheric pressure for parameter Gfc16 to allow the controller to
correctly calculate the values on the psychrometric chart.

8.7 I/O test
Screens He01 to He50 can be used to test the actuators during installation,
see menu Gg01. Modulating fan actuators can be adjusted from 0 to 100% to
achieve design air flow-rates. For the digital outputs, 0% corresponds to OFF
and 100% to ON.
