7. SOFTWARE

CONFIGURATION

Important

: some of the following operations are often carried out

during installation, as the devices are connected in the field and configured.
The software configuration procedure includes these steps:

Select devices (screens Ha01, Ha02);

Configure devices (screens Ha03, …, Ha30);

Assign inputs/ outputs (menu Hb);

Set device control parameters (menu Hc);

7.1 Select devices (Ha)

Once the application program has been installed and the electrical
connections have been completed (see the “Hardware installation” chapter),
the operations required for commissioning the controller depend on the
type of air handling unit, and involve these steps:

Check correspondence between the design AHU -

it’s recommended to

refer to a complete hard copy drawing

- and the AHU managed by the pCO

board with the default parameters. See the “Hardware installation” chapter;

Configurazione Ha01

Dispositivi principali
Ventil.: Mandata-Ripresa

Batterie:

PRE+POSTRISC.

Umidificatore: ABILITATO

Recuperatore: ABILITATO

Fig. 7.b

Note:

selecting the devices on screens Ha01 and Ha02 defines the AHU

and determines which of the following screens or configuration menus for
the inputs and outputs (Hb) are displayed.

If the design AHU is similar to the default AHU, try adding or removing
devices or probes until achieving a complete match;

If the design AHU is very different from the unit managed by the default
parameters, delete all the configured analogue and digital inputs and
outputs. To do this access menu H. Manufacturer

b.I/O configuration

Hb99. Positions deletes to delete the default configuration and then

enter the new configuration;

Access menu H. Manufacturer

a.Configuration to select:

•

Ha01: the main devices on the AHU (number of fans, number of
heating coils, enable humidifier, enable heat recovery unit;

•

Ha02: type of dampers, enable freecooling/freeheating (by
temperature/ enthalpy), air quality control…

Again in menu H. Manufacturer

a.Configuration: configure the type of

devices: modulating valve, floating valve, heaters, no. of pumps for each
coil, type of air quality control and other functions such as purging, type
of frost protection, etc.

See the table of parameters for the list of devices on the “Ha” screens that are
displayed according to the selections made on Ha01 and Ha02.

Example:

the default configuration of the pCO Large includes a heat recovery

unit with bypass damper. If the AHU is designed for an application in which
neither freecooling nor the possibility of frost forming on the heat recovery
unit are envisaged, this device may not exists and therefore can be excluded,
thus freeing an output. Simply access the “Configuration” menu (screen Ha14)
and disable the bypass damper.

7.2 Conﬁgure devices (Ha)

From screen Ha03 on the selected devices, type of control and corresponding
probes are configured. These settings must be coherent both with the
electrical connections made and the software loaded on the pCO board
during installation.

Ha03):

type of fans: with inverter or on/off control, different types, see par. 9.20;

Ha03a): on-off dampers on the supply, return and corresponding limit switch;
Ha04):

type of fan alarms: overload and/or of flow;

Ha05):

Ha06):

type of cooling device: floating valve , modulating valve, floating valve , direct
expansion steps;

Ha07):

type of heating/cooling coil;

Ha08):

type of reheating device: floating valve , modulating valve, heaters;

Ha08):

type of reheating device: floating valve , modulating valve, heaters;

Ha08):

reheating for compensation, supplement, supp compensation;

Ha09):  enable pumps for cooling, pre/reheating coils;
Ha13):  type of humidifier: isothermal or adiabatic, ON/OFF or modulating;
Ha13a):  enable direct evaporative cooling - DEC;
Ha14): type of heat recovery unit: cross-flow, run-around coil or modulating wheel;
Ha14):  bypass damper available;
Ha14a):  enable indirect evaporative cooling - IEC;
Ha15):  air quality control type: P+I or proportional only;

Ha16):  frost protection type: from probe, thermostat, probe+thermostat;
Ha17):  enable unit ON/OFF from digital input or BMS;
Ha18):  enable change set point from comfort to economy from digital input;
Ha19):  enable offset on setpoint from analogue input;
Ha19):  activate auxiliary control loop;
Ha24):  select protocol on Fieldbus serial and BMS serial;
Ha25):  communication speed, parity and timeout for Modbus master protocol;
Ha26):  number of pCOe expansion cards and number of serial probes connected;
Ha29):  configure VFD inverter parameters;
Ha30):  enable probes and digital inputs from supervisor.

7.3 Assign inputs/outputs (Hb)

In the menu H. Manufacturer

b.I/O configuration:

select the type and position of the analogue and digital inputs and the
analogue and digital outputs. For active probes also set the minimum
limit attributed to the minimum input value and the maximum limit
attributed to the maximum input value;

Check the configuration in menu D. Inputs/outputs and the input
readings;

Test the outputs (He01…) to verify correct wiring and operation of the
devices.

Note:

•

the controller automatically identifies which terminals are free and
automatically proposes the first available positions, according to the type
of input (e.g. NTC, PT1000, 0 to 1 V, 0 to 10 V, 4 to 20 mA) based on the
hardware features of the pCO board used;

•

some screens are only shown if the corresponding device has been
enabled and configured.
