5. COMMISSIONING
5.1 Guided commissioning procedure
Hecu can be confi gured the fi rst time from the pGDe or pLDpro user
terminal. If the controller has not yet been confi gured, the user terminal
shows the fi rst screen in a guided confi guration procedure, called the
“wizard”. Otherwise, the same menu can be accessed from branch: L
Setup >> b.wizard.
The main parameters needed for general confi guration are shown one at
a time. The wizard screens are all numbered in the top right corner; the
following explanations refer to this number. To go from one screen to the
next press È, while to return to previous screen press Ç.
Screen Lb01: indicates the type of system, either medium or low
temperature.
Screen Lb02: change unit of measure from SI (°C, barg) to Imperial (°F,
psig).
Screen Lb03: indicates the type and number of compressors.
Screen Lb04: used to choose the type of refrigerant (R410A, R404A,
R448A, R449A) and the type of inverter (no PEC, PEC).
Screen Lb05: Indicates the model of BLDC compressor and the serial
address of the power+ inverter (always=1). This is used to understand
whether the inverter is on and connected via serial with Hecu
Screen Lb06: indicates whether the connected model of inverter is
compatible and if so automatically downloads some typical compressor
parameters to the inverter. The parameters can also be written manually
by selecting “Yes” for Write default.
Screen Lb07: specifi es compressor control based on pressure, and the
corresponding refrigerant.
Screen Lb08: indicates the compressor control set point and diff erential
set as default by CAREL based on the type of application and the
refrigerant. The type of control is always proportional and integral,
and when exiting the wizard, control will be fi xed set point only until
confi guring communication with the cabinets, when the fl oating suction
pressure set point can be enabled.
Screen Lb11: used to enable a fi xed-speed backup compressor.
Screen Lb91: Indicates the number of fans. A maximum of 2 fans can be
selected.
Screen Lb92: indicates the type of fans, either ON-OFF, PWM or 0-10V
modulating.
Screen Lb95: specifi es condenser control based on pressure.
Screen Lb96 Lb97: indicate the type of fan control and the working set
point and diff erential.
Screen Lb3a: indicates the end of the wizard procedure. Press ENTER
to terminate the procedure, and start system confi guration using the
chosen settings.
Caution: wait a few seconds for the automatic default download
procedure to start and conclude.
