About making field settings

INFORMATION
The LEDs and buttons are located in the outdoor module
(not in the hydro module).
To configure the condensing unit, you must give input to the outdoor
unit's main PCB (A1P). This involves the following field setting
components:
▪ Push buttons to give input to the PCB
▪ A display to read feedback from the PCB
Field settings are defined by their mode, setting and value. Example:
[2‑1]=2.
PC configurator
It is alternatively possible to make several commissioning field
settings through a personal computer interface (for this, option
EKPCCAB is required). The installer can prepare the configuration
(off-site) on PC and afterwards upload the configuration to the
system.
See also: "7.2.9 To connect the PC configurator to the outdoor
unit" on page 31.
