Making field settings

6.1.1

About making field settings

To configure the heat pump system, 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:
[2‑8]=4.
PC configurator
For VRV IV-S heat pump system 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: "6.1.9 To connect the PC configurator to the outdoor
unit" on page 20.
Mode 1 and 2
Mode
Mode 1 Mode 1 can be used to monitor the current
situation of the outdoor unit. Some field setting

contents can be monitored as well.
settings)
Mode 2 Mode 2 is used to change the field settings of
the system. Consulting the current field setting
(field settings)
value and changing the current field setting
value is possible.
In general, normal operation can be resumed
without special intervention after changing field
settings.
Some field settings are used for special
operation (e.g., 1 time operation, recovery/
vacuuming setting, manual adding refrigerant
setting, etc.). In such a case, it is required to
abort the special operation before normal
operation can restart. It will be indicated in
below explanations.
