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
▪ DIP switches (only change the factory settings if you install a cool/
heat selector switch).
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: "7.2.9 To connect the PC configurator to the outdoor
unit" on page 31.

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.

Push buttons
Use the push buttons to make the field settings. Operate the push
buttons with an insulated stick (such as a closed ball-point pen) to
avoid touching of live parts.
BS1 MODE: For changing the set mode
BS2 SET: For field setting
BS3 RETURN: For field setting
BS4 TEST: For test operation

changed or when an additional indoor unit is installed
7‑LEDs display
The display gives feedback about the field settings, which are
defined as [Mode-Setting]=Value.
