Multiple outdoor units
To connect the power supply for multiple outdoor units to each other,
ring tongues have to be used. No bare cable can be used.
The ring washer which is standard provided should be removed in
that case.
Attaching both cables to the power supply terminal should be done

6.1 Making field settings
6.1.1 About making field settings
To continue the configuration of the VRV IV heat pump system, it is
required to give some input to the PCB of the unit. This chapter will
describe how manual input is possible by operating the push
buttons/DIP switches on the PCB and reading the feedback from the
7‑segment displays.
Making settings is done via the master outdoor unit.
Next to making field settings it is also possible to confirm the current
operation parameters of the unit.
Push buttons and DIP switches
Item Description
Push buttons By operating the push buttons it is possible to:
▪ Perform special actions (automatic
refrigerant charge, testrun, etc).
▪ Perform field settings (demand operation,
low noise, etc).
DIP switches By operating the DIP switches it is possible to:
▪ DS1 (1): COOL/HEAT selector (refer to the
manual of the cool/heat selector switch).
OFF=not installed=factory setting
▪ DS1 (2~4): NOT USED. DO NOT CHANGE
THE FACTORY SETTING.
▪ DS2 (1~4): NOT USED. DO NOT CHANGE
THE FACTORY SETTING.

PC configurator
For VRV IV 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 28 .
Mode 1 and 2
Mode Description
Mode 1
(monitoring
settings)
Mode 1 can be used to monitor the current
situation of the outdoor unit. Some field setting
contents can be monitored as well.
Mode 2
(field settings)
Mode 2 is used to change the field settings of
the system. Consulting the current field setting
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.
