7.1

Overview: Configuration

This chapter describes what you have to do and know to configure
the system after it is installed.
It contains information about:

▪ Making field settings

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
Push buttons By operating the push buttons it is possible to:
▪ Perform special actions (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.

unit" on page 36.

Description
Mode 1 and 2
Mode
Mode 1 Mode 1 can be used to monitor the current
situation of the outdoor unit. Some field setting
(monitoring
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.

To access the field setting components

It is not required to open the complete electronic component box to
access the push buttons on the PCB and read out the 7‑segment
display(s).
To access you can remove the front inspection cover of the front
plate (see figure). Now you can open the inspection cover of the
electrical component box front plate (see figure). You can see the
three push buttons and the 3 7‑segment displays and DIP switches.
