16.1 Making field settings
16.1.1 About making field settings
To continue the configuration of the VRV IV replacement 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 replacement 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" [

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.

16.1.3 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 three 7‑segment displays and DIP
switches.

Operate the switches and push buttons with an insulated stick (such
as a closed ball-point pen) to avoid touching of live parts.
Make sure to re-attach the inspection cover into the electronic
component box cover and to close the front plate's inspection cover
after the job is finished. During operation of the unit the front plate of
the unit should be attached. Settings are still possible to be made
through the inspection opening.
NOTICE
Make sure that all outside panels, except for the service
cover on the electrical component box, are closed while
working.
Close the lid of the electrical component box firmly before
turning on the power.
