INFORMATION
It is important that all information in this chapter is read
sequentially by the installer and that the system is
configured as applicable.

6.1
Making field settings
6.1.1
About making field settings
To continue the configuration of the VRV IV heat recovery 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 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
Performing special actions (automatic refrigerant charge, test run,
etc.) and making field settings (demand operation, low noise, etc.)
happens by way of operating the push buttons.

PC configurator
For VRV IV heat recovery 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 26

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.
