Making field settings

6.1.1

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: 

"6.1.9  To  connect  the  PC  configurator  to  the  outdoor

unit" on page 20

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.

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

BS5

RESET: For resetting the address when the wiring is
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.

To access mode 1 or 2

After  the  units  are  turned  ON,  the  display  goes  to  its  default
situation. From there, you can access mode 1 and mode 2.

Initialisation: default situation

NOTICE

Be  sure  to  turn  on  the  power  6  hours  before  operation  in
order  to  have  power  running  to  the  crankcase  heater  and
to protect the compressor.

Turn  on  the  power  supply  of  the  outdoor  unit  and  all  indoor  units.
When  the  communication  between  indoor  units  and  outdoor  unit  is
established and normal, the display indication state will be as below
(default situation when shipped from factory).
