NOTICE
When routing earth wires, secure clearance of 25 mm or
more away from compressor lead wires. Failure to observe
this instruction properly may adversely affect correct
operation of other units connected to the same earth.
The power supply wiring can be routed from the front and left side.
Fix it to the lower mounting hole.

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.
