DANGER: RISK OF ELECTROCUTION
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
