When cables are routed from the unit, a
protection sleeve for the conduits (PG
insertions) can be inserted at the knockout
hole.
When you do not use a wire conduit,
protect the wires with vinyl tubes to
prevent the edge of the knockout hole from
cutting the wires.

Making field settings
7.2.1
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.
