About combining units and options

NOTICE
To be sure your system setup (outdoor unit+indoor unit(s))
will work, you have to consult the latest technical
engineering data for VRV IV-S heat pump.
The VRV IV-S heat pump system can be combined with several
types of indoor units and is intended for R410A use only.
For an overview which units are available you can consult the
product catalogue for VRV IV-S.
An overview is given indicating the allowed combinations of indoor
units and outdoor units. Not all combinations are allowed. They are
subject to rules (combination between outdoor-indoor, combinations
between indoor units, etc.) mentioned in the technical engineering
data.
4.5.2

Possible combinations of indoor units

In general following type of indoor units can be connected to a VRV
IV-S heat pump system. The list is non-exhaustive and is depending
on both outdoor unit model and indoor unit model combinations.
▪ VRV direct expansion (DX) indoor units (air to air applications).
▪ SA/RA (Sky Air/Residential Air) direct expansion (DX) indoor units
(air to air applications). Further referred to as RA DX indoor units.
These indoor units require a BP box.
▪ AHU (air to air applications): EKEXV-kit+EKEQ-box are required,
depending on application.
▪ Aircurtain (air to air applications): CYV/CAV (Biddle) series,
depending on application.
INFORMATION
▪ Combination of VRV DX and RA DX indoor units is not
allowed.
▪ Combination of RA DX and AHU indoor units is not

To instruct specific operation with an external input coming from a
central control the external control adaptor can be used. Instructions
(group or individual) can be instructed for low noise operation and
power consumption limitation operation.
The external control adapter has to be installed in the indoor unit.
PC configurator cable (EKPCCAB)
You can make several commissioning field settings through a
personal computer interface. For this option EKPCCAB is required
which is a dedicated cable to communicate with the outdoor unit.
