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 heat pump.
The VRV IV 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.
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, single outdoor
unit use, multiple outdoor unit use, 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 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).
▪ AHU (air to air applications): EKEXV-kit+EKEQ-box are required,
depending on application.
▪ Aircurtain (air to air applications): CYQ/CAV (Biddle) series,
depending on application.
