3.5 Combining units and options
3.5.1 About combining units and options
NOTE
Refer to the technical engineering data for latest options
and allowable combinations.
The VRV W T-Series water-cooled 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 W T-Series water-cooled system.
An overview is given indicating the allowed combinations of indoor
units and outside units. Not all combinations are allowed. They are
subject to rules (combination between outside-indoor, single module
use, multiple module use, combinations between indoor units, etc.)
mentioned in the technical engineering data.

Possible standard combinations of units
RWEQ192~432 consists of 2 or 3 RWEQ96~144 units.
RWEQ192 = RWEQ96 + 96
RWEQ216 = RWEQ120 + 96
RWEQ240 = RWEQ120 + 120
RWEQ264 = RWEQ120 + 144
RWEQ288 = RWEQ144 + 144
RWEQ312 = RWEQ120 + 96 + 96
RWEQ336 = RWEQ120 + 120 + 96
RWEQ360 = RWEQ120 + 120 + 120
RWEQ384 = RWEQ144 + 120 + 120
RWEQ408 = RWEQ144 + 144 + 120
RWEQ432 = RWEQ144 + 144 + 144
