you have to consult the latest technical engineering data for VRV
RXYQ-A series.
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.
1.2.1. Indoor unit combinations
In general following type of indoor units can be connected to a VRV
RXYQ-A series. The list is non-exhaustive and depends on both out-
door unit model and indoor unit model combinations.
• VRV indoor units.
• Mini-split indoor units.
• AHU (air to air applications): AHU Integration kit is required. See
latest Engineering Data Book for more details .

In order to control the cooling or heating operation from a central
location, the following option can be connected:
- Cool/Heat selector: KRC19-26A
-
With optional fixing box for the switch: KJB111A
- Centralized control devices (e.g., intelligent Touch Manager)
5
To instruct specific operation with an external input coming from a
central control the external control adaptor (DTA104A62) can be
used. Instructions (group or individual) can be instructed for low
noise operation and power consumption limitation operation.
6
For RXYQ-A units it is also possible to make several commission-
ing field settings through a personal computer interface. For this
operation, an optional cable is required which is a dedicated cable
to communicate with the outdoor unit. The software for the user in-
terface program can be obtained from your local Daikin sales office.
