INFORMATION
Not all combinations of indoor units are allowed. For guidance, see
1.2. Combinations and options.
1.2. Combinations and options
The VRV Aurora series heat recovery 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 Aurora series.
NOTE
To be sure your system setup (outdoor unit + Branch Selector unit(s)
+ indoor unit(s)) will work, you have to consult the latest technical
engineering data for VRV Aurora 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 units use, combinations between indoor
units, etc.) mentioned in the technical engineering data.
The Branch Selector units that combined with RELQ-T units for
changing the refrigerant flow to indoor units are T type
(BSQ-T
*
, BS-Q54T
*
, BSF-Q54T
*
) only. Do not combine the T type
and P type (BSVQ-PVJU, BSV-Q36PVJU) in the system. Combination
of T type and P type cause malfunction.
1.2.1. Indoor units combinations
In general VRV indoor units can be connected to RELQ-T units.
1.2.2. Outdoor units combinations
Aurora Series combination for RELQ-T units are as indicated in tables
below (and right), where RELQ 144-240 consists of multiple RELQ
72-120 single modules as indicated.

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)
4
To instruct specific operation with an external input coming from a
central control the external control adaptor (DTA104A61/62) can
be used. Instructions (group or individual) can be instructed for low
noise operation and power consumption limitation operation.
5
For RELQ-T units it is also possible to make several commissioning
field settings through a personal computer interface. For this option
999482P3 is required which is a dedicated cable to communicate
with the outdoor unit. The software for the user interface program
can be obtained from your local Daikin sales office.
INFORMATION
Refer to the technical engineering data for the latest option names.
