SiUS342303E Field Setting from Outdoor Unit
Part 5 Field Settings and Test Operation 194
2.4.3 Details of Setting Mode 2
Mode 2 is used to change the field settings of the system. Consulting the current field setting value
and changing the current field setting value is possible.
In general, normal operation can be resumed without special intervention after changing field
settings.
Some field settings are used for special operation (e.g. 1 time operation, recovery/vacuuming
setting, adding refrigerant setting, etc.). In such a case, it is required to abort the special operation
before normal operation can restart. It will be displayed in below explanations.
[2-0]: Cool/Heat selection setting
Cool/Heat selection setting is used in case the optional Cool/Heat selector
(KRC19-26A) is used. Depending on the outdoor unit setup (single outdoor unit setup or
multi outdoor unit setup), the correct setting should be chosen. More details on how to
use the Cool/Heat selector option can be found in the manual of the Cool/Heat selector.
Default value: 0.
 0: Each individual outdoor unit can select Cool/Heat operation (by Cool/Heat selector
if installed).
 1: Master unit decides Cool/Heat operation when outdoor units are connected in
multiple system combination
 2: Sub unit for Cool/Heat operation when outdoor units are connected in multiple
system combination
Change [2-0] to 0, 1 or 2 in function of required functionality.
[2-1]: Cool/Heat unified address
Address for cool/heat unified operation.
 When multiple heat pump systems need to change over together between cooling
and heating (example multiple systems serve indoor units in landscape area). Per
zone the optional PCB DTA104A62 needs to be installed. Recommended location is
in one of the
VRV indoor units belonging to the system that will be set as “Master
cool/heat unit” (field setting 2-0-1).

The address set to the multiple systems need to operate as a zone, should be
same as the address set by the DIP switches on the related optional PCB
DTA104A62.
