Field Setting from Outdoor Unit
[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 DTA104A61/62 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 DTA104A61/62.

connections A-B-C to optional PCB "BRP2A81".
[2-2]: Low noise/demand address
Address for low noise/demand operation.
1 or more systems (maximum 10 systems wired by "F1F2 OUT/D") can operate use the LNO (Low Noise
Operation) or/and the DE (Demand Control) by instruction of field supplied input to optional PCB
DTA104A61/62.
To link the system to the corresponding DTA104A61/62, set the address same as the DIP switches
position on the related optional PCB DTA104A61/62.
Ensure that also field setting 2-12-1 is set to enable input from optional PCB DTA104A61/62.
[2-5]: Cross wiring check
Default value: 0. Not active.
Set 1: force all connected indoor units to operate the indoor fan on high speed. This setting can be made
to check which units are missing in the communication if the number of indoor units do not correspond to
the system lay out. Ensure that after cross wiring check was confirmed, to return setting to default 2-5-0.
Once setting 2-5-1 is active, it is not automatically returning to default when exit mode 2.
[2-6]: Forced thermostat ON command all connected indoor units
