2.6.2 Details of Setting Mode (m2)
 m2-2: Low noise/demand address: address for low noise/demand operation.
 m2-5: Cross wiring check.
 m2-6: Forced thermostat ON command all connected indoor units.
 m2-8: Te target temperature for cooling operation. Change the setting in function of required
 m2-12: Enable input "DTA104A61": enable the low noise function and/or power
 m2-13: AIRNET address.
Part 5 Field Settings and Test 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 board DTA104A61/62.
 To link the system to the corresponding DTA104A61/62, set the address same as the
DIP switches position on the related optional board DTA104A61/62.
 Ensure that also field setting 2-12-1 is set to enable input from optional board
DTA104A61/62.
 Default value: 0. Not active.
 Set 1: force all connected indoor units (except VKM) 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.
 Default value: 0. Not active.
 Set 1: force all connected indoor units to operate under "Test" (forced thermostat ON
command to outdoor). Ensure that when the forced thermostat ON needs to be ended, to
return setting to default 26-0. Once setting 2-6-1 is active, it is not automatically returning
to default when exit mode 2.
operation method during cooling.
 Default value: 2 (Te target: 6°C). The refrigerant temperature is fixed to average indoor
evaporating temperature of 6°C, independent from the situation. It corresponds to the
standard operation which is known and can be expected from/under previous VRV
systems.
 Set 3-7: High Sensible. The refrigerant temperature is set higher/lower in cooling
compared to basic operation. The focus under high sensible mode is comfort feeling for
the customer. The selection method of indoor units is important and has to be considered
as the available capacity is not the same as under basic operation. Activate this setting
under cooling operation.

consumption limitation. If the system needs to be running under low noise operation or under
power consumption limitation conditions when an external signal is sent to the unit, this
setting should be changed. This setting will only be effective when the optional external
control adaptor for outdoor unit (DTA104A61/62) is installed and the address set by DIP
switches on DTA104A61/62 corresponds to the address set on the outdoor unit(s) – set 2-.
 Default value: 0.
 To enable input from DTA104A61/62 change to 2-12-1.
 When an AIRNET system will be used, outdoor unit needs an AIRNET address.
 Also to facilitate the recognition of a system in the map lay out of the service checker type
III, set each system a unique address between 1 and 63.
 When duplicating of AIRNET address, UC error code will appear on central control.
