Field Settings for Outdoor Unit (6/8 HP Models)
Part 5 Field Settings and Test Operation

3.6.3 Details of Setting Mode (Mode 2)
Mode 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 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.
Mode 2-5:
Cross wiring check.
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.
Mode 2-6:
Forced thermostat ON
command all connected indoor units.
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 2-6-0. Once setting 2-6-1 is active, it is not automatically
returning to default when exit mode 2.
Mode 2-8:
Te target
temperature for cooling operation. Change the setting in function of
required operation method during cooling. (Mode 2-23 should be 1 or 3)
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.
Mode 2-11:
Eco level setting for Eco mode via External control adaptor (Optional).
Eco mode can be activated by short circuit the terminal on External control adaptor
(Optional) according to 2-11 setting. (2-23 should be “0”)
This unit can operate with “Te fix control” and “Eco mode”.
Eco mode means “VRT” & “VRTsmart” control
If the terminal on external control adaptor is not connected by short circuit and 2-11 is not
0, the system operates according to 2-8 setting.
