[2-25]= Low noise operation level via the external control
adaptor
If the system needs to be running under low noise
operation conditions when an external signal is sent to
the unit, this setting defines the level of low noise that
will be applied (3: Level 3<2: Level 2<1: Level 1).
This setting will only be effective when the optional
external control adaptor (DTA104A61/62) is installed
and the setting [2-12] was activated.
Default value=2.
To activate function change [2-25]=1, 2 or 3.
[2-26]= Low noise operation start time
Change [2-26]=1, 2 or 3 in function of required timing.
Default value=2.
This setting is used in conjunction with setting [2-22].
[2-27]= Low noise operation stop time
Default value=3.
This setting is used in conjunction with setting [2-22].
[2-30]= Power consumption limitation level (step 1) via the
external control adaptor (DTA104A61/62).
If the system needs to be running under power
consumption limitation conditions when an external
signal is sent to the unit, this setting defines the level
power consumption limitation that will be applied for
step1. The level is according to the table.
Default value=3.
Change [2-30]=1, 2, 3, 4, 5, 6, 7 or 8 in function of
required limitation.

[2-31]= Power consumption limitation level (step 2) via the
external control adaptor (DTA104A61/62).
If the system needs to be running under power
consumption limitation conditions when an external
signal is sent to the unit, this setting defines the level
power consumption limitation that will be applied for
step2. The level is according to the table.
Default value=1.
Change [2-31]=1, 2 or 3 in function of required
limitation.
[2-32]= Forced, all time, power consumption limitation operation
(no external control adaptor is required to perform
power consumption limitation).
If the system always needs to be running under power
consumption limitation conditions, this setting activates
and defines the level power consumption limitation that
will be applied continuously. The level is according to
the table.
Default value=0 (OFF).
Change [2-32]=0, 1 or 2 in function of required
limitation.
[2-73]= When the system is using non-R410A VRV DX indoor
units, the system needs to get the proper input
according to the table below.
Default value=0
[2-81]= Cooling comfort setting.
Default value=1
Change [2-81]=0, 1, 2 or 3 in function of required
limitation.
This setting is used in conjunction with setting [2-8].
