[2-26]= Low noise operation start time
Change [2-26]=1, 2 or 3 in function of required timing.
Default value=2.
Value
[2-26]
Start time automatic low noise
operation (approximately)
1
8:00 p.m.
2
10:00 p.m. (default)
3
12:00 a.m.
This setting is used in conjunction with setting [2-22].

Default value=3.
Value
[2-27]
Start time automatic low noise
operation (approximately)
1
6:00 a.m.
2
7:00 a.m.
3
8:00 a.m. (default)
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 run under power consumption limita-
tion conditions when an external signal is sent to the unit,
this setting defines the level power consumption limitation
that will be applied for step 1. 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.
Value
[2-30]
Power consumption limitation
(approximately)
1
60%
2
65%
3
70% (default)
4
75%
5
80%
6
85%
7
90%
8
95%
[2-31]= Power consumption limitation level (step 2) via the external
control adaptor (DTA104A61/62)
If the system needs to run under power consumption limita-
tion conditions when an external signal is sent to the unit,
this setting defines the level power consumption limitation
that will be applied for step 2. The level is according to the
table.
Default value=1.
Change [2-31]=1, 2 or 3 in function of required limitation.
Value
[2-31]
Power consumption limitation
(approximately)
1
40% (default)
2
50%
3
55%
[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 run under power consump-
tion 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).
Value
[2-32]
Restriction reference
0
Function not active (default)
1
Follows [2-30] setting
2
Follows [2-31] setting
Change [2-32]=0, 1 or 2 in function of required limitation.
[2-34]= Indoor unit fan tap setting
Indoor units fan speed limitation related to connection ca-
pacity and outdoor air temperature for energy saving.
Default value=0.
Value
[2-34]
Indoor unit fan tap setting
0
Fan speed is limited to L tap when indoor units
capacity ≥130%.
1
In heating mode, fan speed is limited to L tap
when indoor units capacity ≥130%.
2
Fan speed follows the setting of remote controllers
(not limited by indoor units connection capacity).
See the service manual for other indoor unit fan tap settings.
[2-35]= Height difference setting
Default value=1.
In case the outdoor unit is installed in the lowest position
(indoor units are installed on a higher position than outdoor
units) and the height difference between the highest indoor
unit and the outdoor unit exceeds 130 ft. (40 m), the setting
[2-35] should be changed to 0.
Other changes/limitations to the circuit apply, for more infor-
mation see 7.5. System piping (length) limitations on page 11.
[2-45]= Low ambient cooling
Default value=0.
Value
[2-45]
Description
0
No low ambient cooling available.
(default)
1
Low ambient cooling available.
This setting is not applicable to multi Branch Selector unit
(BS4-12Q54T type).
For more information about this setting, refer to the service
manual.
