Setting of Low Noise Operation
By connecting the external contact input to the low noise input of the external control adapter for
outdoor unit (optional), you can lower operating noise by 2-3 dB.
A. When the low noise operation is carried out by external instructions (with the use
of the external control adapter for outdoor unit)
1. Set “External low noise / Demand YES/NO setting” to “External low noise / Demand YES”.
(Set by Setting Mode 2)
2. Set “External low noise level setting” on the outdoor unit PC board, as the need arises.
(Lower noise operation can be carried out by “Mode 2” than by “Mode 1”, and by “Mode 3”
than by “Mode 2”.)
3. Set “Capacity precedence setting” on the outdoor unit PC board, as the need arises.
(If set to “ON”, when air conditioning load gets higher, the low noise instructions are
neglected to switch to normal operation.) (Set by Setting Mode 2)
B. When the low noise operation is carried out automatically at night (The external
control adapter for outdoor unit is not required)
1. Set “Night-time low noise setting” on the outdoor unit PC board. (Set by Setting Mode 2)
(Lower noise operation can be carried out by “Mode 2” than by “Mode 1”, and by “Mode 3”
than by “Mode 2”.)
2. Set “Night-time low noise start setting” on the outdoor unit PC board, as the need arises.
(Set by Setting Mode 2)
(Since the time is presumed in accordance with the outdoor temperature, the starting time is
a target only.)
3. Set “Night-time low noise end setting” on the outdoor unit PC board, as the need arises.
(Set by Setting Mode 2)
(Since the time is presumed in accordance with the outdoor temperature, the ending time is
a target only.)
