Test Operation
3.2.2 Setting of Low Noise Operation and Demand Operation
Setting of Low Noise Operation
By connecting the external contact input to the low noise input of the outdoor unit external
control adaptor (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 outdoor unit external control adaptor)
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 PCB, 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 PCB, 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 outdoor unit
external control adaptor is not required)
1. Set “Night quiet mode setting” on the outdoor unit PCB. (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 quiet mode start setting” on the outdoor unit PCB, 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 quiet mode end setting” on the outdoor unit PCB, 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.)
4. Set “Capacity precedence setting” on the outdoor unit PCB, as the need arises.
(Set by Setting Mode 2)
(If set to “ON”, when air conditioning load gets higher, the status is switched to normal
operation even at night.)
