12.1.5 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.
A. When the low noise operation is carried out by external instructions (with the use of
the external control adaptor for outdoor unit)
1. Connect the external adaptor for the outdoor unit, and then connect the external input wiring to
the low-noise operation input terminal on the terminal block (X1M). (Refer to the figure shown
below.)
2. While in Setting mode 2 , set the setting condition for set item No. 12 (Setting of external low
noise/demand operation) to YES .
3. If necessary, while in Setting mode 2 , select the setting condition (i.e., Level 1 , Level 2 , or
Level 3 ) for set item No. 25 (Setting of external low noise level).
4. If necessary, while in Setting mode 2 , set the setting condition for the set item No. 29 (Setting
of capacity precedence) to ON .
(If the condition is set to ON , when the air-conditioning load reaches a high level, the low noise
operation command will be ignored to put the system into normal operation mode.)
B. When the low noise operation is carried out automatically at night (The external control
adaptor for outdoor unit is not required)
1. While in Setting mode 2 , select the setting condition (i.e., Level 1 , Level 2 , or Level 3 ) for set
item No. 22 (Setting of nighttime low noise level).
2. If necessary, while in Setting mode 2 , select the setting condition (i.e., [ 20:00 ], [ 22:00 ], or
[ 24:00 ]) for set item No. 26 (Setting of start time of nighttime low noise operation).
(Use the start time as a guide since it is estimated according to outdoor temperatures.)
3. If necessary, while in Setting mode 2 , select the setting condition (i.e., "06:00", "07:00", or
"08:00") for set item No. 27 (Setting of end time of nighttime low noise operation).
(Use the end time as a guide since it is estimated according to outdoor temperatures.)
4. If necessary, while in Setting mode 2 , set the setting condition for set item No. 29 (Setting of
capacity precedence) to ON .
(If the condition is set to ON , when the air-conditioning load reaches a high level, the system will
be put into normal operation mode even during nighttime.)
