2.3 Night-Time Low Noise Operation and Demand Operation
2.3.1 Night-Time 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.
When night-time low noise operation is carried out automatically (External control
adaptor for outdoor unit is not required)
1. While in setting mode 2, select a night-time low noise operation level (i.e., Level 1, Level 2,
Level 3) for the item 2-22.
2. If necessary, while in setting mode 2, select a starting time of night-time low noise operation
(i.e., 8:00 PM, 10:00 PM, or 12:00 AM) for the item 2-26. (Use the starting time as a guide since
it is estimated according to outdoor temperatures.)
3. If necessary, while in setting mode 2, select an ending time of night-time low noise operation
(i.e., 6:00 AM, 7:00 AM, or 8:00 AM) for the item 2-27. (Use the ending time as a guide since it
is estimated according to outdoor air temperatures.)
4. If necessary, while in setting mode 2, set the item 2-29 (Capacity priority setting) 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 night-time.)
