7-14. Peak cut operation (for 34 model)
The current value is limited to reduce the power consumption by external input.
Peak cut level Level 1 Level 2 Level 3 Level 4
Peak cut for rated capacity
Forced thermostat
off
50% 75% 100%
NOTES:
• During defrost operation, peak cut operation becomes invalid.
• Even during the peak cut operation, the operations of current overload, economy, and low noise
are effective and the outdoor unit operates by lowest current of them.
7-15. Outdoor unit low noise operation (for 34 model)
The compressor frequency and outdoor unit fan speed are limited to reduce the operation noise by
external input.

NOTES:
• During the defrost operation, the compressor operates by the speed for defrost operation.
• Even during the low noise operation, the operations of current overload, economy, and peak cut
are effective and the outdoor unit operates by lowest current of them.
Capacity priority mode
• Operation condition
The function setting is set to 1.
• Capacity check condition
– Shortage: Compressor frequency > limited compressor frequency for low noise mode
– Enough: Compressor frequency ≤ limited compressor frequency for low noise mode
• Operation
When detecting the shortage capacity or enough capacity condition continuous 30 minutes, the
mode is changed as follows:
– Automatic switching 1 (Level 1 setting)
Enough for 30 min
Shortage for 30 min
Normal operation Low noise mode 1
– Automatic switching 2 (Level 2 setting)
