Peak cut operation
„ z
Peak cut mode (Optional parts: UTY-XWZXZ3)
The introduction of a peak power consumption mode control 4 steps outdoor operation control to
cut down energy usage at peak energy usage times.
* Performance drops by reducing the power consumption preferentially.
Level 1 ... Performs operation which suppresses the power consumption to the rated power
consumption value (100%).
Level 2 ... Performs operation which suppresses the power consumption to 75% of the rated
power consumption value.
Level 3 ... Performs operation which suppresses the power consumption to 50% of the rated
power consumption value.
Level 4 ... Performs operation which suppresses the power consumption to almost 0% by stopping
the compressor.
