The outdoor unit is equipped with a preheat defrost operation
that raises the discharge temperature of the air before beginning
defrost operation. This contributes to raising the room
temperature before the start of defrost operation and prevents
room occupants experiencing a chilling sensation.

Operation time

Smooth auto-shift startup mode, an operation mode on the
outdoor unit, can now be selected in addition to the conven-
tional COP Priority and Capacity Priority modes. In order to
heat the room faster, Capacity Priority mode runs for 30
minutes when heating operation starts. The unit then switch-
es to COP Priority mode to increase energy-saving efficiency.
This enables both improved comfort and energy savings.
* Time for preparation for heating is required.
* Each mode is activated when the ambient temperature is below the specified
temperature. For details on the settings, refer to the Data Book.

This mode reduces noise by limiting the compressor frequency and the number of rotations of the outdoor fan (for the
air-cooled outdoor unit).
The user can select a preferred level.
*Cooling/heating capacity drops during low-noise mode operation.

The operation pattern under low ambient temperature conditions can be selected and the priority mode setting
(“Capacity priority mode” and “COP priority mode”) can be switched with the function settings.
Each mode is activated when the ambient temperature is below the specified temperature. For factory settings, refer to
the Data Book.
• Examples of sound pressure level in low noise mode (PUHY-P200YNW-A1 <cooling>)
Sound pressure level with 100% fan
rotation and compressor frequency
Sound pressure level with 50% fan
rotation and compressor frequency
When Low noise mode is set, "Performance-priority mode" and
"Quiet-priority mode" can be selected. When "Performance-priority
mode" is selected, the system automatically returns to normal
operation in cases of heavy operating conditions.
