By performing the following modification, operation noise of the outdoor unit can be reduced by about 3-4 dB.
The low noise mode will be activated when a commercially available timer or the contact input of an ON/OFF switch is added to
the CNDM connector (option) on the control board of the outdoor unit.
• The ability varies according to the outdoor temperature and conditions, etc.
