9-1. Indoor unit
DIP switch and jumper connector functions.
Each function is controlled by the jumper connector in the controller board. Below table shows that the function setting by the
jumper connector is available or not in the controller board of applicable units. Also J11~15 (SW1) and J21~24 (SW2) has Dip
switch with their jumper connector.

Note 1: If the settings of SW1 (model settings) or SW2 (capacity settings) on the service PCB are made incorrectly:
•If the SW1 settings are made incorrectly, the unit will not operate, or won't be able to operate normally.
•The SW1 (model) and SW2 (capacity) settings are used to send the indoor unit's model and capacity
information to the outdoor unit. The outdoor unit uses this information to perform control, so the expected
performance may not be achieved if the information is incorrect.
•In models with indoor fan phase control, pulsation control or DC fan control, the SW2 (capacity) settings are
used to control the fan air volume. If the settings are made incorrectly, the air volume may be higher or lower
than expected, performance may drop, or the noise level may increase.
