SW510
SW501
*Both SW510 and SW501
are set to “0” at the factory
setting.
*SW580 is set to “0” at the
factory setting.
• Set the address for centralized control. (Address can be set from 01 to 50.)
• SW510 sets the tens place of the address and SW501 sets the ones place of the address.
For example, to set the address to 25, set SW510 to “2” and SW501 to “5.”
* The figure to the left indicates that the address is set to “1”.
• Set different addresses to each unit in the same system.
SW No. Refrigerant Address Description
SW580 • When the MA remote controller is not used, set the refrigerant address (SW580) to “1.”
• Set the address to “0” for the interface which supplies power to the MA remote controller.
• When more than one unit of room air conditioner is operated in the group setting, set different addresses
to each unit.
* A to F of the rotary switch corresponds to the refrigerant address of 10 to 15 respectively.
