To set the number of outdoor units, on the outdoor main unit control PCB set the No. of outdoor units DIP switch (S006) to1 2 3(3 units), and set the unit No. DIP switch (S007) to2 31(unit No. 1 – main outdoor unit).2. On the No. 2 (sub) unit control PCB, set the unit No. switch (S007) to321(unit No. 2).On the No. 3 (sub) unit control PCB, set the unit No. switch (S007) to1 2 3(unit No. 3).3. On the outdoor main unit control PCB, check that the system address rotary switch (S002) is set to “1” and that the DIPswitch (S003) is set to1 2“0.” (These are the settings at the time of factory shipment.)4. To set the number of indoor units that are connected to the outdoor unit to 10 on the outdoor main unit control PCB, set theNo. of indoor units DIP switch (S005) to2 31“1,” and set the rotary switch (S004) to “0.”5.
