8. CIRCUIT BOARD SETTING
Set the switch on the circuit board.
(1) Indoor unit addresses
Rotary switch (SW5) - - - Factory setting "0"
When connecting multiple indoor units to one refrigerant system, set the address at SW5 in sequence from 0.
(2) Refrigerant circuit address
Rotary switch (SW7) - - - Factory setting "0"
Rotary switch (SW8) - - - Factory setting "0"
In the case of multiple refrigerant systems, set SW7 and SW8 as shown in the Table 7 for each refrigerant system. Set to the same
refrigerant circuit address as the outdoor unit.
Example: When SW8 is set to "1" and SW7 is set to "14", the refrigerant circuit address will be "30".
