4.11.3. ROTARY SWITCH SETTING
Rotary switch setting
The rotary switch is for setting the refrigerant circuit address.
Rotary switch (SW8) - - - Factory setting "0"
Rotary switch (SW9) - - - Factory setting "0"
In the case of multiple refrigerant circuits, set SW8 and SW9 as shown in the Table 4.11-15 for each refrigerant circuit.
Do not use a nonexistent switch setting combination. (Table 4.11-15)
Example: When SW8 is set to "4" and SW9 is set to "1", the refrigerant circuit address will be "20".
