JP2 Not used —
JP3 Not used —
JP4 Fixing for Cooling Only
When JP4 is set to “open”, operation mode is xed for cooling. Thermo-ON is available only by
“COOL” or “DRY” mode at indoor unit.
JP5 Selfdiagnosis For function test of the outdoor unit control PCB.
JP6 Phase detection release
Phase detection abnormaly not detected.
Release of the Momentary Power Failure between S and T phases
RAS-(3-12)H(V)N(P/C)(E)
Setting Function Details
JP1 220V power source voltage
When JP1 is set to “open”, changes value of current protection, etc., to 220V power source
voltage.
JP2 415V power source voltage
When JP2 is set to “open”, changes value of current protection, etc., to 415V power source
voltage.
However, in single phase units it becomes 200V power source voltage.
JP3 380V power source voltage
When JP3 is set to “open”, changes value of current protection, etc., to 380V power source
voltage.
However, in single phase units it becomes 200V power source voltage.
JP4 Fixing for Cooling Only
When JP4 is set to “open”, operation mode is xed for cooling. Thermo-ON is available only by
“COOL” or “DRY” mode at indoor unit.
JP5 Selfdiagnosis
For function test of the outdoor unit control PCB.
Factory default setting is open. When power ON in short condition it enters selfdiagnosis.
JP6 Phase detection release Phase detection abnormaly not detected. When short, doesn’t affect phase detection.
