Setting Function Details
JP1 Not used —
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 Self-diagnosis 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 230V power source voltage
When JP1 is set to “open”, current protection parameters are set for a 230 V power source
voltage.
JP2 Not used
JP3 400V power source voltage
When JP3 is set to “open”, current protection parameters are set for a 400 V 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.
4.3.4 LED’s indication
LEDIndication
LED1 Red This LED indicates the transmission status between the indoor unit and the RCS
LED2 Yellow This LED indicates the transmission status between the indoor unit and the outdoor unit
LED3 Green Power source for the PCB
