DSW5: Setting of end-terminal resistance
It is not necessary to set when the number of RASC units in the
same H-LINK line is one. In case of more than one RASC unit in
the same H-LINK line, set as follows:
• First RASC unit: keep DSW5-1 in “ON”.
• Rest of RASC units: set DSW5-1 to “OFF”.

400V power source voltage
When JP3 is set to “open”, current protection parameters are set for a 400 V power source voltage.
JP4
Fixing for Cooling Only
When JP4 is set to “open”, operation mode is fixed for cooling. Thermo-ON is available only by “COOL” or
“DRY” mode at indoor unit.
JP5
Self diagnosis
For function test of the RASC unit control PCB.
Factory default setting is open. When power ON in short condition it enters self diagnosis.
JP6
Phase detection release
Phase detection abnormality not detected. When short, doesn’t affect phase detection.
