CoreSense™ Diagnostics jumper settings
The last compressor in the daisy-chain must be "terminated" by moving the jumper from JP5 to JP3. For all other compressors the
jumper should remain in the default JP5 position.
JP4 should be set "1-2" if connected to an iPro rack controller. Set JP4 to "2-3" for other pack controllers. Factory setting for JP4 is
''1-2 ECT Modbus''.
Do not remove JP1. This is reserved for future use.
