D. Wiring Check Test
Turn off power at the disconnect. Move all dip switches
in the SW1 bank to ON. When power is turned on, the
LED display will alternate the compressor frequency and
CH (check). The system will run through each unit (A,
B, and C), cycling each EEV while testing the wiring. A
successful test will be indicated by the corresponding
LED displaying a constant green (1=A, 2=B, 3=C). Mis-
wired units will generate an EC on the display, with the
corresponding LED flashing green.
