operate.
3) The display will change to a steady “c” or “C” to show
the current command for unit operation.
NOTE:
If a command for unit operation is present
at the end of TEST mode will cause the unit to continue to
operate.

If no command for unit operation is present, TEST mode
causes the following:
1) A steady “c” appears on the dual 7-segments LEDs.
2) The compressor will start.
