Notes:

1.Step 1 is Hot Gas Bypass and is skipped when loading occurs. Hot Gas Bypass operation is inhibited during Pumpdown. For Leaving Chilled Liquid Control the Hot Gas Bypass solenoid is energized only when the lead compressor is running and the LWT < SP, the Hot Gas Bypass solenoid is turned off when the LWT > SP + CR/2

2.Step 3 is skipped when loading occurs.

3.Step 4 is skipped when unloading occurs.
