Look at page 7 of this manual. It is the Rosetta stone you are looking for. It will identify the terminal in the control box that should be energized for each step of the process for retracting the room. It is actually easier than that because if you will match terminal number to LED number, the yellow LED will light if that part of the sequence is triggered, and the red LED will light if the relay actually provides voltage to the corresponding solenoid.
