Rainsoft Cycles, What are they? (Q2, Model AQ40CCT)

We have a Rainsoft Q2, AQ40CCT (That's what is on our purchase agreement from March 1996).
I would like to know what the 9 Cycles are during regeneration.
#1 is 25 Minutes
#2 is 120 Minutes
#3 is 15 Minutes (Seems to go to the Sewer Drain)
#4 is 3 Minutes
#5 is 40 Minutes (Seems to go to the Sewer Drain)
#6 is 15 Minutes
#7 is 40 Minutes (Seems to go to the Sewer Drain)
#8 is 1 Minute
#9 is 15 Minutes (Seems to go to the Sewer Drain)
It goes through all the cycles. The motor works and the Piston Assembly moves as it should.

It was not using any salt. I read that you should be able to blow through the Brime Refill Seat. I removed the screen and got the seat cleared so that I could blow through it. It now allows water to go into the Salt Container.
It seems to be working.

The # 2 Cycle seem to do nothing for 120 Minutes. Do I have a problem? What does this cycle do?

Have a good day.
