Stonegate programmable step controller

Hi All
I am looking for a more detail on the stonegate controller.
I have the basic pdf off the stonegate website but would really like more detail on controlling setup of three compressors with this controller.

Which model controller have you got. This sort of information helps get better answers.

Supposing the three compressors are the same, set the dipswithes like this
000000
000001
000011
000111
and the last step is n.4

If the three compressors are different (1 smaller than 2 smaller than 3), then setup like this
000000
000001
000010
000100
000101
000110
000111
and the last step is n.7

Control is done via a differential pressure switch. When the switch recognize an increase in pressure, the controller reduces capacity, the otherway when pressure reduces. When pressure settles in the neutral zone, capacity is kept in position.
