Brian,
It would help if we knew how they were plumbed..
The only thing the EasyTouch can do is increase or decrease the pump speed. Depending how the valves are plumbed, the EasyTouch can turn them on or off, but it can't control the amount of flow other than by pump speed. If they are controlled by an automated Jandy valve, it will be either all on or all off, electrically there is no in-between position. Mechanically you can adjust the valve's open and closed positions, but the ET can only drive it from one end to the other.

Edit.. I assume your bubblers are controlled by the three red valves labeled as 1, 2, and 3??? If so, what are the positions of the two Jandy valves in between the red handle valves and the SWCG?
