Ham,
OK, did a little more research and it appears that the Superflo can be controlled by Applying 5 volts to one of four input wires. This lets you select one of four possible pre-set speeds. To do this, the Superflo outputs 5 volts which goes to your control system (in your case the Easytouch). This five volts gets applied to the input side of 4 (yes four) AUX relays. Energizing the relay will apply the 5 volts back to the Superflo selecting that speed. The downside is that the Superflo can only use one input at a time and if more than one input is applied it will select which input to use based on an internal priority system.
So Ham, some questions for you..
1. Do you have an EasyTouch 4 or 8? My guess is an 8 as I can't see how this could work on a 4 with a SWG
2. When you say you changed your schedule, what did you change? Sounds like you changed the pump run time from 24 hours to 12 hours which, if wired correctly, would account for the pump/filter relay turning off, which would also shut off the SWG. But I can't see how any of that controls your pump speed. So I suspect there is a corresponding AUX relay that is still on telling the pump to run at whatever speed you had previously selected.
Of course, I am fumbling in the dark and I've been wrong many times before (just today), so your mileage may vary. Any hope of getting a picture of your panel with the CB cover off showing all of the relay wiring?
Thanks,
Jim R.
