Hi Lisa, this is my first post but I've been using TFPC for a long time - and it has given me the confidence to fire our PB this week after getting really frustrated that they aren't maintaining the PH, CYA, TA, Salt, Filter or really anything. I've had 2 algae outbreaks in the 2 years since we moved in - one because the filter was clogged enough that the SWG was showing "Low Flow" and therefore chlorine dropped to zero when I was on a business trip, and the other when the salt dropped really low after heavy rains, and again the SWG couldn't make chlorine.
When the SWG is connected to the Easytouch, the buttons on the SWG don't do anything. The SWG output percentage is controlled by the Easytouch. Do this:
On the EasyTouch (or your EasyTouch remote control) go to Menu->Settings->Intellichlor and then you can set the output percentage to 0% on pool mode. Don't choose "Enable: No" because that doesn't actually turn it off, it just disconnects the control between the EasyTouch and the IC40.
Also, regarding the pressure increasing when your booster pump is running - Maybe the Easytouch is programmed to run the main pump at a higher speed when your booster pump is running, and that is causing the filter pressure to be higher? If you want to see the IntelliFlo pump speed while it is running, go to Menu->Settings->Intelliflo->Pump #1->Status
