Hi all. My wife has been asking me for a while to upgrade our spa so she can control it with an app on her phone, and I saw there is an Upgrade kit for the CP3810 from Pentair for EasyTouch, and then ScreenLogic can be added. I have an inground spa with very old single speed pumps that I am going to replace. 2 pumps, one for the filter and one for the jets. From what I've read so far online it looks like the Easytouch system really only plays well with Variable Speed Pumps made by Pentair? Is this correct? Asking because they are pretty pricey. I'm assuming the Easytouch system can control a regular single speed pump, which I can use for the Jets, but I would like a variable speed pump for the filter and don't want any communication issues. Other things that will be on the EasyTouch are a Raypak heater and a Blower. No pool on this system, spa only.
