I purchased a Superflo VS pump and have an Easytouch 4.  Unfortunately 3 of the relays are being used so I can't program the pump's variable speeds through the controller.  What is the best practice as far as the pump prgroam time on the Eastytouch versus the custom program on the pump?  Is it a problem to turn off the pump power for 12 hours a day through the Easytouch program timer?  I'm concerned over time that the Superflo will lose its program due to having to rely on its own battery to store the program.
