We just had an EasyTouch, Intelliflo, IntellipH, SCG, and new filter installed. The pump is an upgrade from a single speed. If I run the pump below 1350 RPMs, the blower on the heater kicks on, and I get the "lo" error message that usually means low water flow. This happens at less than 1350 RPM and when the pump is off. The heater is an old Hayward H400IDL2 installed around 2005/2006.
Any ideas? I guess my next step on my end is to disconnect the remote wire just to see if it's an interface issue.
Thanks for any replies and suggestions.
