I have an IC40 and Easy Touch 4 Panel and live in Canada so pool season is from May to October. My Easy Touch salt reading are either Salt OK 3550 PPM No Errors (corresponds to a green light on IC) or 2750 PPM Low Salt (orange light on IC). I have never had a reading in between (in 50 ppm increments) as the manual says which is why I bought it. I have been back and forth with PB and Pentair Support as of late. First for a Firm Ware Upgrade (Pentair rep came out, upgraded firmware). I was then told to clean cell with m acid, etc in case of build up.
History: Got my IC40 and Easy Touch Panel unit in fall 2006, installed in May 2007 (last year), had problems and waited around for the PB to get me a new unit which he promised. This never happened to address the problem. This year I went straight to Pentair but still no replacements or proper repair. They are telling me my Firmware is still wrong and needs to go to V2.0. I have V1.05. They are telling me I need more diagnostics before they will replace either the IC 40 cell or the LED screen/circuit board on the Easy Touch.
My IC40 seems to work although I did have to recalibrate (it is a V1.6).
All else works with Easy Touch. IC controls my water well and it is generally perfect even through torrential downpours we've had in July other than having to add some salt.
Has anyone had any similar problems with IC communicating with Easy Touch?
Frustrated with Easy Touch!
