I have an RJ60 I installed in 2012 which has worked great so far. Just had a lot of algae form in pool while gone for a week, checked chemistry and found CL level was zero although CircuPool output was at 100% and CL level was fine 2 weeks prior. Stepping through screens found it was reading water temp of 32 deg when actual was 62 deg. Sent vendor a message asking about parts or recalibration procedure, but don't expect any reply till after weekend. Anyone out there with any similar experience and solutions?
