Hi all, we installed solar few years ago and last season when we turned it on the temperature setting is backwards, so In order for it to heat I have to turn the desired temp lower than the pool temp….im not sure how it happened I don’t know why they make this thing so complicated. Does anyone one know what could be the cause? We have the pentair solar touch, I called the company who installed it and they charge a 200$ fee to come out and service it.
