I have a SolarTouch system. I have it set so it does not control the pump, cooling and freeze protection are off.
I have noticed lately that the solar is running all day so I started watching the temps today.
I had the target temp at 80* and the water temp was 80* with the solar running. I turned the target temp down to 79* and the solar shut off. But 15 minutes later the solar came back on and when I looked at it the target temp was still 79* and the water temp 80*.
Any idea why this would not be shutting the solar off when it reaches the target temp?
