easytouch and solar problem

[Acho]

Hi all,

I have strange problem with my easytouch regarding solar heating operation.

I set the target temp as 86F/30C, pool temp is 86F/30C, Air temp is 92F/33C, Solar temp is 107F/38C, start temp is 6F/4C, run temp is 3F/2C.

Once the target temp is reached the solar valve and pump speed switch to solar ON and solar OFF in cycles like few minutes even if the water temp stays the same / +/- 1 /.

All the temp sensors are calibrated as good as I can and I am running the system to show the temps in Celsius if that makes any difference.

This drives me crazy since I have no control over it

Any help is appreciated

Thanks
