Solar Touch by Pentair "Solar Sensor Open"

[hbv2020]

My Solar Touch control panel show "Solar Sensor Open" and will not move the automated valve to feed the solar panels. I looked at the control boxes and did not see any loose wires. Any suggestions?

Thanks

Probably a bad sensor. Probably just need to replace it.

whoops, i never actually posted this... if you have a multimeter you can use it to determine if the sensor is bad.

Dirk posted a chart in the thread linked below that shows the resistance readings for given temperatures.
Temperature probe bad?

I’m having the same issue My system was installed last year is it really possible that the sensor went bad within one year?

All I can say is yes... but check to make sure the wires are clean and making good contact with the terminal block and that the terminal block is clean and making good contact with the pins on the board.
