stands for
system error
. That means in spite of the pump running there is a difference in temperature of more than 80
Kelvin measured between collector and storage tank. The reason for such a huge temperature difference could be a damaged
or faulty connected pump, a closed valve or air in the solar circuit. As air inside the piping can’t be overcome by a conventional
pump, circulation of the solar circuit is stopped. Check your solar-system for these sources of error to avoid damages.*
You can quit the error message afterwards by pressing any key.
If the trouble shooting does not solve the problem then contact your local Solar qualified Engineer.
