E 3 error message?

I'm testing one of these as you mentioned, by directly injecting 6.3V DC without mains connected. It seems to be working, except I'm getting a flashing "E 3" on the LCD intermittently. After a brief scan through the code, I can't see right off what generates E3.

The relevant source is here. It means an "OC fault" (open circuit) from the temperature sensor. See the table on page 10 of the datasheet.

Thanks, Andy. That did the trick. All's working fine now.
