Hi Joe ~ I assume that you have carried out the holding in of the +- buttons for 3 seconds and then released them and done it again? If so have you carried out a reset? ~ Ian

OK well as you are aware even if this doesn't work the board cancels the test mode after 15 minutes anyway, if this is not happening I would suggest that You have a faulty board ~ send it back and get it replaced. What was the original fault?
Customer: replied 2 years ago.

The original PCB was stuck in summer mode, the button mounted in the PCB to take it out of summer mode was faulty

Expert:  Dales-Electronic replied 2 years ago.
If it were me I would do it this way if you can, take out the board again and check that all the wiring connections are sound and then with the board still out and making sure it cannot short out anywhere press the small microswitches that equate to +- see if you can cancel test mode with the board out. If you can then you have a further problems with the buttons, if you cant then its the pcb ~ remember you are working with voltages in part that can bite ~ Ian
