Hi my name isXXXXX will try and help you with your issue
From what the display is reading the unit appears to be stuck in the Sabbath mode. That is enabled and disabled by pressing the clock button for 5 seconds. So the first thing to try is press and hold the clock button for 5 seconds, that should disable the feature unless the actual control is bad. If pressing the clock button for 5 seconds does not work, unplug the unit for 5 minutes and then try pressing it again for 5 seconds. Let me know if you need any further assistance, thank you.
