I have had the unit up and running for a month, the only issue was the fact that the instructions show a J3 connection for relay use and I figured out that a J4 connection is needed.
The device stopped working last night and will not show the display unless I change the jumper from J4 to j3, Is this a blown diode? If so can you tell me the value so I can source it?
Thanks in advance!
