I bought a cheap T12 & Jbc245 controller board, a pre assembled C245 handle, and a couple c245 tips from aliexpress, but have already ran into problems.
First power up and the c245 tip got bright red no matter what the temp was set at.
I contacted the seller and they said "incorrect wiring" but of course didn't elaborate or tell me the correct way to wire.
Looking at the controller board with the GX12 connector facing me and the notch on top going counter clockwise I have it wired 5. + Red wire, 4. (should be ground but my handle doesnt have a black wire so I am confused) Jumper wire from it to pin 3, Pin2. is the blue wire for temp sensor and pin 1 is supposed to be a white wire for sleep detection, but is empty because my handle doesnt have sleep detection...does this sound right?
thanks
