I have a th8000 that is locked up. I have tried new batterys I have also tried to pull the memory battery out and still nuthin I bought this house about 6 months ago and it came with it, is there any way of getting it unlocked, these aren't cheap units if not ill go with something else, also does any one know what the wiring diagram is for this unit? I have the ususal wiring and then there are wires on s1 and s2 what are those for? I am a electrician so I am familiar with this stuff but I can not find a diagram on this unit thanks
