Thanks for the pics. They help alot.
I would go with the instructions printed on the unit rather than the paper ones.
The temperature probe is not polarity conscious, as stated in the instructions and as long as you have one leg in terminal 9 and the other in terminal 10 you'll be right. I'm confident this is not your problem.
The way in which your heater is currently connected will not allow the SF 800 to switch it on and off, hence the reason it is not cutting out. No biggie. You can sort that with a quick re-wire.
The way in which yhou have terminals 2 and 3 connected is a worry though. If the unit has an internal connection between terminal 2 and 3 it will produce a dead short. The diagram on the unit doesn'd say what terminal 3 is used for so it may just be a spare, in which case luck is on your side. In any event do not re-power the unit as currently connected as damage may result.
At the moment I think you have two problems. One, the connections to the terminal block. Two, this is a guess but probably the original problem and the cause of your frustrations, programming. Once we get the wiring sorted out the programming should be easy enough to nut out with a bit of trial and error. For future referrence, for yourself and others and I'm not having a go here, trial and error isn't a good approach to wiring as irreparable damage is a common outcome.
If you can bear with me I'll draw you a little picture and attempt to upload it.
