Better get rid of whole thing , it's old scrap does a job temporarily, and if you have DIY skilz then install a scantronic ion 40
But depends on wiring if it's one of those galaxy that been installed with a common leg of sorts then don't bother you will get stuck
I guess I want to know when you enter your code and press B it gives you option for part of night set
Or it does something else, will give idea what panel you got
And maybe we blag our way through it
No for another discussion lol don't be scared
All seemed correct except the link in the panel removed that
The link goes in the bell for 0v to tmf
Then tmpr white or green doesn't matter goes to the panel bell tmpr , as in leave white where it is and remove the black link in panel
If that makes sense
