PeterJames 499 Posted March 1 (edited) Hi Tracey Welcome to the forum. That panel is probably DIY and it is quite old, the default user code is ##REMOVED## if that doesn t work then you need to get a company in to default it if you can find someone that will support that panel now. It is likely that it hasnt been serviced in a while and so its best to get someone to look at it anyway, if you start using it and it goes faulty it can allsorts of problems with your new neighbors Edited March 10 by sixwheeledbeast Quote Share this post Link to post Share on other sites
