Hi all,
I am having issues with my Horstmann C27 which keeps blowing the 5 amp consumer fuse. Used to have the Horstmann C17 before and had been working for a few years. One day when I used the Boost button it tripped the 5 amp fuse and screen went blank. Replaced the fuse but it kept blowing the fuse. Sometimes would go for 5 minutes, sometimes 10 minutes, sometimes half an hour, radiators heat up then at a random time the fuse would blow. Sometimes can have it come on for an hour and go off at a specified time without tripping but the next time I use it, it trips.
Thought it was the control panel so changed from C17 to C27. C27 is tripping fuse out as well. Attached is a simplified version of the way i have the back panel wired at the moment. Does it look right to you? Do I need to add other connections?
I know the C27 is a dual channel device for Hot Water and Central Heating but I only need the Central Heating side working.
My dad knows a bit about electrics and has separated the heating system onto it's own circuit but still tripping as I say.
Anyone any ideas as to why it might be tripping? Possibly a break in the wiring somewhere? What would be the cheapest way to get this fixed? Use a remote timer panel?
