 Problem with UFH | |
I was doing some work at a customer's house today and she asked me to program her underfloor heating as she hadn't got around to it. (I didn't fit the UFH)
I switched the stat on (warmup t-stat), set the time, put the other info in etc. As soon as I asked it to start warming up it kicked in and blew the fuse.
Has anybody come across this before or know why the fuse would blow?
