Thanks, the "hot water off" could be a good shout, I think I spotted a signal wire between the controller and the boiler that matches that, I wonder if that's not happy for some reason.

I didn't know the exact model number, but yes looking at pictures online, it's a Camray 5 Combi 55 or 70, yes. It's not that it's giving priority to the hot water, it's that it's heating the tank when the hot water is marked as off. Which seems like a waste of oil?

Apologies if this is an already answered question, I did check the Wiki and the FAQ, but nothing quite lines up. We've got an oil fired boiler (an ancient Camray 5) that has an integrated 12 litre hot water tank for DHW. The original system only had a Summer / Winter switch on it, no controls...
