Does anyone know what the problem is with this Potterton 30L boiler? both lights for hot water and central heating are on at the programmed time but only the hot water is working, there is no central heating. I looked at the diagnosis guide and it says "check the 10/16 interlock setting. (for simple systems). See installer's Guide instruction."
Problem is I don't have an installer's guide. Does anyone know where the 10/16 interlock setting is? Would very much appreciate your help.[/u]
