Ok
Point to note if it blows the fuse you have mixed up the neutral wires.
If the system still fails to work with the link in the problem is else where.
It is a straight forward job for a experienced engineer 30 mins if only the timer change. But if other problems exist the who knows.
The correct terminals for the new clock are as follows n=neutral, L+live 3 = hot water ON and 4 = heating on. If you have a gravity hot water system you need to check the switch setting on the back of the timer is set to gravity as both the heating and hot water have to run together for you to get heating.
