Suprima 50 - blowing 2 amp fuse

[Splat5]

I have just changed my room thermostat, and when I turn the dial all the way on the new one, it blows the 2 amp fuse.
If I dont turn the dial all the way, the system works fine, and doesnt blow.
The boiler is a Suprima 50. and the new room thermostat is just a standard Wikes one.

Any ideas what is causing it,
and anyone know where I can get the 2 amp fuses from in London (city/central)

Thanks
