Fuse blowing sounds like a dead short, have you got a neutral connected wrong somewhere?.....for example at your room stat or one of the motorised valves.

GET a different book cause you have messed up somewhere
all the neutrals are together. but theres loads of em pushed together in the tame wiring center terminal. il ave a look at tommorow. thought it might be that. wired to honeywell wiring guide. never let me down before so i reckon one of the neutrals isnt making contact. cheers.

Makesure no strands of wire hanging out and touching easily don e
A 'neutral' not making contact creates a 'open circuit'.
If a 'neutral' is making contact with a 'live' which it shouldn't be then that is a 'short circuit'

one of those so called neutrals may be an unflagged live ie a return from
a stat, or some other switching device
