I found the manual and wiring diagrams online, brother-in-law fitted the boiler (he's a plumber) but is worried about wiring the thermostat in case he pops a fuse...
Seems pretty straight forward to me 2 wires to connection 3&4 only problem being which way round??doesn't seem to tell you in the boiler install manual.
Below is the bumph and attached are the wiring diagrams, any help would be greatly appreciated.
The boiler terminals 3, 4 and 5 are for connecting external
electrical controls such as a time switch and/or room
thermostat. Terminals 3 and 4 are linked together when
the boiler is supplied. If external controls are used, this
link must be removed, and the controls connected
across terminals 3 and 4. Terminal 5 is an additional
neutral connection for external neutrals such as from
the anticipator of a room thermostat.[/img]
