What is with people getting the wiring to this terminal wrong.

Went to a Vokera Minute HE coupled to a UV cylinder. Tidy pipework and tidier cable runs with good use of cable clips, cable glands and what nots.

Boiler leaking from the hosepipe. Dropped the pressure to zero to stop the leak after control on facia turned to OFF position. While am there, the pump starts running with boiler selector in OFF POSITION.

Bet the auxillary switch is getting its feed elsewhere to fire the boiler when boiler is switched off. Incidently, fitting a spur to isolate the boiler would be pointless as boiler would still be live from elsewhere sourced power feed to 3/4 termination
