Hi, i am replacing a 2 port z5 drayton valve with a 3 port mid position drayton. Can anyone please tell me what changes i have to make to the wiring. Another post suggested: 'you have to connect both white and grey wires to where the brown wire of the old head was connected'

I have cocked up the wiring and now the heating stays on.

Have you actually replaced the valve head and body, or did you you change the actuator (powerhead)?
