Hello,
Wondered if anyone could help me? Firstly wondered if these come naturally open or closed or do you just turn them around? I would like to use zone valves to switch over from one feed pipe to another. Was going to use a thermostat to send power to them so wondered which wire fires up the motor and closes/opens the valve? Presume the blue is neg and yellow/green earth.
Sorry if I am a bit vague I am a HETAS engineer and most of my stuff comes pre wired.
Cheers. Colin.
