What are the wires on a 2-port valve?
A 2-port (or Zone valve) has a permanent 230v supply (usually on the grey wire) plus a Neutral and an Earth wire. There is then also a Motor Live wire (usually the brown) and a Switch Live wire (usually the orange).
How does a Honeywell 2-port valve work?
When the programmer and stat send a Live feed to the 2-port motorised brown wire, the motor drives the valve open to allow water to pass. When the valve is fully open, the end switch closes, allowing electrical current to pass from the grey wire to the orange wire and from there to the boiler Switched Live.
