2 Port ValveSystem WiringOperation - Hot WaterOperation - HeatingOperation - Hot Water and Central HeatingPossible ProblemsThe valve has two plumbing connections - in and out. With no power applied, a spring holds the valve closed so no water will flowtrically, the valve has 5 wires: 1. Green/Yellow, Earth - connected to the metal body of the valve. 2. Blue, Neutral - internally connected to the neutral side of the motor. 3. Brown, Live in - Activates the motor inside the valve 4. Grey - Connected to one side of a switch inside the valve. 5.

Simplified S-Plan and Y-Plan Wiring diagrams
Discuss Simplified S-Plan and Y it is all part of the same circuit, it just shows a lack of understanding of the actual circuit and a 'wire by numbers' approach. Jamchiv01-Nov 27, 2016 Thread Starter Thread Starter #10 I know it's not a borrowed neutral, the title says "Simplified". I am trying to draw as little on the diagram so it's

Circuit Diagram - Learn Everything About Circuit Diagrams
A circuit diagram is a visual display of an electrical circuit using either basic images of parts or industry standard symbols. Symbol usage depends on the audience viewing the diagram. These two different types of circuit diagrams are called pictorial (using basic images) or schematic style (using industry standard symbols).
Central Heating Design
The hot water and central heating design for the W Plan is different to that of the S Plan and S Plan Plus. The W Plan uses a three port motorized valve instead of the two port valve(s) used in the above plans; C, S and S Plus. The three port valve that is used in the W Plan is a 'two' position diverter valve.
