What You'll Need
Electrical tape

Wire nuts
Long nose pliers
Wire strippers or cutters

In a cooling or heating system, a zone valve constitutes a specific types of valve that controls the flow of heat or water. For the benefit of the occupants and the room into which the cooling or heating systems are installed, these systems are further divided into several zones. This allows you to direct the heat or cool to a particular room or place where the heating or cooling is desired, and it reduces the amount of air traveling to other rooms that no one is occupying. Read on to learn how to wire a zone valve to achieve this effect.

Step 1: Disconnect the Power

Before you start wiring the system, you need to exercise safety measures. Shut off the power of your irrigation controller to avoid short circuiting your cooling / heating system. When not careful, you might touch both irrigation wires and end up blowing your fuse. If this happens, it might cause a fire or permanent damage to your unit.

Step 2: Split the Wires

Split both of the two wires of the zone valve you are about to use. The distance where you should split these two wires must be an inch from the solenoid of the zone valve. When splitting the wires, you can make use of you wire stripper or cutter. This is better than using a sharp blade like a knife to cut wires. The hazard of not using a wire cutter is that you might end up cutting yourself or you might end up consuming the entire length of the wire because of the lack of control when splitting wires with a sharp object.

Step 3: Twist the Common Wires

Make use of your long nose pliers for twisting the common wire (white) from the valve’s solenoid. When doing this, you must be able to form some tight splices. Also, when doing the wire twisting, you can choose any of the wires from the valve’s solenoid. It would not matter what wire you choose for anything will work for this step. After choosing and twisting a wire, you should twist the nut you have made to the splice until it fits firmly. Finally, you should fill the nut of the wire with your silicone.

Step 4: Twist

Use long nose pliers to twist your other wire into the last wire until they firmly fit. Then, twist it to the other splice, similar to what you did in the last step. Now fill the nut of the wire with your silicone.

Step 5: Wrap the Valve Base

Finally, use your electrical tape to wrap both the slices that you have made. For best results, it is recommended that you connect the taped splice to the valve base.
