Taco zone valves are an essential part of a heating system. They control the flow of hot water through the pipes in your home. Having a proper wiring diagram is essential to getting your system up and running properly. In this article, we’ll provide you with a detailed guide to understanding and wiring Taco zone valves.

Components of a Taco Zone Valve

Before we get into the details of wiring, it’s important to understand the basic components of a Taco zone valve. The most common type of Taco zone valve is the “Taco 571” series, which is a two-wire, one-piece valve. It has a body, motor, thermostat, and a two-wire connection. The body houses the motor and thermostat and the two-wire connection allows it to be connected to the system’s power source.

Installing the Valve

Once you’ve identified the components of a Taco zone valve, the next step is to install it. The first step is to turn off the power to the system. Then, you’ll need to identify the correct piping. Depending on the size of the valve, you may need to use a combination of copper and plastic piping. After you’ve identified the piping, you’ll need to connect the valve to the piping. This is done by attaching the valve body to the piping with a union nut. Once the valve is in place, you can re-energize the system.

Wiring the Valve

Once the valve is installed, you’ll need to wire it. The most important thing to remember when wiring a Taco zone valve is that it must be wired in series with the other components of the system. To do this, you’ll need to identify the two wires coming from the valve and connect them to the appropriate terminals of the system’s power source. It’s also important to note that the wiring must be done using the correct wire gauge for the system. Too small of a wire gauge can lead to system failure.

Testing the Valve

Once the valve is wired, it’s time to test it. To do this, you’ll need to turn the thermostat up to a high temperature and then turn the power off to the system. After the system has cooled completely, turn the power back on and then turn the thermostat down to its original setting. If the valve is working properly, it should turn on and off accordingly. If it doesn’t, you may need to adjust the wiring or replace the valve.

A Taco Zone Valve Wiring Diagram

A Taco zone valve wiring diagram is a great way to understand the wiring of the valve. It will show you how the two wires from the valve should be connected to the system’s power source. It will also show you how the thermostat should be wired to the valve. A wiring diagram can be found in the product’s instruction manual or online.

Troubleshooting the Valve

If you’re having trouble with your Taco zone valve, there are a few steps you can take to troubleshoot the issue. First, check the wiring to make sure it’s connected properly. If the wiring is correct, check the thermostat to make sure it’s working properly. The last step is to check the valve itself. If the valve is malfunctioning, it may need to be replaced.


Installing and wiring Taco zone valves is an important part of setting up a heating system. Understanding the components of the valve and how it works is the first step in getting your system up and running. With the right wiring diagram and a few simple steps, you can easily install and wire a Taco zone valve. Once it’s installed and wired properly, you can rest assured that your system will be running smoothly.
