Lennox Control Board Wiring Diagram

By | June 16, 2022



Understanding how to wire a Lennox control board is essential for anyone looking to install one. Although properly wiring the board is a complicated process, it doesn't have to be daunting if you have the right information and tools. To help you complete the task, here is a guide to wiring your Lennox control board using a Lennox control board wiring diagram.

The diagram shows all the necessary connections between the board, the external controls, and the system components. The first step is to turn off power from the main circuit breaker before making any connections. Then proceed to connect the board's terminals and wires to the appropriate components as indicated in the wiring diagram.

Once all of the necessary connections are made, it’s time to configure the board settings. This can be done within the board’s programming interface. Begin by setting the switch positions for the fan limit, filter reset, heating and cooling functions, and other features. As you configure the settings, make sure to refer back to the wiring diagram to ensure you’re making the correct connections.

Next, you’ll need to connect the board to your local network so that the board can receive signals from external controls. Some boards have built-in Wi-Fi capability, but in most cases, you’ll have to use a separate router or bridge to make the connection.

Finally, it’s time to test the system. Make sure to test both the internal and external connections of the board. Also, run tests on the board’s operation and settings to ensure that everything is working as it should. If any problems arise, refer back to the wiring diagram for assistance.

Wiring a Lennox control board can be a complex process, but with the help of a wiring diagram and a few basic instructions, you can get the job done. With the right knowledge and the right tools, you can complete this task quickly and safely.
