Prerequisites

Before you begin, ensure you have the following:

  • OpenTherm Gateway (for Vaillant boilers without OpenTherm built-in)
  • Screwdriver
  • Electrical tape

Step-by-Step Guide

1. Install the OpenTherm Gateway (if necessary)

If your Vaillant boiler does not have OpenTherm built-in, you will need to install an OpenTherm Gateway. Refer to the manufacturer’s instructions for specific installation steps.

2. Connect the Gateway to the Boiler

Use the provided cables to connect the OpenTherm Gateway to the boiler. Ensure the connections are secure.

3. Power the Gateway

Plug the OpenTherm Gateway into a power outlet and switch it on. The gateway should indicate a successful connection with a blinking light.

4. Connect the Nest Thermostat to the Gateway

Use an Ethernet cable to connect the Nest thermostat to the OpenTherm Gateway. Ensure the cable is properly plugged into both devices.

5. Power the Nest Thermostat

Insert the batteries into the Nest thermostat or connect it to the power supply. The thermostat will start up and display the setup screen.

6. Configure the Nest Thermostat

Follow the on-screen instructions to configure the Nest thermostat. Select “Heating” as the system type and choose “OpenTherm” as the thermostat type.

7. Test the Connection

Adjust the temperature on the Nest thermostat and observe the response of the Vaillant boiler. If the boiler responds correctly, the connection is successful.

If you encounter any issues during the connection process, refer to these troubleshooting tips:

  • Check all connections to ensure they are secure and properly made.
  • Reset the Nest thermostat and the OpenTherm Gateway by unplugging them and plugging them back in.
  • Ensure the OpenTherm Gateway is compatible with your Vaillant boiler model.
