Before you start

Before you begin, make sure:

You have the K 40 RF gateway
The heat pump is physically installed and powered on
The K 40 RF gateway is updated to the latest software version

Step-by-Step Instructions

1. Connect the heat pump to the network

Connect an Ethernet cable to the LAN port on the K 40 RF gateway
Verify the connection is established by checking the LED on the gateway

For network infrastructure requirements and troubleshooting, see Infrastructure requirements for the gateway.

2. Discover the heat pump in the commissioning wizard

The heat pump is now ready for the commissioning wizard. The gateway will scan the network to find available devices, which may take a few minutes. Once complete, the heat pump will appear on the results page.

Indicate whether the heat pump's electricity is billed on a dedicated heatpump tariff or as part of household consumption. Heat pumps on a dedicated tariff are excluded from self-sufficiency optimization.

3. Connect the heat pump to the gateway

After the scan completes and the heat pump is discovered, click Next in the commissioning wizard to proceed to the EEBUS connection screen.

On this screen, click Pair to initiate the EEBUS pairing process
Accept the pairing on the heat pump
1. Access the service menu
2. Navigate to
  System settings → Manual commissioning → Search EEBUS devices
3. Select the gateway and confirm the device details
4. Wait for coupling to finish and verify the connection

FAQ

Why isn't the heat pump appearing in the commissioning wizard?

Check that the K 40 RF gateway is connected via Ethernet and that EEBUS commissioning is complete. Verify that you've selected the gateway during the EEBUS device scan. Restart the gateway and wait for the network scan to complete.

How do I update the firmware of the heat pump?

You can perform the update through the Bosch EasyService App.
For detailed update instructions, refer to the official Bosch documentation.

How do I access the service menu?

Hold the menu icon (three horizontal lines) for the displayed number of seconds to open the service view.

What is the K 40 RF gateway and where does it connect?

The K 40 RF gateway is a communication module for Bosch heat pumps. It connects to the RF interface on the heat pump and provides an Ethernet port for network connectivity. The module is required to connect a Bosch heat pump to the gateway.

What EEBUS settings are required on the heat pump?

After completing the EEBUS pairing, navigate to System settings → EEBUS → PV own consumption optimization and enable the setting. This allows the energy management system to control the heat pump. For optimal performance, also configure the temperature settings described in the Recommended settings section.

How do I verify the EEBUS connection is active?

After pairing, navigate to System settings → EEBUS on the heat pump. The connected gateway should appear as a paired device in the device list. If the gateway is not listed, repeat the pairing process in the commissioning wizard.
