Using the hybrid extension kit for Vitodens 200/300

In this video, we show you the steps required to prepare an existing OneBase Vitodens 200/300 with the hybrid expansion kit for CAN communication with a Vitocal heat pump. Suitable for types B2HE, B2HF, B3HF, and B3HG, manufactured from April 2019 to March 2025. The Vitodens 200/300 types B2HH and B3HH are already CAN bus hybrid-compatible , and do not need to be retrofitted. If you want to retrofit, you will need to replace the control unit with the hybrid expansion set.
