What it is
The Viessmann Vitotronic 100 HC1B is a boiler control unit from the Viessmann Vitotronic control range, identified by part number 7452256. It forms the control interface for the appliance it is fitted to, handling the boiler's operating sequence and settings. It is supplied as a standalone control unit, not as part of a kit.
Before you order
- Confirm the part number 7452256 against the existing control unit or the appliance's technical documentation.
- Check that the model designation on the existing unit reads Vitotronic 100 HC1B, as other Vitotronic variants are not interchangeable.
- Have the appliance model and serial number to hand if you need to verify compatibility before ordering.
- Retain the existing unit until the new one is fitted, so any wiring references remain available.
