What it is
The Biasi BI1801102 is a diverter valve actuator used on Biasi Rinnova Adaptive M300V series boilers. It drives the diverter valve to switch the appliance between central heating and domestic hot water operation. The actuator is supplied as a single component for replacement on the listed models.
Signs this part needs replacing
- Domestic hot water runs cold or fails to heat while the heating circuit still works
- Radiators heat up when a hot tap is opened, or hot water is produced when heating is called for
- DHW temperature fluctuates or the boiler cycles between heating and hot water modes
- The actuator head does not move or respond when the boiler switches modes
- Diverter valve related fault codes or lockout on the appliance display
Before you order
- Confirm your boiler model against the fitment list above, as the actuator is listed for the Rinnova Adaptive M300V.2025 SM, M300V.2530 SM and M300V.3035 SM only
- Check the part number on the existing actuator head matches BI1801102
- Establish whether the fault lies with the actuator head or the diverter valve body before ordering, as the two are separate components
- Inspect the wiring plug and actuator mounting for damage or corrosion before fitting
