Hargassner M-Bus Converter

Must be ordered in addition!

The 1.5 and 2.5 m³/h heat meters can be integrated into a Hargassner substation and of course connected directly to the Hargassner controller (M-Bus converter optional). All our heat meters from 1.5 to 15m³/h can be used with any Hargassner boiler.

The data is automatically transferred to the Hargassner controller by the additional “M-Bus converter” module and can therefore be read on the boiler display and on the web.
