Description
The Vaillant VRA42 Power Adapter Board is for use with the Vaillant myVaillant Connect VR940F internet gateway, and allows this to be powered by the eBUS heat generator instead of using a power supply plug.
Please Note: The Vaillant VRA42 is only compatible with the current range of Vaillant ecoTEC Plus boilers, for older boiler models you will need to use a power supply plug with the Vaillant myVaillant Connect VR940F.
