Vaillant VRA42 Power Adaptor Board

The Vaillant VR940F myVaillant Connect Internet Gateway is for installations where a compatible thermostat is already installed and the end user wishes to add an internet gateway for Wi-Fi connection. The Vaillant VR940F myVaillant Connect Internet Gateway acts as both internet gateway and control (ErP Class II) providing the homeowner with access to myVAILLANT app. It's simple to install and has reliable and secure communication with the Vaillant cloud-to-cloud server. This version (0010037346) comes with a CIM cable instead of a power supply. When used with the new ecoTEC plus, myVAILLANT connect can be installed with the supplied one cable solution known as CIM (Customer Interface Module). The benefit of the one cable solution means there are no requirements for external power or additional caballing. Power and communication are achieved by the one cable connecting in to the CIM port located underneath the ecoTEC plus. For all other boiler installation situations, you will need to either locate an external power source or utilise the new VRA42 adapter which allows for power and eBUS to be taken directly from the boiler PCB.
