Vaillant VR71 Wiring Centre 5 Relay enables the VRC700 to control up to a three zone system when paired with the VR70, which ultimately enhances the system functionality. This is the ideal addition for your new boiler purchase because it uses conventional commercial lines for the wiring and the controller controls and regulates the operations via an eBUS interface.
