I've noticed that my Vailant boiler has both an PCB edge connector X31, used to connect to a VR33 module, and also a molex connector marked "BUS"
Am I right in thinking the VR33 interfaces to the eBus on the boiler - if so is the X31 connector a copy of the molex connection, with the addition of 2 power lines?
