    I have just been on the phone to Vaillant, with the question: Is there any reason why I can't run a VRC 470F wireless thermostat from a VR65 control centre connected to a Ecotec Plus 438 boiler.
    It turns out the VRC 470F is now superseded by the VRC 700F; and after some cogitation, thinks it might need a new VR70 control centre aswell.. but he didn't sound too sure.
    The control at the moment is a Vaillant VRT 360F, but this has been so troublesome (on third remote controller..) we were looking for something else, and liked the idea of the external temperature monitoring of the 470/700.
    The current VR65 control centre as I understand is a fairly basic single zone controller, with the eBus connection. Does anyone have any experience of fitting a newer thermostat to an older control centre like this? Are they very specific to each model?
    Obviously swapping out the eBus connection is a doddle compared to completely replacing a control centre; but I've never dealt with Vaillant controls before, so I would be very grateful if anyone has any thoughts..
    Thanks
    Phil

    Old post I know, but I am just about to upgrade my own system on the cheap, with an old stock VRC 470F and a VR65 added to my new EcoFit Pure 418 and three port. I have emailed Vaillant three times in the past week, asking them to confirm the 470F and 65 will work with my present system. Each time they have completely ignored my question, but have just said the VCR 700(F) and VR66 are the current units.

    I will find out, when the kit arrives and I begin hacking.

    Anyone know if the outdoor wireless temperature sensor includes the DCF77 time receiver, or not? If it does, do they manage to receive OK in the middle of the UK?
