Does anyone have a spare VR65 wiring centre?

After first confirming with Tado that my new Vaillant system boiler would be compatible with digital eBus and then having it installed, it transpired that actually it wasn't! "sorry for the inconvenience" was the reply from Tado!! Yes, their support and documentation is really really lacking knowledge and detail.

Anyway, after reading the threads I learn that I need a VR65 wiring centre to be able to control my S plan zone valves using eBus and this was confirmed by Tado also.

So the question is where do I find one? Does anyone have a spare unit?

If I cant find one then I will ditch Tado for good and switch to Vaillant vSmart.
