Hello
I bought a Vaillant Ambisense Starter pack (three TRVs and control unit) for my EcotecPlus boiler. I've connected the boiler's BUS terminals and the R920 controller's BUS terminals and , set up the Vaillant VRC700 app. There's an internet connection but when I open up the app I get 'Installation not compatible - no compatible control could be identified '. I've done the re-start etc but am getting nowhere.
Any ideas? I used 2 of the 4 core heat resistant cable that was used by my previous Siemens RF controller, might that be the problem?
Thanks
