Got a new boiler installed but our working tado with our previous boiler is not working
Hey all,
Today an installer finalized the installation of our new boiler, A Vaillant ecoTEC plus VCW 346/5-5 (E-BE) R6. At the end on the installation he asked us to try the tado thermostat but it wasn't giving any input to the boiler. So i showed him the installer manual for tado with vaillaint and then he connected the wires with EBus then in our wired thermostat he went into the installer menu and chose the setting following the installation guide, but with bad luck..i'm not sure if we are missing something, if so, i'd hope to get the solution from this forum.
I'll attach some images of the wire connections in the boiler and of the manual we followed
