Wiring a Valiant ecotec plus 630

Hello,

I have a new boiler system and I’m using the wireless extension kit v3. The electrical engineer is struggling to get Tado to work properly. The boiler is a Valiant ecotec plus 630. The engineer has wired the control valves for the heating and hot water into the extension kit as well as the bus terminal. I think this is wrong but they are adamant it is correct. Please could you have a look at these photos and advise?

    It’s never possible to mix BUS and S Plan etc in Tado.You’d need to stick with relay control.

    @wdevereux Remarkably neat plumbing in the pictures! There are three motorised valves, presumably CH1 CH2 HW and relay control?

    I'd suggest that you contact Tado support from the chat function on the main Tado web pages.
