Hi
I have a Drayton Digitstat SCR currently wired to my combi (Potterton Heatmax)
The wiring is not the same as suggested in the Tado setup guide. Could anyone help please?

Thanks,
Stephen

    The photo above shows the current wiring behind the Drayton stat.
    Would I be correct to think I need to connect both blue wires to N on the tado, both brown wires to L, grey and black wires to CH COM & CH NO, then join the 2 earth cables?

    Thanks

    Before answering, I think you need to clarify your black? and grey? wires on the SCR terminals and the Tado wiring instructions.
