    Hi Guys , just got myself a Nest Gen3 thermostat, but am a bit bewildered with these connections on my boiler.
    Its a Vaillant Eco Tec plus 837 with theVRC 470f controller. IMG_5242.jpg
    Any help would be appreciated , I am a electrician but not on boilers.

    Hi turbo, frustrating as it is, it is all to do with casings forming a safe seal when removed and replaced.

    If you have a vr70, why go for nest? They will fight each other :96:

    Plan should be to get a gas safe engineer in.
