I have bought a Evohome WiFi Connected Thermostat Pack (ATP921R3100) and the HR92 radiator valves.

Please can you help in getting BDR91 relay box connected to the boiler.

The actual connections of the boiler are as pictured:

the main cable has 5 cables (brown, blue, green yellow and two black)

the white cable in the picture has (blue, brown and grey) which I believe it is going to the thermostat

The boiler manual:

Many thanks
