Boiler not firing

I have replaced an old BG UP1 and RS1 with a wireless V3+ set up. I am pretty sure that I have wired everything in correctly (hopefully anyway) and the app recognises that the system is trying to heat the house and turn water heating on.
Can anyone suggest what might be getting in the way? The RS1 was a wireless thermostat and has been replaced with the wireless Tado thermostat so I'm wondering if it is something to do with the wireless receiver next to my hot water tank, but haven't a clue what to do with it...

    Thank you for this! After configuring the system it all seems to be working fine now.
