Boiler fuse tripping after installation

Hi all,

Eventually got everything set up with my new V3+, boiler ran for an hour fine and eventually got the app working. Then the boiler tripped, changed the fuse and ran for about and hour again. I'll try and add pictures of my wiring, something must be wrong.

These are the before and after pictures of the controller and thermostat, then the capped off thermostat and new tado receiver.

Thanks 🙏
