How to connect wireless thermostat to boiler

I’ve bought a wireless thermostat and opened the box, but now I’m staring at the boiler wondering where it actually wires into. How do I connect this thing to the boiler?

"Hire a professional eg a qualified Gas Safe registered Engineer if boiler case has to be opened for wiring, a qualified Electrician can do the job otherwise. Thanks"
