Help installing Tado to Worcester Greenstar 34 Cdi Classic combi with MT10RF thermostat

Hi, I have gone through the whole installation process following the steps with my tado thermostat. All I would like to do is replace my existing wireless MT10RF thermostat with the tado thermostat and use it as a central thermostat. I do not have the smart rad valves or extension kit. Is this possible to do? I'm struggling to understand and how the tado smart thermostat can communicate with my boiler.
