Boiler not working?

My Worcester Greenstar 30CDI is not heating the boiler since I changed the batteries on the thermostat

I think you'll find the thermostat and it's receiver are separate from the boiler and will have their own manual.

You might need to re-pair the thermostat sender. Check the manual.
