Boiler override if roomstat fails?

How can I run the boiler for heating if the roomstat fails?
Is the some sort of override function on the boiler?
I have a Worcester Greenstar 25 Si combi controlled by a Danfoss RET B & RX1 RF receiver

I was not expecting sarcasm fro this site. The manual has no reference to the problem. I was hoping for some help.

Why not simply find the manuaks and read them?
