Can I use a wireless room thermostat with Worcester 20-25?

We have a Worcester Bosch 20-25 oil combi boiler but we don't have a room thermostat, instead we have TRVs on all but one radiator. We find that even on the lowest setting the lounge gets too hot so we have to turn off the boiler when it gets to 20 degrees.

I have seen the wireless room thermostats such as the Honeywell 927 which would seem to be ideal but I'm unsure whether it would work with our boiler. I have looked in the manual and there is mention of fitting an external programmer but as I understand it a wireless thermostat such as the 927 offers the flexibility of a programmer as well.

There are details for fitting a room thermostat in the manual which has three connections: Neutral, Switched Live and Room Thermostat (Remove Link).

Can anyone confirm that the 927 will work with the WB 20-25 please?

Thanks in advance.
