Honeywell T3R wireless thermostat

I have just had this installed and the fitter left me with the Quick Start guide. There is a link on there to get the full instruction manual from the Honeywell website and every language imaginable is there - but the English one won't load. I tried a few other languages and they all work! Does anyone have a link to this please that does work?
On the receiver unit can anyone tell me the function of the button with a flame symbol? I'm assuming that this is to override the thermostat signal in order to run the heating but then at what temperature will the boiler switch off (or won't it until the button is pressed again)?

That works a treat - many thanks. Any idea about the 'flame' button on the receiver? I mean, will it simply run the heating until the boiler reaches its own internal water temperature irrespective of how the thermostat is set - it's not very clear on the documentation.

your room thermostat will send a signal to the boiler to keep providing heat, until the room that the thermosta is situated reaches the temp that you have set it at, then it will tell the boiler to shut down, the boiler has its own internal thermostat that senses the temp of the water in the system and that will tell the boiler when to modulate or shut, down depending on the temp of the system water not the room, all boilers are different but work similarily
