Stands for residual heat. Basically once your engine has reached operating temperature you can only then use the function.
It is for things like when you drop the kids off at school or nip into the shops for 10 - 15 mins and when you trun everything off press the rest button and it keeps the heating going to keep your car warm / cold for you whist you have gone for 10 mins or so.

Great little function on a cold / warm day.
