My Hive thermostat does exactly that. Per radiator. With as many times as I like (so the kitchen comes up to 19c during the week from 7-8 in the morning and from 6-8 in the evening). Oh, and it turns off when the window opens, and back on when the window shuts. So my wife deciding she wants it cold doesn't cost us a fortune.
