Better thermal regulator settings

Hi, I'd love to be able to set a target temperature range instead of a single value, that way I would not be constently wasting energy in unwanted temperature correction. An example:
For a regulator in an industry room I would set something like 5-25°C range: do not let overheat nor freeze. But as long as it is in range, stay idle.
Sometime you place them only to fight heat, sometime only to fight cold. And currently they are almost all the time running.
