Abstract
The room temperature control unit is provided with a switch for determining whether the room is vacant or occupied and if required with a switch for determining whether the room is cooled or heated, so that the room temperature is controlled while the room is vacant to be somewhat (e.g. 2.degree. C.) higher than a set temperature when the room is cooled, and somewhat (e.g. 2.degree. C.) lower than a set temperature when the room is heated. For that purpose, at least two common contacts are provided and they are connected to switch contacts in different ways so that one common contact is selected according to whether the room is vacant or occupied.
