ABSTRACT:
An individual room energy control system for selectively disconnecting and connecting electrical load means associated with a room to and from an electrical power source where the system includes a room status switch having room occupied and unoccupied positions located at a room status station for disconnecting the load means with the power means and a manually operated service switch in the individual room which may override the status switch when it is in a room unoccupied position whereby the load may be reconnected to the power source. The service switch may be incorporated in a telephone which in turn is included in a room status circuit to indicate when a room is unoccupied whereby a maid on entering a room for service may connect the load to the power source while she is in the room by operating the telephone.
