Abstract
For a facility, such as hotels, motels, or apartments, energy expenses especially for air conditioning, heating and room lighting are one of major concerns of the management. This invention is pertaining to how to save the electricity usage by effectively controlling room lighting sand temperatures, from the front office.
In a hotel/motel environment, when a office clerk checks out a guest from a room, the room is automatically put in vacant status and, of which unnecessary lights are turned off, temperature is adjusted to the preset vacant level, and the room indicator LED is off showing that the room is vacant. When a new guest is checked in, the process is just opposite, turning the room indicator LED on, all lights are enabled to turn on, and temperature is adjusted to the preset occupied level for the room. Since this invention uses the existing telephone lines to control the room devices automatically from the front office, no extra wiring from room to room are needed for the communication.
