ABSTRACT:
To save energy in hotel and motel rooms, apartments and temporarily occupied rooms generally, an apparatus for saving energy includes a temperature control circuit that overrides a thermostat for controlling an air conditioning unit in a hotel room and a switching circuit to disconnect power to lights when the room is not being occupied. The temperature control circuit maintains the temperature of the room at a higher temperature to save energy, but not so high as to return the temperature of the room to a comfortable temperature. To return power to lights and control of the air conditioning unit to the thermostat, a tag attached to a key necessary for entering the room must be inserted into a switch included with the apparatus. A delay circuit permits the person sufficient time to leave the room after removing the tag before the thermostat is overridden and power to the lights disconnected.
