When entering the room. the guest have to insert the room card. same card for the door. into the energy conservation switch. to tum on the illumination system, when leaving the room, the guest draw the room card, then the power supply will be shut off by the Energy Conservation switch in about 15 seconds.
The delay function is very important in the Energy Conservation system; without it. guest would have to leave the room in the dark. The consumption of the illumination in each room in a hotel is about 2000 watts. if the guest forgets to the electrical appliances when they leave the room. it will be a great waste and it's very insecure. So we specially developed the Energy Conservation switch for hotels. and offices to save the substantive regrettable consumption.
