At Pan Delta, we provide a complete selection of industrial and marine control panels and electronic modules for alarm, monitoring and control purposes. We can also design and build custom control panels to match your requirements/specifications. On top of providing control panel fabrication services, we also offer green energy products such as Solar Charge Controllers and Solar Powered Monitoring Panels.




 The ECR-802 Hotel Room Key Tag System helps conserve energy by switching off non-essential electrical devices (such as heating, air conditioning, lighting, radio and television) when the guest leaves the room. This ensures that only occupied rooms consume energy!



The ECR-802 system consists of the key tag holder unit and the control unit.




When the guests enters the room, he inserts the key tag into the key tag holder unit. The ECR-802 senses the presence of the key tag and turns on power to the room. When the guests leaves the room, he removes the key and the ECR-802 will turn off power to the room after a delay of 30 seconds.





  • Reduces energy bill (system pays for itself!)
  • Extend life of light bulbs
  • Provides guest with the ideal place to keep the room key
  • Safe to use (key tag holder unit operates on 12 VDC
  • Suitable for hotels using card or key tag type systems.
  • Aesthetically pleasing design (available in black and white)


Example Scenario

Assuming each hotel room has the following:

5 x Lamps (at 60 W) = 300 W
1 x Television (at 150 W) = 150 W
1 x Air Conditioning Unit (at 750 W) = 750 W

Total load = (300 + 150 + 750) W = 1200 W or 1.2kWh

Assume energy is priced at $0.20 per kWh, the hotel has a total of 300 rooms with an occupancy of 70% and that
70% of the guests leave the lights and appliances on when they are out of the room and that the potential number
of hours saved per room is 5 hours.

Potential energy saving (in kWh) = 300 rooms x 70% x 70% x 1.2 kWh x 5 hours x 365 days = 321930 kWh/year
Potential energy saving (in $) = 321930 kWh x $0.20/kWh = $64386/year
