Statistics show that an "Occupied" hotel guest room is actually "Unoccupied" over 65% of the time. GEMLink Wireless Energy Management System is designed to take advantage of this time when the guest is out of the room by adjusting room temps to a management determined energy savings set point. GEM Link Wireless Energy Management System® reduces energy costs 35 to 45 percent with typical payback in under in under 12 months based on average kWh rates throughout the Caribbean. Primarily designed for hotels, the system is equally applicable for college classrooms, dorms, offices, and military lodging facilities.
The following sequence events describes how GemLink Wireless works:
Guest arrives at the room.
Guestroom door is opened. GEM Link™ Wireless Entry Door Switch transmits Door Open status to the Transceiver Module.
Guest enters the room and is detected by the PIR Sensor, which transmits detection of the guest to the Transceiver.
GEM Link™ Wireless releases HVAC (air conditioner/heater) unit to its own thermostat control.
After door is closed, and guest detection has occurred, GEM Link™ Wireless locks in “occupied” mode. No further detection of guest is required to continue HVAC operation. GEM Link™ Wireless has released HVAC unit and has no control of guestroom environment. The guest has complete control of room temperature while in the room with Entry and Patio doors closed.
Entry door is opened again. Guest closes Entry Door and the Door Switch Module transmits Closed Door status to the Transceiver.
If another person has entered, GEM Link™ Wireless will again lock in “occupied” mode after room door is closed, with no interruption of HVAC operation, provided guest detection reoccurs within five (5) minutes.
However, if all guests have left the room for at least five (5) minutes, GEM Link™ Wireless turns off HVAC unit thermostat and enters Level 1 Temperature Setback. GEM Link™ Wireless controls room temperature ONLY while guests are out.
GEM Link™ Wireless maintains room temperature at a comfortable, energy conserving, management-selected high or low set-point while guests are away from the room.
