Claim of US Patent No. 10,462,882

1. A control device for controlling power delivered to an electrical load, the control device comprising:a receiver configured to receive signals from occupancy sensors, the signals comprising an occupied signal indicating an occupancy condition and a vacant signal indicating a vacancy condition, the vacant signal transmitted based on the occupancy condition not being detected by the respective occupancy sensor;
a memory; and
a controller configured to control the power delivered to the electrical load in response to the signals received via the receiver based on a determination of which one of the occupied signal and the vacant signal is received, the controller configured to store in the memory for a respective occupancy sensor an occupied indication when the controller receives the occupied signal from the respective sensor, and store in the memory for a respective occupancy sensor a vacant indication when the controller receives the vacant signal from the respective sensor;
wherein the controller is configured not to cease the delivery of power to the electrical load based on a vacant signal received from one of the occupancy sensors when the memory indicates the occupied indication for at least one other occupancy sensor, the controller further configured to cease the delivery of power to the electrical load based on a vacant signal received from one of the occupancy sensors when the memory indicates the vacant indication for all other occupancy sensors.
