Electric load control system including remote override function

A control system for a load control device comprising:

• a housing;
• an occupancy sensor unit associated with said housing and adapted for sensing the presence of an object;
• a light sensor associated with said housing and adapted for detecting ambient light level;
• a first processor associated with said housing and adapted for operating at least one load in response to at least one of the sensing by the occupancy sensor unit and the detecting by the light sensor;
• and
• an override unit operatively connected to the first processor, said override unit configured to receive remote signals originating externally of the housing and comprising at least one of command information and data information, and to output at least one of the remote signals to the first processor,
• wherein the override unit includes a second processor configured to receive the remote signals via wired or wireless communication, and to output at least one of the remote signals to the first processor to control actuation of the at least one load,
• wherein the override unit further includes an ambient light sensor disposed remotely from the housing, and the second processor outputs a signal indicative of light :level detected by the ambient light sensor, and
• wherein the first processor is responsive to the at least one of the remote signals for operating the at least one load independent of the sensing by the occupancy sensor unit and the detecting by the light sensor.

• a remote control device located remotely with respect to the housing and the override unit and in communication with the override unit, wherein the override unit is configured to receive from the first processor information indicative of an operation of at least one of the occupancy sensor unit, the light sensor, and the at least one load, and the remote control device is configured for selectively sending the remote signals to the override unit, or selectively receiving output signals from the override unit indicative of the information received from the first processor, or selectively sending the remote signals to and receiving the output signals from the override unit;
• and
• a remote ambient light sensor connected to the remote control device and located remotely with respect to the override unit, the remote control device being configured to communicate with the control device to selectively control the actuation of the at least one load in accordance with output signals from the remote ambient light sensor,
• wherein the first processor is responsive to the at least one of the remote signals for operating the at least one load independent of the sensing by the occupancy sensor unit and the detecting by the light sensor.
