Abstract
A multi-mode control device is provided for controlling a load device. A high-power interface of the control device can be electrically coupled to a high-power module. An occupancy sensor can receive a first current from the high-power module via the high-power interface, and a trigger detection device can receive a second current that is less than the first current from a low-power module via a low-power interface. The processor can switch the control device from a high-power mode for powering the occupancy sensor to a low-power mode by causing a reduction in the current provided to the occupancy sensor and causing current to be provided to the trigger detection device. The trigger detection device can detect a trigger in the low-power mode. The processor can cause the control device to operate in the high-power mode based on the trigger's detection.
