Turn-on procedure for a load control system
A load regulation device is adapted to control an electrical load. The load regulation device may be in a low power state, a ready state, and/or an on state. The low power state is characterized by the electrical load being unenergized. The ready state is characterized by a load control device and/or the load regulation device using more power than the low power state and the electrical load being unenergized. The on state is characterized by the electrical load being energized. The load regulation device is configured to receive an indication of a user's presence when the load regulation device is in the low power state. The load regulation device is configured to change from the low power state to the ready state in response to receiving the indication. The load regulation device is configured to wait in the ready state for a change state instruction.
