The HOA switch, which stands for Hand-Off-Automatic switch, controls the operational mode of a device or system, such as lighting. When the switch is set to the AUTO position, it allows the system to operate automatically according to its predetermined settings or sensor inputs.

In the context of energizing lights, the AUTO setting means the lights will turn on and off based on the control system or sensor conditions, such as daylight or occupancy sensors. This is crucial for energy efficiency and suitable operation of lighting systems.

The other settings typically affect the lights differently. The MANUAL position would require a human operator to turn the lights on or off, whereas the OFF position completely disables the lights, preventing them from being energized regardless of any automatic conditions. The RESET position is generally used to return a system to a normal operating state after a fault or an interruption but does not specifically energize the lights. Therefore, AUTO is the correct setting to energize the lights as it enables them to function as designed based on the automatic controls.
