When an auto mode is engaged, a set point is created. The set point is the desired value for the vehicle to maintain. The set point is initialized at the current value for that Mode.

Examples:

• If the vehicles current heading is 076, and the Auto heading is turned on, the set value for the heading will be 076.
• If the vehicle’s current depth is 35m, and auto depth is turned on, the set point for the depth will be 35m.

Exceptions, the set points for the auto pitch and auto roll are always set to zero when first turned on.
