The Actuator (com.prosyst.mbs.services.da.items.Actuator) device item represents an actuator that controls the given value. All valid values lie within the range. To present the type of the value you should use the generic parameter Q which extends Quantity<Q>. In contrast to the Setpoint, the Actuator sets the value immediately. For example, it can set the value of the open- loop system like a dimmer.
