Actuate Thermal Components

Set Thermal components to target positions for one minute or sweep them twice between end points. The routine will complete when all components have reached their target positions. Until then, other components will remain at their target positions or continue sweeping. Unselected components will default to a target position that minimizes noise, vibration, and harshness (NVH).
