The additional technology controllers allow several process variables to be simultaneously
controlled using one converter.
Example
An HVAC system with heating and cooling valves to process the air:
● The main controller controls the speed of the fan drive.
● The additional technology controllers control the cooling and heating via the two analog
outputs.
