    Very flexible

    We automated 4 boilers with this controller. Very easy to install and simple to configure. The color touch screen is refreshing and the system was connected to the control network. Engineers created a a graphic screen and now the control room has full access. Extremely cost effective and quality is great!

    Easy to operate and great flexibility

    The NexSys controller allowed us to connect using BACNet and the control room has full access to the water treatment controller. Color touch screen facilitates calibrations and operation in the field. Great product!
