The Schneider Electric TAC Xenta 401 (Part No. 007301012) is a freely programmable LonWorks controller designed for medium-complexity HVAC plant and zone control within TAC Vista building automation networks, bridging the capability gap between compact terminal controllers and large plant controllers.
Suitable for dual-zone AHU control, secondary pumping systems, and combined heating/cooling plant management where more I/O is needed than the Xenta 301 provides, but the complexity does not justify the Xenta 491. Commonly found in hotel HVAC plant rooms, hospital wing controllers, and university building mechanical rooms.
