The Trane Tracer ZN525 for terminal units with electronically commutated (EC) motors and the Tracer ZN523 for conventional terminal units have received eu.bac certification for use with water terminal units with two pipes and two wires, or with two or four pipes. Both controllers successfully passed all eu.bac tests, recording performance results that rank among the highest in their category.
eu.bac launched the European Certification Scheme for Building Automation (eu.bacCert) in response to the European Energy Performance of Buildings Directive and different national regulations, which require proof of building energy efficiency. eu.bac certification assures the user of a high level of performance and energy efficiency as well as compliance with the European standard EN 15500 for electronic individual zone control equipment.
The Trane Tracer ZN525 can be used on all Trane chilled water terminal units equipped with EC fan motor technology to provide optimum energy efficiency, increase comfort and reduce terminal operating noise. The Tracer ZN523 provides intelligent fan speed control to terminal units using the conventional alternating current (AC) fan motor technology.
In addition, it can be used on active and passive chilled beam applications. Both controllers are certified as a LonMark Space Comfort Controller type SCC 8501 and are offered as a factory or field-installed controller.
