The Tracer™ ZN525 is a configurable HVAC controller designed and optimized for controlling Chilled Water Terminal units equipped with EC fan motor technology. ZN525 offers a truly compact solution with an embedded 230Vac power supply. ZN525 is LonMark certified and supports SCC 8501 profile.
Trane Tracer™ ZN525 can control chilled water terminal units such as fan coil units, chilled beams or cassettes, in different configurations (2 pipes, 4 pipes, with or without electric heaters, etc).
The combination of Tracer™ ZN525 and EC fan motor technology ensures optimum energy efficiency through:
• Fan speed optimization resulting in lower fan motor operating costs
• Noiseless operation with smooth fan speed adjustment
• Reduced power up inrush current through Random Start function
• Demand limiting of electric heaters, avoiding peak time rate periods
Tracer™ ZN525 is proposed as a factory mounted controller on the entire Trane Chilled Water Terminal rangeequipped with EC motor technology. The ZN525 drastically reduces on-site commissioning time, and ensures optimum quality and reliability of the assembly. Tracer™ ZN525 is also proposed as a field installed controller. DIN rail or screw mounting, and removable terminal strips allow Tracer™ ZN525 quick installation. A quick configuration tool is also available for easy installation.
The Tracer™ ZN525 integrates a specific control algorithm, based on room and discharge air temperature measures, as to eliminate uncomfortable 'hot/cold shower’ feelings.
Tracer ™ ZN525 can deliver a fully integrated room comfort solution when associated with Trane lighting and sun blinds controllers, Tracer™ EXL and Tracer™ EXB. Tracer™ ZN525 is fully compatible with the existing Trane wall interfaces range, ZSM10, ZSM11 and ZSM31, including wireless ZSM31-W.
