SERIES-TSX3 DIGITAL TEMPERATURE SWITCH

The Dwyer Series TSX3 is a digital refrigeration temperature switch designed for the complete control of compressors, fans, and defrost cycles. It is frequently used in commercial refrigerators and chillers where HACCP compliance is required.

SERIES-TSX3 DIGITAL TEMPERATURE SWITCH for Compressor Control & HACCP Logging, Energy-Efficient

The Series TSX3 Digital Refrigeration Temperature Switch was designed to control the compressor, fan, and defrost in refrigeration applications. This generation of controls has field selectable engineering units and temperature probe types in order to reduce the combination of parts that need to be stocked. A built-in real time clock is used for HACCP logging of temperature alarms caused by temperatures out of their set limits or loss of power. The Intelligent Defrost parameters manage the defrost cycle in order to save energy cost. The digital input can be used to remotely trigger a defrost cycle, monitor cooler door status, or act as an external alarm. For programming multiple units, the model TS2-K configuration key can be used to quickly download parameter settings.

KEY FEATURES

  • HACCP Logging: Built-in real-time clock logs temperature alarms caused by limit exceedance or power loss.
  • Intelligent Defrost: Manages cycles based on time or manual triggers to optimize energy efficiency.
  • Flexible Programming: Features a 3-digit LED display and is compatible with the TS2-K configuration key for rapid multi-unit setup.
