Digital Refrigeration Temperature Switch

Intelligent Defrost, HACCP Alarm Logging

TEMPERATURE

The Series TSX3 Digital 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.
