TS3-50020 - 

The Series TS3 Digital Temperature Switch is the ideal control for on/off heating or cooling 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 outside of their set limits or loss of power. For refrigeration applications, the defrost cycle can be initiated based on time or using the front panel keys. For programming multiple units, the model TS2-K configuration key can be used to quickly download parameter settings.
