The microprocessor based Series TSX offers a low cost solution for cooling applications. Units are designed to accept up to two temperature probes selectable between PTC or NTC thermistor input. The probe temperature is displayed on the bright 3-digit LED. The Series TSX offers 23 programming paramters for specific application requirements (see parameter chart on "Specfications" page). To quickly program multiple units with the seame settings, use the configuration key TS2-K (sold separately). The user can define set point, hysteresis, probe error performance, and defrosting. The defrosting mode can also be initiated or interrupted manually by pressing the up arrow button. Units include password protection to secure from unwanted setting changes except for set point adjustment. If required, the keypad can be locked out so no adjustments can be made.

Select from single units with one 16A SPST relay or dual output with on 16A SPST relay and one 8A SPDT relay for defrosting. The temperature switch includes one NTC probe, gasket, mounting clips, and instruction manual.
