The DTS Digital Temperature Switch is a low cost unit that performs the functions of more expensive controllers. The switch is designed for heating or cooling control. Twelve different parameters can be programmed via the push button front panel. The heating mode can be used to keep temperature above a user-defined set point or alert an operator of a low alarm condition. In contrast, the cooling mode can be used to ensure process temperature stays below the critical level or signal high alarm condition. View temperature, error and alarm messaging on the bright red, 3-digit LED display. Units accept PTC probe input (sold separately) and include fitting clips for panel mounting and instruction manual.
