The A/TUC2 Series is a customizable sensor which features an on-board microprocessor, large backlit LCD display, set point, override and local system status when using the Override Feedback option. A single or dual sensing technology is employed when ordering NTC thermistor?ÇÖs due to their increased sensor resolution. The Platinum, Nickel, and Silicon RTD?ÇÖs all use a dual sensing technology due to their much lower sensor resolution. The single sensor technology reduces the error between the displayed and measured temperature output sent to your building management system. All accuracy measurements should be measured from the sensor output terminals with the LCD display being used for reference purposes only due to the rounding of the display to the nearest 0.5??F. To eliminate errors between the temperature shown on the LCD display and the temperature output to your building management system, a single point temperature offset can be entered in the TUC2. These units are factory configured to your desired specifications to reduce onsite programming. Additional features can be modified using the integral keypad and menu system, providing you with greater flexibility to meet any additional requirements. Additional features include additional Set Point configurations, Backlit Display brightness and functionality, Set Point Lockout, Direct and Reverse Acting Output adjustments, temperature offset, test functions and more.
