UDT - Universal Defrost Timer
Universal Defrost Timer (UDT)
The Universal Defrost Timer family consists of two models: electric defrost and off-cycle defrost. Both models can
be wired directly to 120V AC, 208V AC or 240V AC power sources. The timers can be used in place of traditional
electromechanical defrost time clocks. Users should review this document, including terminal specifications, to ensure
compatibility with the application.
The timer maintains and displays the current time and each defrost cycle. The user can glance at the display and
immediately determine what time it is as well as see the defrost settings (start time and duration). In
addition, colored LEDs indicate the current system mode (refrigeration or defrost).
