Paragon DJ2000-00 Defrost Timer 4-Hour 20-Min

The Paragon DJ2000-00 Defrost Timer regulates predetermined defrost cycles in HVAC systems coordinating when refrigeration equipment pauses cooling for ice removal during refrigeration operation. Its timing mechanism initiates the defrost sequence after a four-hour operating interval and maintains that cycle for 20 minutes. The time interval establishes the frequency of defrost initiation, while the 20-minute setting provides the duration needed for the programmed cycle to proceed. This timed operation supports consistent evaporator temperature and airflow conditions and keeps refrigeration equipment operating through controlled frost removal.
