Operation and Functions
The Paragon® Universal Defrost Timer series is designed to accept power supply voltages of 120V AC, 208V AC
or 240V AC directly connected to the power terminals. This is accomplished without the use of jumpers or
switches. It is designed to be as easy to use as similar electromechanical defrost time clocks.
• Dial style clock face
• Current time indicated by flashing segment
• Scheduled defrosts and defrost duration indicated by solid segments
• Simple programming using three buttons and a rotating dial
Features not found on traditional electromechanical defrost time clocks include:
• System status indicators – LED for refrigeration and defrost
• Manual defrost initiation with a single button press
• Terminal G (defrost termination wiring connection) diagnostics
Features / Benefits
Universal Voltage ��������������������������������������������� Directly connect to 120V AC, 208V AC or 240V AC power supply.
Electronic User Interface .................................... Easy-to-read time of day. Simple defrost cycle programming. No
complicated dials and hard-to-use pins.

System Status Indicators .................................... Green LED indicates refrigeration. Red LED indicates defrost.
Manual Defrost ................................................... User-initiated 15 minute manual defrost cycle.
Non-Volatile Memory ......................................... The programmed parameters will remain in the memory.
Capacitor Carryover for the Clock ...................... Maintains the correct time-of-day for a minimum of 100 hours.
Microprocessor-Based Electronics ..................... High reliability and repeatability.
