Why Defrost Control?

UL873 Vs. UL917
Relay Information
Manufacturer Comparison
Q&A
 Both mechanical and electronic controls are rated
to UL873 commercial refrigeration standards ie.
30,000 cycles
 Controls allow for a more precise termination of
the defrost cycle based on temperature or
pressure value
 Manufactured products for the refrigeration
industry since 1905
 Controls are often called defrost timers because
most popular method of defrosting equipment is
based on a time schedule
 Easy to install and program especially in retrofit
applications
Commercial Refrigeration Applications
 Refrigeration equipment
 Reach-In Coolers or Walk-In Freezers
 Prevents unwanted build-up of frost or ice
 Shuts off the compressor electric or alters its function
(hot gas defrost)
 Helps maintain the refrigeration equipment’s ability to
remove heat from the controlled space
Defrost Control
Pressure Control
Temperature Control




Ice is a great insulator
Reduce costly inventory spoilage
Frost build-up on evaporator coil makes it less efficient
Defrost control will determine when to stop cooling to allow
the frost/ice build-up to thaw
 Decision is based either on
 Time schedule (defrost timer)
 Precise reading of the temperature or pressure (defrost controller)

Universal Defrost Timers (UDT)
Works with multiple voltages
Removes built up of ice and frost
Easy to install
Simple to program
Part 9145-00 temp terminated
Part 9045-00 time terminated
Available as mechanism only without case
 Add M to end of part number
 9145-00M
 Both mechanical and electronic controls are rated to UL873
commercial refrigeration standards
 Controls allow for a more precise termination of the defrost
cycle based on a temperature or pressure value
 Manufactured products for the refrigeration industry since 1905
 Controls are often called defrost timers because most popular
method of defrosting equipment is based on a time schedule
 Easy to install and program even in retrofit applications
The Paragon electronic defrost control matches traditional mechanical defrost
controls and adds a number of advantages
 Multi-Voltage control is smart voltage
 Designed to fit into existing enclosures
 Certified to UL873 Standards
 Built-in power loss protection
 No pins or trippers to lose
 Manual defrost option
 LED status indication
 Real time clock
 Backlit display
 Easy Installation
 Certified to UL873
 Switches rated at 30,000
cycles
 Last 16 years longer at 4
defrosts per day
 Initiate 15 minute manual
defrost
 Lighted display
 100 hours of power loss
protection
 Simple Programming
 Designed to fit Paragon®
enclosures
 Withstands most rigorous
applications
 Wires to 120V AC, 208V AC
or 230V AC
 Display has defrost time and
duration
 System status indicators
 Real-time clock
Why are these features important?
Feature
Benefit
Multi-Voltage
The universal voltage (120/208-240 VAC) requires no switch
selection or different terminals
Fits into existing
enclosures
There is no need to bend or replace conduit or run new wire.
Replacement can be as easy as wire up, wire down on the same
terminals
Certified UL873
Designed specifically for use with refrigeration equipment and to
refrigeration standards. Tested at 30,000 cycles vs. 6,000
Built in power-loss
protection
There are no batteries to buy or replace. All program and time
settings are maintained for a minimum of 100 hours
Why are these features important?
Feature
Benefit
No pins or trippers to
lose
LCD Display gives indication of defrost start and stop time without
pins that might slip or fall off
Manual defrost
15 minute manual defrost is perfect for between cycles or system
maintenance
LED status
Green LED for Defrost and Red for Refrigerate
Real-time clock
Intuitive clock display that reads clockwise and indicates time of
day with a flashing cursor
Backlit display
No need for torches or flashlights in dark mechanical rooms
 UL873 sets specific functional and life cycle standards for
equipment used in temperature regulation (refrigeration)
 UL873 insures the equipment will maintain safe and proper
operation in commercial refrigeration environments
 Competitive products (timers) use a different standard
 UL917 is for clock-operated switches
 Paragon universal defrost products are the only multi-voltage
defrost controls rated to UL873 standards

No load required
 Paragon® controls rated to UL873 are made to last five times longer
than timers rated to UL917 standards
Paragon Universal Defrost Timers are the only defrost timers
engineered to refrigeration standards.
