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).
2
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

personal injury or loss of property, a separate safety control and/or alarm should be installed�
The schematic drawings and other information included in these instructions are for the purpose of
illustration and general reference only.
These instructions do not expand, reduce, modify or alter the Robertshaw Terms in any way. No warranty or
remedy in favor of the customer or any person arises out of these instructions.
The 9045 and 9145 controls have been certified by Underwriters Laboratories Inc. The certification does not
extend to their use for any other purpose. Robertshaw assumes no responsibility for any
unconventional application of its control unless such application has been approved in writing
by Robertshaw.
It is the responsibility of the installer and the user to assure that the application and use of Robertshaw products
are in compliance with all federal, state and local requirements, including, without limitation, all requirements
imposed under the National Electric Code and any applicable
building codes.
Mounting
Mount these controls to a wall or any flat surface using the three holes in the metal case (models
9045-00 and 9145-00). The control’s components are not position sensitive, but should be mounted so they can be
easily wired and adjusted. The models that do not come in a metal case must be mounted inside an enclosure (Nema 1
type or better).
NOTE: The manufacturer recommends removal of the electronic controller prior to mounting the metal
case to a wall or any flat surface to facilitate installation and the installation of conduit fittings and conduit installation.
CAUTION
To prevent possible electric shock or equipment damage,
disconnect electrical power to the unit before and during
installation. DO NOT restore electrical power to the unit until the
control is properly installed and the cover is assembled. DO NOT
locate the control in an explosive atmosphere as a safety hazard
can result due to possible spark generation in the control. Controls
are not to be located in areas of significant moisture, dirt or dust,
or in a corrosive, explosive atmosphere. Using a control in such
environments may result in injury or damage to persons or property
(or both) and are likely to shorten the control life. DO NOT connect
the supply (as shown connected to terminal F in Figures 4 and 6)
directly to any other terminal. DO NOT remove jumpers between
terminals C and D on model 9145 or between terminals B, C and D
on model 9045.
Robertshaw assumes no responsibility for any such use�
MISE EN GARDE
Pour prévenir les chocs électriques ou les dommages aux
équipements, couper l’alimentation électrique de l’unité avant
et pendant l’installation. NE PAS ali-menter le thermostat avant
que la commande ne soit correctement installée et le couvercle
assemblé. NE PAS placer le thermostat dans une atmosphère explo-
sive car une étincelle dans le thermostat représente un danger. Les
thermostats ne doivent pas être placés dans des zones très humides,
poussiéreuses ou sales, ou dans une atmosphère corrosive et
explosive. Si le thermostat est utilisé dans de tels environnements,
des préjudices aux personnes ou des dommages aux biens (ou les
deux) peuvent survenir et sont susceptibles de raccourcir la durée
de vie du thermostat. NE PAS brancher l’électricité (comme branché
à la borne F dans les figures 4 et 6) directement à n’importe quelle
autre borne. NE PAS retirer les cavaliers entre les bornes C et D sur le
modèle 9145 ou entre les bornes B, C et D sur le modèle 9045.
Robertshaw n’assume aucune responsabilité pour de telles utilisations�

Programming
Upon initial power up the flashing segment should be at 12:00 pm (noon). Turning the ADJUST knob will
activate the programming cursor and momentarily turn off the time. If any of the other segments are on
(lit), they may be related to a previous program. The display backlight will turn on when the ADJUST knob is turned. The
backlight remains lighted for 10 seconds after the last activity.
Program Reset
Program reset deletes any existing program and returns the clock to 12:00 pm (noon).
1. Press and hold the following (4) buttons at the same time for 1 second: MANUAL DEFROST, SET TIME, DEFROST
START/STOP and CLEAR.
2. Lighted segments showing any program will turn off, and the time segment will show 12:00 pm (noon).
Set the Time
The flashing segment shows the actual time.
1. Rotate ADJUST knob until the correct time is shown. Each segment is 15 minutes.
2. Press the SET TIME button to set the time.
Program a Defrost Cycle
1. Refer to original equipment manufacturer’s operating instructions for recommended defrost schedule.
2. Rotate ADJUST to move the cursor to desired defrost start time.
3. Press DEFROST START/STOP once. This indicates a timed defrost start time.
4. Rotate ADJUST to move the cursor to the desired time terminated or backup termination time.
5. Press DEFROST START/STOP once. This shows the termination time.
All the segments between the start and stop times will be lit.
Number of defrost cycles user may set: 12
Defrost periods: minimum 15 minutes, maximum 105 minutes (each segment is 15 minutes) Each defrost
cycle can have its own independent period.
Minimum time between defrost cycles: 15 minutes
Clear
To remove a defrost cycle:
1. Rotate ADJUST to the start time.
2. Press CLEAR once.
3. Defrost cycle is deleted. (All the lit segments linked with the defrost cycle, turn off.)
To remove part of the defrost cycle:
1. Rotate ADJUST to a segment within a defrost cycle.
2. Press CLEAR once.
3. The segments from the cursor location to the termination time are deleted. (The lit segments will turn off.)
Manual Defrost
Press the MANUAL DEFROST button to begin a manual defrost at any time during a refrigeration cycle. A manual
defrost lasts 15 minutes.
If a programmed automatic defrost is scheduled to start during a manual defrost, the control will automatically switch
from the manual defrost mode to the automatic defrost mode. The automatic defrost will end normally (time or
temperature).
If a manual defrost is started so that the refrigeration ON time between the end of the manual defrost
and the start of the next scheduled defrost violates the Short Cycle ON time requirement (see below),
the manual defrost period will be lengthened to the start of the scheduled defrost. Manual defrosts
occurring after ascheduled defrost that violate the Short Cycle OFF time requirement will initiate the
manual defrost immediately.
11
Short Cycle Protection
The control will not schedule a compressor run (ON) time shorter than five minutes. The control will not schedule a
compressor OFF time shorter than thirty seconds except for loss of power situations.
The operator can stop or start the compressor at any time.
Program Carryover
Time will be retained for a minimum of 100 hours; program retention is indefinite.
During loss of power, the display will be blank, the indicating lights are off and the relay(s) is/are
de-energized. When power is restored (less than 100 hours), the time and program will pick up where
the program is as if there had been no loss of power.
NOTE: After 100 hours, if the clock is lost the time is set to noon, and the program resumes.
Troubleshooting
Problem Solution
Backlight is not on.
The display backlight will turn on when the ADJUST knob
is turned and will remain on for 10 seconds after the last
activity.
The display segments and backlight are not on.
1. Verify proper voltage is applied to the correct
terminals.
2. Perform PROGRAM RESET.
3. Replace timer.
All the display segments and LEDs are flashing.
The control has detected a catastrophic or
programming failure. If possible the UDT will return to
refrigerate.
1. Verify proper voltage is applied to the correct
terminals.
2. Verify wiring of the device.
3. Perform PROGRAM RESET.
4. If problem clears, reprogram the device.
5. If indication remains, replace the timer.
The display is flashing a
G during normal operation.
Indicates a shorted defrost termination switch on
Terminal G. The control will default to its timed
termination point.
1. Verify wiring of defrost termination switch.
2. Verify switch operation, and replace defrost
termination switch if necessary.
3. Once the defrost termination switch is operating
normally, the flashing G will reset automatically.
(This may take one defrost cycle to reset.)
