E. Instructions for Setting and Calibrating Digital Display Thermometer:
Victory’s digital display thermometers have a sensing range of -40
°
F to 220
°
F (-40
°
C to 105
°
C) which allows it to be
used in a wide variety of applications.
Setting the control for proper application is accomplished by installing the jumper on the “HI” or “LO” pin position.
“HI” for Refrigerators and Freezers, and “LO” for Warming Cabinets.
1. Calibrating the Display Temperature
The alarm switch must be placed in the right (T) position when calibrating the temperature as shown above.
*Note: The digital thermometer has a built-in delay and displays a temperature change every two (2) minutes.
This prevents the display from showing erratic temperature readings during door openings. When
making any calibration adjustments, allow two minutes for the delay to register temperature
changes.
a. Using a reliable dial or digital thermometer, place the sensing device in the center area of the cabinet.
b. Turn the temperature calibration screw clockwise to increase the temperature, or counter-clockwise to
decrease the temperature. Wait two minutes for the display to respond to the new settings.
2. Setting the Alarm
a. Move the alarm switch to the left (AL) position.
b. Turn the alarm adjusting screw clockwise to increase the setting or counter-clockwise to decrease the
setting.
c. Set the temperature to the appropriate range for the application as shown above.
d. Move the alarm switch to the right (T) position.
*Note: The alarm is indicated by a flashing display temperature and occurs when temperatures rise above
the alarm setting for refrigerators and freezers, or when temperatures drop below the alarm setting for
warmers.
Changing the jumper to read in “Centigrade” will not require further calibration or alarm adjustment.
