UNIQUE ELECTRONIC CONTROL INPUT OPERATIONS
The following pages describe unique input operations that a customer typically would not perform every day. The
input operations described here are Temperature Unit Selection Mode, Sabbath Mode and Showroom Mode.
Temperature Units Selection (Selecting Fahrenheit or Celsius Display - UC-24C Only)
NOTE: For Temperature Unit Selection in the models UC-24R, UC-24RO and UC-24B, see next page.
The electronic control is initially set to display temperature in Fahrenheit (°F) units of measure. Units of measure
can be converted from °F to °C (Celsius), and/or back again. This operation is called Temperature Units Selection.
NOTE: Temperature Units Selection must be performed within the first (1) minute of switching the unit ON.
To convert units of measure in a model UC-24C, first press and hold the Freezer
WARMER key and the POWER
key (this actually initiates Temperature Log Recall Mode, which is covered fully, later in this section). (See Figure 3-
8) Then, press and hold the Freezer
WARMER and COLDER keys for fifteen (15) seconds and “ °C “ will appear on
the LCD indicating temperatures will now be displayed in Celsius units of measure. (See Figures 3-9) To convert
back to Fahrenheit units of measure, repeat the steps above.
NOTE: Temperature Units Selection Mode will end ten (10) seconds after the last key stroke.
