UNIQUE WINE STORAGE INPUT OPERATIONS

The following pages illustrate unique input operations performed at the control panel, namely: Temperature Units
Selection Mode, Sabbath Mode and Showroom Mode.
Temperature Units Selection Mode (Selecting Degrees Fahrenheit or Degrees Celsius Display)
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 minute after switching the unit ON.
To convert temperature units of measure from Fahrenheit (°F) to Celsius (°C) readings, press and hold the alarm bell
key and the UNIT ON/OFF key simultaneously for five (5) seconds, then release the keys (See Figure 3-9). A tem-
perature is now shown in the left display window, and the right display window indicates the units of measure as °F
or °C. In this case, a temperature will be displayed in Celsius (°C) units of measure. (See Figure 3-10)
To switch from Celsius to Fahrenheit, repeat the steps above within 1 minute of switching the unit on.
NOTE: Temperature Units Selection Mode will end ten (10) seconds after the last key stroke.
NOTE: Do not press and hold the UNIT ON/OFF key first, that will simply switch the unit OFF.
