Temperature Alarm ON/OFF (Temperature Alarm)
There is an audio/visual temperature alarm that can be enabled to warn a customer if excessive warm or cold tem-
peratures are experienced. To enable the alarm, press and release the key with the bell on it (See Figure 3-8). If
the alarm is enabled, the BELL ON indicator will illuminate. To disable this feature, press and release the key with
the bell on it again, and the BELL ON indicator will de-energize.
NOTE: If the alarm is enabled and there is a temperature problem, the BELL ON indicator will flash and the alarm
will beep. The alarm feature can also be tied in with a home security alarm system.

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 Celsius or Degrees Fahrenheit Display)
The electronic control is initially set to display temperature in Celsius (°C) units of measure. Units of measure can
be converted from °C to °F (Fahrenheit), 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 Celsius (°C) to Fahrenheit (°F) readings, press and hold the ALARM
key and the POWER key simultaneously for five (5) seconds, then release the keys (See Figure 3-9). A temperature
is now shown in the left display window, and the right display window indicates the units of measure as °C or °F. In
this case, a temperature will be displayed in Celsius (°C) units of measure. (See Figure 3-10)
To switch from Fahrenheit to Celsius, 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 POWER key first, as that will simply switch the unit OFF.
