Figure 12. Freezer Control Panel
The control panel is located on the top right side of your freezer. You can use the
three pushbuttons (#5, #8, and #9 in Figure 12) to change the temperature
display (#1) or to adjust temperature and alarm setpoints as given in Section 9.3.
The thermometer display (#2) provides a quick visual indicator of current
cabinet temperature and alarm conditions.
1. Main temperature display - during normal operation, shows cabinet
temperature in degrees Celsius, as measured by the primary sensor inside
the cabinet. You can use the buttons to display other values such as
setpoints, highest and lowest recorded temperatures. The number in the
main display flashes when the value can be modified.
2. Thermometer - shows cabinet temperature and alarm conditions. There
are 10 horizontal bars: 9 are displayed during normal operation, the
tenth (top) bar indicates a warm alarm condition. The number of bars
illuminated indicates approximate cabinet temperature. With the
default settings, 4 to 6 bars illuminated indicate that the cabinet is at
desired setpoint. For example, suppose that the cabinet temperature
setpoint is -20°C and that the warm and cold alarm setpoints are -25°C
and -10°C. Then the number of bars illuminated indicates cabinet
temperature as follows:
