Temperature Probe Calibration
The R280 Frozen Food Dispenser uses a single
temperature probe mounted to an insulated spacer on
the top wall of the cabinet compartment in the upper
right. It is the temperature displayed on the control panel
and is used to control the refrigeration system.
The temperature control is factory set. Unless the
controller or the temperature probe are replaced, it will
not be necessary to change these values. In addition,
raising or lowering the set point temperature can
compensate for small discrepancies between the probe
temperature and actual temperature. However,
differences greater than 2º should be corrected. The
method for adjusting the temperature probe is simple, but
requires an accurate thermometer (preferably certified)
to measure the probe’s deviation from the actual
temperature.
Place the thermometer into the freezer compartment as
close to the cabinet temperature probe as practical. The
machine should be operating at or near normal operating
temperature, -2°F to 10°F (-19°C to -12°C). If the
thermometer has a sensing probe, make certain that it is
not touching any metal in the compartment. Otherwise it
may give a false reading.
Wait 5 minutes with the Dispenser operating normally
and the door closed.
Check the thermometer reading and compare it with the
temperature displayed on the operator panel. The best
time to check is just after the compressor shuts off.
If the difference between the display and the
thermometer is greater than 2º, an adjustment should be
made.
Note:
Calibration of the temperature probe is performed
from the Diagnostic functions menu using the operator
panel on the front of the Dispenser, and may require a
manager's password to access the menu.
