* An asterisk will appear if a RFID carafe is placed on a warmer
element.
The 4-digit number located in the middle of the main, top front
and top rear warmers can be used as a reference during trouble-
shooting.
• 4-digit number steady:
Means the coil frequency is staying
tuned
to the nominal value of 125.0 khz.
• 4-digit number flashing: Means the coil frequency is at the
low end of tuning, which will result in intermittent or failure of
writing and reading of the RFID carafes.
Faucet Assembly
The tube that’s connected from the tank to the faucet is now stainless with an
insulation wrap around it to help insulate the tube from temperature loss. The
requirement for the oatmeal mixing is 185°F water and a flow dispense of 5
ounces within 15 seconds.
RFID Glass Carafe
The glass carafe has an attached collar and strap that contains the RFID
transponder. The transponder is located within the strap holder, which contains
the assigned date and time recorded from the initial start of a brew cycle. The
operational range for reading and writing from the RFID sensor is approximately
.3/4 inches.
The collar and strap with transponder can be replaced as a complete kit (Bunn
PN: 42930.1000) on the glass carafe. See instruction sheet 43520.0000.
RFID Thermal Carafe
The thermal carafe has an attached RFID transponder holder adhered to the
side wall of the stainless housing. The brewer RFID board automatically can
sense when a thermal carafe is set on the warmer and will use the “Thermal
Fresh Hours” menu which is set at a 2 hours. The display will read “Ready To
Brew Thermal Carafe”. Anytime a thermal carafe is sensed, the corresponding
warmer will not activate or turn on. The operation range is the same distance as
the glass carafe but the transponder is not replaceable on the thermal carafe. A
new carafe will need to be ordered if the transponder fails or housing releases
from the stainless carafe housing.
