Model DHB-KFC

Prince Castle Food Holding Bins provide the capacity re­quired for large foodservice operations while performing at
peak energy efficiency. Each unit features two individually
controlled holding chambers. The DHB-KFC has shatter­proof lighting to illuminate foods. New Reli-A-Temp™
infrared heater technology holds product temperatures
more consistent within the designated holding time than
other types of heating systems. This exclusive heater
design spreads the heat evenly over the entire food holding
area, eliminating edge drop off. Food is kept at the desired
serving temperature.

OPERATION

1. Turn on power switch and light switch located
under control panel

2. Allow 20 minutes for heaters to reach set point
temperatures. For a cold start, the temperature
display will show LLL until the heater tempera­ture reaches 38°C.

Show the Setpoint Temperature for a heater:

1. Press the Up or Down Arrow button until the
heater number and front or rear heater indicator is
selected.

NOTE: To set to °F (The unit leaves the factory set in

Celsius) turn the power switch to the “OFF” position.
Press and hold the “UP ARROW” Button then turn
the power switch to the on position, release the “UP
ARROW” 10 seconds after turning on the power. To
switch from °F to °C turn power switch to the “OFF”
position. Press and hold the “DOWN ARROW”
Button then turn the power switch to the on position,
release the “DOWN ARROW” 10 seconds after
turning on the power

CALIBRATION

Occasionally, there are measured differences between the
restaurant’s temperature meter and what the controller
senses for a heater surface temperature. Part of the
difference is the location of the controller sensor versus
the location where the temperature was measured with
the restaurant’s temperature meter. The calibration mode
is used to adjust the Prince Castle controller to the
restaurant’s meter.

RESET TO FACTORY SETTINGS

To reset all times and temperatures to the fac­tory settings, turn unit off, press and hold the UP
and DOWN ARROW BUTTONS at the same time,
turn unit back on. A “P” will appear in the
display and all times and temperatures will be
reset to the original factory settings.

IMPORTANT: Allow heaters 20 minutes to stabilize before

starting the calibration mode.

1. Press the Up or Down Arrow button until the heater
number and front or rear heater indicator for the heater
to be calibrated are selected.

2. Make an external temperature measurement within
the shelf cavity near the center of the heater surface
using a stand alone temperature meter and probe (not
supplied).

CAUTION: Surface temperatures are HOT!
Use caution when making any temperature
measurements within the heater cavity.

3. Press and hold the PRI in the Prince Castle Logo and
the Actual Temp button for 3 seconds.The decimal

point to the left of the °C symbol will light indicating

the Calibration Mode. The temperature value displayed
on the front panel is the actual heater temperature
sensed by the controller.

4. To clear the calibrated offset value, press the Set
Point button. The display will show the temperature
value the sensing probe is measuring. Use steps 5
through 7 to calibrate the temperature display to the
restaurant’s standalone meter.

CLEANING

CAUTION: This appliance is not water
tight. Do not clean with a Water Jet/Jet
Spray. Do not immerse appliance in
water.

CAUTION: Before unplugging power
cord, make sure power switch is in OFF
position.

1. Unplug Holding Bin from outlet.

2. Allow unit to cool down. (Approximately 15
minutes.)

3. Wipe down with a damp cloth. Do not use a
green scotch bright pad, unapproved cleaner, ice

or water.

Calibration Mode Active

5. Use the Up and Down Arrow button to increase or
decrease the displayed temperature until it matches
the value measured by the standalone meter.

6. When the temperature value displayed on the front
panel is equivalent to the temperature value measured
by the standalone meter, press the hidden Prince
Castle Logo button.

7. The new value will be saved by the controller and
Calibration Mode will end.

TROUBLESHOOTING

The controller incorporates some diagnostic hardware and software to aid in troubleshooting problems. The
display will flash the problem if detected when the heater in question is selected. The error condition will not
display in the Change Set Temp mode.

IMPORTANT: To avoid a possible error message, do not program a differential greater than 30°F between

the front and rear of any heater assembly. The heater with the higher setting may not be able to get up to
temperature because heat will be flowing to the colder heater. An error message will be displayed and the
heater that could not get to temperature will be turned off.

Problem Cause Solution
