peak energy efficiency. The unit features a controlled holding

chamber capable of holding 3 half size pans. The DHB-

KFC3GB 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.

Each heater has independently controlled front and

rear sections. All heater zones are independently

controlled to set point temperatures. The following

is the relationship between the heater zones and pan

location. All heater zones are preset at the factory

for 182° C

Heater 1 Front = Left Upper, Front Heat Zone

Heater 1 Rear = Left Upper, Rear Heat Zone

Heater 2 Front = Middle Upper, Front Heat Zone

Heater 2 Rear = Middle Upper, Rear Heat Zone

Heater 3 Front = Right Upper, Front Heat Zone

Heater 3 Rear = Right Upper, Rear Heat Zone

IMPORTANT: Do not program a differential greater

than 17°C between the front and rear heater.

In the OPERATION MODE Up and Down

Arrows are used for selecting a shelf

heater zone for display purposes. In

PROGRAM MODE increase/decrease

the set point value for the current

heater being programmed.

In the OPERATION MODE when

pressed, display will show the current

zone. In PROGRAM MODE when

pressed will end the program mode.

In the OPERATION MODE when

pressed, display will show the current

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.

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

changes

3. Press and hold 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 Calibra

tion Mode. The temperature value displayed on the

front panel is the actual heater temperature sensed by

the controller.

4. This will clear or reset any previous calibration value.

Press the Set Point button, The display will show the

temperature value the sensing probe is measuring.

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 17°C 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.
