The Setpoint temperature is the
desired cabinet temperature set-
ting. When the Temp UP button
is pressed and held (and provided
that the unit is up to temperature),
the actual cabinet temperature
is displayed. When the button is
released, the Setpoint temperature is
displayed.
NOTICE: Models DCH-120/220/320
have an adjustable tempera-
ture range of 100-165° F (38-
74° C). Since the tempera-
ture can be set below 150°
F (65° C), which is below the
safe holding temperature for
some foods, only NON-MEAT
products should be held in
these units. Models DCH-
100/200/300 have an adjust-
able temperature range of
150-165° F (66-74° C).
1. Turn the unit ON. The display
will ash “LO” to indicate that the
unit is heating up. After 20-30
minutes (when the unit is up to
temperature), the display will
show the setpoint temperature.
2. To adjust the setpoint tempera-
ture, press and hold the Temp
Up and Temp Down buttons until
the display begins to ash. Re-
lease the buttons. Then, press
the Temp Up or Temp Down
buttons to raise or lower the
setpoint temperature. Release
when the display shows the
desired temperature.
3. To change the display from
Fahrenheit to Celsius and back,
press and hold the Temp Scale
button (Figure 3) for 2-3 seconds
and release.
4. Open the rear door(s) and place
the serving table pan(s) into the
unit (Figure 4). Load the pan(s)
with the food product using
tongs or a similar utensil. Close
the door(s).

continues to display this code until the unit reaches the
setpoint temperature. When the unit reaches the set-
point temperature, it displays the setpoint temperature.

This gure shows an example setpoint temperature of
200° F displayed on the console.
“HI” ashes if the actual cabinet temperature exceeds
the setpoint temperature or if the thermistor has shorted.
NOTICE: The thermistor should be 100k ohm +/- 2% at
room temperature.
“OPEN” ashes if the thermistor is OPEN or disconnect-
ed. The unit will not call for heat.
NOTICE: The thermistor should be 100k ohms +/- 2%
at room temperature.
“PO” In 120 VAC units, this code ashes if the sup-
ply voltage is below 100 VAC or above 135 VAC. In
220/240 VAC units, this code ashes if the supply volt-
age is below 190 VAC or above 265 VAC.
NOTICE: If voltage is within normal ranges, then the
Control Board is faulty.
To reset a unit in this state, the supply voltage must be
within acceptable limits and the unit must be turned o󰀨
for a few seconds and then turned back on.
