WARMERS - ELECTRONIC CONTROL OPERATION
ELECTRONIC CONTROL DISPLAY AND BUTTONS
The control has a 3 button interface.
• The “POWER/UP” button is used to turn off the warming
cabinet or for increasing values.
• The “SET/MUTE” button is used to lock in a new value or to
access the set point.
• The “DOWN” button is used for decreasing values.
The control icons shown above will be illuminated when the
associated function is active. When the “HEATER” icon is illumi-
nated, the heaters are ON. When the “FAN” icon is illuminated,
the fan is ON..
NOTE: The electronic control has 1 probe. This probe is
used for regulation of the warming cabinet temperature
and is located in the return air stream.
HOW TO TURN OFF/ON WARMING CABINET
The warming cabinet is shipped with the control in the “ON”
position. When in the “ON” position, the current cabinet tem-
perature will be displayed along with the icons that are active:
fan and/or heater icon.
When the warming cabinet is in the “OFF” position, the current
cabinet temperature will alternate with “OFF” in the display. The
heaters and the fan(s) will remain off.
1. To turn “OFF” the warming cabinet:
2. To turn “ON” the warming cabinet:
a. Press and HOLD the “POWER” button for 5 seconds.
b. Release the “POWER” button. The display will alternate
between “OFF” and the cabinet temperature.
a. Press and HOLD the “POWER” button for 5 seconds.
b. Release the “POWER” button. The display will show cur-
rent cabinet temperature, the fan icon will illuminate and the
heater icon will illuminate if the cabinet is below the cut-in
temperature.
HOW TO CHANGE THE SET-POINT
Warmers are factory set to maintain an average temperature of
180°F. The set-point is the temperature that the warming cabinet
heaters will shut off. There is a negative 8 degree differential. So
if the set-point is 184°F, the warmer cabinet heaters will turn off
at 184°F and turn back on at 176°F.
To change set-point:
1. Press and HOLD the “SET” button until the current set-point
begins flashing. Release the “SET” button.
2. Press the “UP” or “DOWN” button to adjust to the new set-
point value.
3. Press and release the “SET” button to lock in the new set-
point. The control will now resume normal operation with
the new set-point.
HOW TO CALIBRATE THE ELECTRONIC CONTROL
The controller temperature display can be calibrated if required.
Before attempting to calibrate the temperature display, check the
display by placing a pre-calibrated temperature sensing device
in the center of the warmer compartment and keep the doors
closed for at least 15 minutes. The temperature display should
read the same temperature as the sensing device, within +/-3°F.
If not, follow these instructions to calibrate.
1. Press and HOLD the “SET” button until “PS” appears flash-
ing in the display. Release the “SET” button.
2. Press the “UP” button until “/C1” appears in the display.
Release the “UP” button.
3. Press and release the “SET” button. The current value of the
offset will appear in the display.
4. Press the “UP” button to increase or the “DOWN” button to
decrease the offset value.
5. Press and HOLD the “SET” button for 5 seconds to confirm
and save the new value. When complete, the current tem-
perature will be displayed. RELEASE the “SET” button.
EXAMPLE: If a sensing device in the cabinet reads 170°F and
the control display shows 175°F, follow the steps above and
decrease the current offset by 5°F. If the current offset is 0,
change to -5. The display will now read 170°F.
