NOTE: If in doubt, always cycle the power to the control and contact factory if the problem persists.
Possible Cause s
Cavity air sensor reading < 5°F (-15°C). Verify sensor integrity.
Cavity air sensor reading > 517°F (269°C). Verify sensor integrity.
Product probe reading < 5°F (-15°C). Verify sensor integrity.
Product Probe reading > 517°F (269°C). Verify sensor integrity.
Unit has been more than 25°F (14°C) below set point for longer than 90 minutes.
Unit has been more than 60°F (33°C) above the maximum set-point for longer than 3
minutes. Holding Cabinets with this error code are more than 145°F (81°C) above the
maximum set-point.

Refer to wiring diagram for the particular model and ensure dip switches on the
control match the settings called out on the WD. If the dip switch settings are correct
according to the print replace the control.
Voltage below 90 VAC on a 125 VAC unit, or below 190 VAC on a 208-240 VAC unit.
Correct voltage.
Voltage over 135 VAC on a 125 VAC unit, or over 250 VAC on a 208-240 VAC unit.
Correct voltage.
Ensure that all temperatures and times are properly set.
Contact factory if problem persists.

All timers, if previously on, are now off. Possible bad EEPROM.
Stored HACCP memory corrupted. HACCP Address reset to 1. Possible bad EEPROM.
Contact factory if problem persists.
Stored offsets corrupted. Offsets reset to 0. Control may need a recalibration.
Possible bad EEPROM. Contact factory if problem persists.
All timer set-points are reset to 1 minute. Timers, if previously on, are now off.
Possible bad EEPROM.
A button has been held down for > 60 seconds. Adjust control. Error will reset when
the problem has been resolved.
Contact factory.
Datakey digital signature incompatible. Cycle power, and install compatible Datakey
if error persists.
Datakey incompatible with control. Install compatible Datakey.
Install Datakey and cycle power to control to clear error.
Cycle power. Contact factory if error persists.
Plug in SD card and cycle power. Contact factory if error persists.
