| Unit has been higher than 25°F above the maximum cavity |
|
| Over temperature | more than 2 minutes. Note: Holding Cabinets with this error code are |
| |
|
|
| more than 145°F higher than the maximum |

| Temp. measurement error | Contact factory. |
| |
| Temp. measurement error | Contact factory. |
| |
| Real time clock error | Data set to factory default. Ensure that date and time are correct if applicable. |
| |
| Real time clock error | Contact factory. |
| |
| Voltage low | Voltage below 90 VAC on a 125 VAC unit, or below 190 VAC on a |

| |
| EEPROM Error | Ensure that all temperatures and times are properly set. |
| |
|
|
| Contact factory if problem persists. |
|
| EEPROM Error | Contact factory. |
| |
| EEPROM Error | Contact factory. |
| |
| EEPROM Error | Contact factory. |
| |
| EEPROM Error | All timers, if previously on, are now off. Possible bad EEPROM. |
| |
| EEPROM Error | Stored HACCP memory corrupted. HACCP Address reset to 1. Possible bad |
| |
|
|
| EEPROM. Contact factory if problem persists. |
|
| EEPROM Error | Stored offsets corrupted. Offsets reset to 0. Control may need a recalibration. |
| |
|
|
| Possible bad EEPROM. Contact factory if problem persists. |
|
| EEPROM Error | All timer |
| |
|
|
| off. Possible bad EEPROM. |
|
| Button stuck | A button has been held down for >60 seconds. Adjust control. Error will |
| |
|
|
| reset when the problem has been resolved. |
|
| Datakey error | Datakey digital signature incompatible. Cycle power, and install compatible |
| |
|
|
| Datakey if error persists. |
|
| Datakey error | Datakey incompatible with control. Install compatible Datakey. |
| |
| Datakey unplugged | Install Datakey and cycle power to control to clear error. |
|
Note: If in doubt, always cycle the power to the control and contact factory if the problem persists.
To test probe and air sensor:
Test probe and air sensor by placing sensor in ice water bath and using an ohmmeter set on the ohm scale. The reading should be 100 ohms resistance. If it is more than 2 ohms higher or lower, sensor needs to be replaced.
