The control was unable to read a piece of information from its EEPROM memory. The control will stop
operation until all settings in the Adjust menu have been checked by the user or installer. To clear the error
message and alarm, set Access Level DIP Switch A to Factory (on position), then check all Adjust menu items.
BOILER OUTLET SENSOR SHORT CIRCUIT
The control is no longer able to read the boiler outlet sensor due to a short circuit. In this case, if the boiler
inlet sensor is present and operational, the control will operate using the boiler inlet sensor. Otherwise,
the control will not operate the burner.
Test the boiler outlet sensor and related wiring. The error message will clear once the error condition is
corrected and a button is pressed.
BOILER OUTLET SENSOR OPEN CIRCUIT
The control is no longer able to read the boiler outlet sensor due to an open circuit. In this case, if the boiler
inlet sensor is present and operational, the control will operate using the boiler inlet sensor. Otherwise,
the control will not operate the burner.
Test the boiler outlet sensor and related wiring. The error message will clear once the error condition is
corrected and a button is pressed.
BOILER INLET SENSOR SHORT CIRCUIT
The control is no longer able to read the boiler inlet sensor due to a short circuit. In this case, the control
will continue operation.
Test the boiler inlet sensor and related wiring. The error message will clear once the error condition is
corrected and a button is pressed.
BOILER INLET SENSOR OPEN CIRCUIT
The control is no longer able to read the boiler inlet sensor due to an open circuit. In this case, the control
will continue operation.
Test the boiler inlet sensor and related wiring. The error message will clear once the error condition is
corrected and a button is pressed.
BOILER SUPPLY SENSOR SHORT CIRCUIT
The control is no longer able to read the boiler supply sensor due to a short circuit. In this case, if the boiler
outlet sensor is operational, the control will operate based on the boiler outlet sensor.
If the boiler outlet sensor is not available and the boiler inlet sensor is present and operational, the control
will operate using the boiler inlet sensor. Otherwise, the control will not operate the burner.
Test the boiler supply sensor and related wiring. The error message will clear once the error condition is
corrected and a button is pressed.
BOILER SUPPLY SENSOR OPEN CIRCUIT
The control is no longer able to read the boiler supply sensor due to an open circuit. In this case, if the
boiler outlet sensor is operational, the control will operate based on the boiler outlet sensor. If the boiler
outlet sensor is not available and the boiler inlet sensor is present and operational, the control will operate
using the boiler inlet sensor. Otherwise, the control will not operate the burner.
Test the boiler supply sensor and related wiring. The error message will clear once the error condition is
corrected and a button is pressed.
OUTDOOR SENSOR SHORT CIRCUIT
The control is no longer able to read the outdoor sensor due to a short circuit. In this case the control
assumes an outdoor temperature of 32°F (0°C) and continues operation.
Test the outdoor sensor and related wiring. The error message will clear once the error condition is
corrected and a button is pressed.
