To Next PageTo Next PageWhy is my Aerco BMK 1500 showing a WARNING 02 LEVEL HIGH?
A high O2 level warning in your Aerco Boiler can be caused by a Gas Pressure Regulator or Air Blower problem, bad Combustion Calibration, an O Offset that is too high, or a bad sensor. You may need to increase the O Offset value, or replace the sensor.
What to do if Aerco BMK 1500 shows O2 SENSOR OOR MAINT REQUIRED (OutOfRange)?
If your Aerco Boiler displays an O2 SENSOR OOR MAINT REQUIRED (OutOfRange) error, it could be due to the sensor auto calibration offset required being more than ±3%, a bad sensor, or a bad ECU. Try to reset the unit and recalibrate the sensor or replace the sensor; replacing the ECU is also an option, but it is rare.
What causes the O2 SENSOR MALFUNCTION in Aerco BMK 1500?
If your Aerco Boiler is showing an O2 SENSOR MALFUNCTION, it could be due to a bad sensor or a communication issue. Try checking the wires and connections or replacing the sensor.
How to fix a low O2 percentage in my Aerco BMK 1500 Boiler?
An O2 percentage that is too low in your Aerco Boiler can be caused by a dirty filter, poor combustion calibration, an O Offset that is too low, or a bad sensor. To resolve this, recalibrate the unit, increase the 2 Offset value or replace the sensor.
How to troubleshoot BV Hi Err on Aerco BMK 1500?
A BV Hi Err in your Aerco Boiler indicates that the trim operation exceeds allowable blower voltage limits. To fix this, check the air filter, gas regulator, and combustion calibration.
What to do for a BV Lo Err on an Aerco BMK 1500?
If your Aerco Boiler is showing a BV Lo Err, check the sensor calibration; it may need to be replaced.
How do I resolve Max Iter on my Aerco Boiler?
If your Aerco Boiler displays Max Iter, check the sensor calibration for inaccuracies and increase gain or iteration attempts.
