What to do if my Daikin Boiler shows offset adaptation at limit?
If your Daikin Boiler's offset adaptation is at the limit, reset the boiler and perform a manual calibration. Increase the C5 parameter value. If the problem repeats, replace the PCB.
What to do if my Daikin Boiler has a DHW temperature sensor fault?
If your Daikin Boiler indicates a DHW temperature sensor fault, it will continue to supply domestic hot water. However, for accurate DHW temperature, check the DHW NTC sensor and its electrical connections for interruptions, and replace any defective parts.
What to do if my Daikin Boiler has an internal PCB error?
If your Daikin Boiler displays an internal PCB error, perform a reset. If the error occurs frequently, replace the PCB.
What to do if my Daikin D2CND024A1AA Boiler has an outside sensor fault?
If your Daikin Boiler shows an outside sensor fault, check the outdoor NTC sensor resistance using a multimeter connected across the thermistor’s terminal pins, and replace it if defective. Also, check the cable connections of the sensor, replacing them if defective.
What to do if my Daikin Boiler has a gas valve current error?
If your Daikin Boiler displays a gas valve current error, interrupt the power. Check the electrical leads of the gas valve and the gas valve itself. Replace any defective parts.
What to do if my Daikin Boiler has low system pressure?
If your Daikin Boiler displays a low system pressure error, fill the system up to 0.8 bar. The boiler will automatically start running once the pressure goes above this level, so a reset is not needed.
What to do if my Daikin D2CND024A1AA has freeze protection?
If your Daikin Boiler is in freeze protection mode, it means the flow temperature sensor is reading a value less than 1°C. The appliance will not operate until the flow temperature exceeds 1°C. Ensure that you do not cut off the electrical supply to the boiler.
How to fix Daikin Boiler parameter CRC error?
To address a parameter CRC error in your Daikin Boiler, first, reset the boiler. Then, perform a manual calibration. If the problem persists, consider replacing the PCB.
What to do if my Daikin D2CND024A1AA has a flow temperature steep rise?
If your Daikin Boiler experiences a steep rise in flow temperature: * Fully open the isolating valves. * Open the radiator valves. * Check if the pump is operating and inspect the electrical connections to the pump. Replace any defective components.
What to do if my Daikin D2CND024A1AA Boiler displays a water pressure sensor fault?
If your Daikin Boiler is showing a water pressure sensor fault, check the pressure sensor and its cable connection for any interruptions. Replace any defective parts.
