Cure
Check the circulating pump and heating system
Vent the system
Check the correct parameter setting
Disconnect the power supply to the boiler for 60
seconds and then reinstate the boiler
Do the Calibration procedure [AUTO SETUP].
Reset the fault and do the Calibration procedure
[AUTO SETUP].
If necessary, replace the gas valve or PCB.
Check that the fume ducts and the condensate trap
are not blocked. Check the correct gas supply
pressure.
Do the CO adjustment in TEST mode. If neces-
2
sary, do the Calibration procedure [AUTO SETUP].
Check that the fume ducts and the condensate trap
are not blocked. Check the correct gas supply
pressure.
Do the CO adjustment in TEST mode. If neces-
2
sary, do the Calibration procedure [AUTO SETUP].
Check the connection
Turn the power off and on
Turn the power off and on
Reset the fault and do the Calibration procedure
[AUTO SETUP].
Initially solve the problem, reset the fault and check
correct ignition.
Do the Calibration procedure [AUTO SETUP].
Replace the board if necessary.
Reset the fault and check for correct ignition. Do
the Calibration procedure [AUTO SETUP]. If the
problem persists, replace the board.
Check the gas supply, fume ducts and condensate
drain. Check the correct position and state of the
electrode After about 3 minutes the error is reset.
Check if there are pressure peaks in the DHW cir-
cuit. If necessary, modify parameter b11.
Check the correct position and condition of the
electrode.
Check the PCB.
Check the gas valve and replace it if necessary.
