Cure
Check the wiring or replace the sensor
Reconnect the external probe or disable the sli-
ding temperature
Check the correct positioning and operation of
the heating sensor
Check the correct positioning and operation of
the return sensor
Check the circulating pump
Vent the system
Check the correct positioning and operation of
the return and/or delivery sensor and/or replace it
Check the correct positioning and operation of
the return sensor
Check the circulating pump
Vent the system
Check the card parameters and modify if neces-
sary
Check the circulating pump
Vent the system
Check the correct parameter setting
Check parameters and carry out a 100% calibra-
tion
Check the position of the electrode, replace it if
necessary. After replacement, repeat the 100%
calibration
Check the tightness of the flue pipe and the seal
of gaskets
Reset the fault. Turn on the hot water faucet and
wait for the flame to stop flashing (about 2 minu-
tes)
Check the ground connection.
Check the electrode.
Repeat the 100% calibration procedure.
If necessary replace the control unit.
Check the power supply
If necessary replace the control unit
Check the gas supply pressure
Check the supply voltage
Check ignition electrode and ground
Turn off power supply for 10 seconds, reset the
fault and perform a 100% calibration (Sc15=1).
Load the parameters
Repeat the loading procedure within 5 minutes
from the boiler power supply and replace the
BCC Service key if necessary
Connect the controller to the valve
Check the wiring or replace the valve
Disconnect the power supply to the boiler for 60
seconds and then reinstate the boiler
Reload the firmware or replace the card
