Remedy
"Check the correct position and operation of the delivery sensor and replace
it, if necessary"
"Check the circulator and heating system"
Bleed the system
Check the wiring or replace the sensor
Check the wiring or replace the sensor
check the wiring or replace the valve
Check the wiring or replace the sensor
Check the wiring or replace the fumes probe
See fault A07
Check the electrical system
Check the electrical system
"Check if parameter b04 is configure correctly"
System pressure value outside the set limits (transducer)
Load the system
Check the pressure transducer
Check the wiring or replace the sensor
Reconnect the external probe or disable the sliding temperature"
"Check and change parameter b15 to 3, if necessary"
"Check the circulator and heating system"
Bleed the system
Check the correct parameter setting
"Disconnect the power supply to the boiler for 60 seconds and then, reset the
boiler"
"Run the calibration procedure [AUTO SETUP]."
"Reset the fault and run the calibration procedure [AUTO SETUP]". Replace
the gas valve or the electronic board, if necessary."
