Cure
Check correct positioning and opera-
tion of the flow sensor and replace it if
necessary
Check the circulating pump and hea-
ting system
Vent 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 fume
probe
See fault A07
Check the electrical system
Check the electrical system
Check if parameter b04 is configured
correctly (default 0=pressure switch)
System pressure value outside set
limits (transducer)
Fill the system
Check the water pressure switch
Check the wiring or replace the sensor
Reconnect the external probe or disa-
ble the sliding temperature
Check and if necessary modify para-
meter b15 to 3
Check the circulating pump and hea-
ting system
Vent the system
Check the correct parameter setting
Disconnect the power supply to the
boiler for 60 seconds and then reins-
tate the boiler
Do complete manual calibration
Reset the fault and do complete
manual calibration.
If necessary, replace the gas valve or
PCB.
