A06
No flame after the ignition phase
Ionization electrode fault Check the position of the ionization electrode, free
it from any encrustations and do the Calibration
procedure [AUTO SETUP]. Replace the electrode
if necessary.
Flame unstable Check the burner
air/fume ducts obstructed
Remove the obstruction from the flue, fume extrac-
tion ducts, air inlet and terminals
Trap blocked Check the trap and clean it if necessary
Wrong calibration Do the Calibration procedure [AUTO SETUP].
Insufficient gas supply pressure Check the gas supply pressure
F15 - A07
High fume temperature
The fume probe detects an
excessive temperature
Check the exchanger
Check the flue gas probe
Check the flue material parameter
A08
Overtemperature protection
intervention
Sensor not correctly positioned
on flow pipe or damaged Check the correct positioning and operation of the
heating sensor and replace it if necessary
No water circulation in the system Check the circulating pump
Air in the system Vent the system
A09
Exchanger protection interven-
tion
No water circulation in the system Check the circulating pump and heating system
Poor circulation and anomalous
flow probe temperature increase
Vent the system
blocked exchanger check the exchanger and system
F09
Overtemperature protection
intervention
Flow sensor damaged
Check correct positioning and operation of the flow
sensor and replace it if necessary
No water circulation in the system Check the circulating pump and heating system
Air in the system Vent the system

A23-A24-A26-F20
F21-F40-F47-F51
Pressure sensor fault
Wrongly configured parameter Check if the parameter
b04
is correctly configured
System pressure problems
(transducer)
System pressure value outside set limits (transdu-
cer)
b06
set to 3
F37
Incorrect system water pressure
Pressure too low Fill the system
Water pressure switch damaged
or disconnected
Check the water pressure switch
F39
External probe fault
Probe damaged or wiring shorted Check the wiring or replace the sensor
Probe disconnected after activa-
ting the sliding temperature Reconnect the external probe or disable the sliding
temperature
F19
Card parameter fault Wrong card parameter setting Check and if necessary modify parameter b15 to 3
