cod. 3541V691 - Rev. 00 - 04/2022
Cure
Check the circulating pump and heating
system
Vent the system
check the exchanger and system
Check correct positioning and operation
of the flow sensor and replace it if neces-
sary
Check the circulating pump and heating
system
Vent the system
Check the wiring or replace the sensor
Insert the connector
Check the wiring
Replace the gas valve
Check the wiring or replace the sensor
Check the wiring or replace the sensor
Check the wiring or replace the fume
probe
See fault A07
Check the exchanger
Check the fume probe
Check the flue material parameter
Check and if necessary modify parameter
b15 to 3
Partially drain the system to a pressure
(shown on the display) of 1÷1.5 bar.
Check the expansion tank
Check if the parameter b04 is correctly
configured
System pressure value outside set limits
(transducer)
Partially drain the system to a pressure
(shown on the display) of 1÷1.5 bar
Charge or replace the expansion vessel
