ERROR CODE

When the boiler detects a fault, the alarm symbol is displayed on the
screen together with the relative error code and description.
CODE DESCRIPTION obtained from BMM
SAFETY THERMOSTAT
01
Safety thermostat intervention
BLOCK
04
No gas or burner ignition failure
NO FLAME DURING
05
OPERATION.
HIGH TEMPERATURE
06
Boiler temperature too high
10
INTERNAL FAULT
Flame detection before ignition (parasite
11
flame)
CENTRAL HEATING SENSOR
12
Central heating sensor fault
RETURN PROBE (if applicable)
14
Sensor (SRR)
INSUFFICIENT WATER CIRCULATION
15
Insufficient primary circuit water circulation
(∆t > 40° C)
HEAT EXCHANGER FREEZING ( 9 )
Heat exchanger freezing detection. If the cen-
16
tral heating sensor detects temperature below
2° C, burner ignition is prevented until the
sensor detects temperature above 5°C.
PARASITE FLAME
20
Flame detected after the burner is switched off
SPEED OUT OF CONTROL
24
Fan speed alteration; the speed is not reached.
It is possible to reset the boiler by pressing "A" from HSCP or RESET
from BCM
Press the release button on the panel and/or check if the thermostat and its connec-
tions are not disconnected. Make sure the INTC switches are closed (position 1)
Check gas supply or correct operation of the detection/ignition electrode(4-5).
Check detection electrode
Check pump operation and, if necessary, clean the heat exchanger (9 )
Check efficiency of the sensor (see Res/Temp table) (Par. 4) or its connections.
Check the wiring; if necessary, replace the sensor (15)
Check pump operation and its speed - remove any obstructions in the central
heating system
Disconnect electric power supply, close the gas cock, and carefully defrost the
heat exchanger.
Check the wiring and any leaks from the gas valve (2), replace the Gas valve if
necessary
Check operation of the fan (18) and the connections
