CODE

DESCRIPTION 

SOLUTIONS 

01

SAFETY THERMOSTAT

Intervention of the safety thermostat 

(10)

Press Reset and/or check that the thermostat or 

its connections are not interrupted.

04

BLOCK

No gas or failed burner ignition

Check the gas supply or that the ignition/detection 

electrode is working properly 

(4)

.

06

High Temperature

Boiler temperature too high

Check pump operation and if needed 

clean the exchanger 

(24)

08

Water Deficency

Insufficient water pressure and consequent 

intervention of the minimum water pressure 

- pressure switch 

( 13 )

.

Fill the heating circuit as described in chap. 3.8 and 

wait for the values to return within default limits.

If needed, check the electrical connections and 

replace the minimum water pressure switch.

09

Outer Sensor 

Check the wiring, if needed replace outer sensor

10

Internal failure

11

Parasite Flame 

Flame detected upon ignition 

Check the wiring of the Ign/Det. electrode and re

-

move any oxidation. Check for humidity between 

drain wire and ceramic, if necessary, replace the 

electrode, press the unblock key, if the anomaly 

persists, replace the electrode (4).

12

Heating Sensor (11) 

Heating sensor fault 

Check the efficiency of the sensor (see table Res/

Temp) (Par.4) or its connections.

13

Domestic Hot Water Sensor

Domestic hot water sensor fault 

 (1)

Check the efficiency of the sensor (see table Res/

Temp) (Par.4) or its connections..

14

Inlet temperature Sensor
(SRR)

  

Check the efficiency of the sensor

 / 

and replace it

15

Water circulation insufficent

Primary circuit water circulation insufficient 

(∆t > 35° C)

Check pump operation 

(12)

 and speed - remove 

any heating system obstructions - clean the scaled 

domestic hot water exchanger
