BOILER PROTECTION DEVICES

Boiler protection devices

The boiler is protected from malfunctioning by means of internal

checks performed by the electronic microprocessor P.C.B., which

stops the boiler from operating if necessary.

In the event of the boiler being shut off in this manner, a code

appears on the display which refers to the type of shut-off and

the reason behind it.

There are two types of shut-off:

Safety shut-off

This type of error is “volatile”, which means

that the boiler starts up again automati-

cally as soon as the problem which caused

the shut-off is removed; the error is indicat-

ed by the «

» symbol which appears

on the display and the error code.

In fact, soon as the cause of the shut-off

disappears, the boiler starts up again and

continues to operate normally.

In the event of error 108 - Shut-off due to insufcient water

pressure inside the heating circuit - the boiler will perform a

safety shut-off.

You can increase the pressure by lling the

heating circuit.

In this case or if the re-balancing request is

performed on a frequent basis, switch the

boiler off, turn the external electric switch to

the OFF position, shut off the gas cock and

contact a qualied technician to check for

any leaks of water.

Shutdown

This type of error is “non-volatile”, which means that it is not

removed automatically. To restore normal operation press the

button on the control panel.

Important

If this shutdown occurs frequently, contact an authorised

Technical Service Centre for assistance. For safety reasons, the

boiler will permit a maximum of 5 resets in 15 minutes (5 presses

of the RESET button); at the 6th attempt within this 15-minute

period the boiler will shut down and may only be operated

again after the electricity supply has been disconnected. If

the shutdown is occasional or an isolated event, this is not a

problem.

Malfunction warning

This warning is shown by the display in the following format:

5 P1 = FIRST IGNITION ATTEMPT UNSUCCESSFUL

the rst gure indicating the operational assembly is followed

by a P (warning) and the code relating to the specic warning.

The rst gure of the error code (e.g. 1 01) indicates within which

operational assembly the error occurred.

1 - Primary Circuit

2 - Domestic Hot Water Circuit

3 - Internal Electronic Part

4 - External Electronic Part

5 - Ignition and Detection

6 - Air inlet - ue gas outlet

7 - Multi-zone Heating
