HS C

Appliance shut-off conditions

The boiler is protected from malfunctions by means of internal

checks performed by the electronic 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 control panel display

which refers to the type of shut-off and the reason behind it.

Two types of shut-off may occur:

Safety shut-off

This type of error is "volatile", which means that the boiler starts

up again automatically as soon as the

problem which caused the shut-off is

removed; Err" and the error code (e.g.

Err/110) ) flash on the display and the

symbol appears.

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

disappears, the boiler starts up again

and continues to operate normally.

If the boiler still indicates a safety shut-off, switch it off. Make

sure the external electric switch is in the OFF position, shut off

the gas valve and contact a qualified technician.

Safety shut-off due to insufficient

water pressure

If the water pressure inside the

heating circuit is insufficient, the

boiler will perform a safety shut-off.

Code 108 (e.g. Err/108) will appear

on the display, in addition to the

symbol. The system may be

restarted, re-balancing the value, by using the filling procedure

- see note 1.

If the re-balancing request is performed on a frequent basis,

switch the boiler off, bring the external electric switch to the OFF

position, shut off the gas valve and contact a qualified technician

to check for any leaks of water.

NOTE 1 - FILLING PROCEDURE

TO RESTORE THE CORRECT PRESSURE OPEN

THE FILLING VALVE (POSITIONED IN THE BOTTOM

OF THE BOILER) AND PRESS THE MODE BUTTON

FOR 5 SECONDS. THE DISPLAY SHOWS "P".

WHEN THE PRESSURE GAUGE INDICATES A

PRESSURE BETWEEN 0.6 AND 1.5 BAR, CLOSE THE

FILLING VALVE AND PRESS THE MODE BUTTON.

THE DISPLAY RETURNS TO NORMAL VIEW.
