BOILER PROTECTION

BOILER PROTECTION DEVICES Boiler protection devices The boiler is protected from malfunctioning by means of internal checks performed by the 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 automatically as soon as the problem which caused the shut-off is removed; the error is indicated by the «Err» symbol which appears on the display and the error code. In fact, as soon as the cause of the shut-off disappears, the boiler starts up again and continues to operate normally. While the boiler is shut off for safety reasons it is possible to attempt to restore normal operation by switching the appliance off and on again using the on/off button on the control panel. If after attempting this the boiler still shows a safet shut off, switch it off and ensure that the external electrical switch is in the off position. 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. The first figure of the error code (e.g. 1 01) indicates within which operational assembly the error occurred. 1 - Primary Circuit 3 - Internal Electronic Part 5 - Ignition and Detection 6 - Air inlet - flue gas outlet Malfunction warning This warning is shown by the display in the following format: 5 P1 = FIRST IGNITION ATTEMPT UNSUCCESSFUL the first figure indicating the operational assembly is followed by a P (warning) and the code relating to the specific warning. 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. Anti-frost Device. The anti-frost function acts on the central heating flow temperature probe, independently from other regulations, when the electrical supply is turned on. If the primary circuit temperature is between 3°C and 8°C the pump will run until the temperature reaches > 9°C. If the flow temperature remains between 3°C and 8°C the pump will continue to run for a maximum of 20 minutes unless a temperature above > 9°C is detected in the central heating flow, after this the the burner will fire (heating position) until a temperature of > 30°C is detected. If the central heating flow temperature is < 3°C, the burner will fire (heating position) at minimum power until the temperature reaches > 30°C, the burner will go out. If lockout is caused by overheat the burner will not fire but the pump will continue to run. The anti-frost device activates only when (with the boiler operating correctly): - the boiler is electrically powered; - there is a supply of gas. 34 / Table summarising error codes Central Heating circuit Display Description 1 01 Overheat 1 03 1 04 1 05 1 06 1 07 Insufficient circulation 1 08 Insufficient water (request filling) 1 09 System pressure > 3 bar 1 10 C.H.

SETTINGS - ADJUSTMENT - PROBLEM IDENTIFICATION MENUS Accessing the settings - adjustment - problem identification menus The boiler can be used to manage the heating and domestic hot water production system in its entirety. Navigation within the menus enables the boiler system + connected peripheral units to be customised, optimising operation for maximum comfort and maximum saving. It also provides important information relating to the efficient operation of the boiler. Before access to the menus, the display show some “quick settings” to have direct access to the parameters. To see all available parameters and menu access to view FULL MENU.
