ALERT USER’S MANUAL

ALERT USER’S MANUAL 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. The display shows the code and the error description. “Fault 110 - Send Probe Damaged” Operation shutdown This type of error is “non-volatile”, which means that it is not removed automatically. The display shows the code and the error description. To restore normal operation press the RESET button on the control panel. The dispay shows “Reset in progress” and then “Fault solved”. If the problem manifests itself again after several attempts to reset the appliance, contact a qualified and comment engineer. ALERT Fault 501 No flame detected Fault 501 Fault 110 Press the Reset button No flame detected Press the Reset button ALERT Send Probe Damaged Reset in progress When the cause of the shut-off is resolved, the boiler will start up again and continues to operate normally. If the boiler still indicates a safety shut-off, switch it off and contact a qualified on competent engineer. Safety shut-off due to insufficient water pressure In the event of insufficient water pressure in the heating circuit, the boiler signals a safety shutdown. The display shows “Fault 108 - Filling Needed”. The system may be restarted, re-balancing the water pressure, by using the filling procedure - see note 1. Fault 108 Fault solved Important If this shutdown occurs frequently, contact an authorised qualified and competent engineer, such as a Ariston Service partner 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. ALERT Filling Needed 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 RE-ESTABLISH THE CORRECT PRESSURE USING THE FILLING LOOP (POSITIONED UNDERNEATH THE BOILER) AND PRESS THE MODE BUTTON FOR 5 SECONDS. THE DISPLAY SHOWS “AIR PURGE ACTIVE“. WHEN THE PRESSURE GAUGE INDICATES A PRESSURE OF 1 BAR, CLOSE THE FILLING VALVE AND PRESS THE MODE BUTTON. THE DISPLAY RETURNS TO NORMAL VIEW. / 10 420011270801 - Rev.01 - 072024

If the primary circuit temperature falls below 8°C the pump will run for 2 minutes. After the two minutes of circulation (fixed) the boiler will check the following: a) if the central heating flow temperature is > 8°C, the pump stops; b) if the central heating flow temperature is between 4 and 8°C, the pump will run for another two minutes; c) if the central heating flow temperature is < 4°C, the burner will fire (heating position) at minimum power until the temperature reaches 33°C, the burner will go out and the pump will continue to run for two minutes. If the flow temperature remains between 4-8°C the pump will continue to run for two minutes for a maximum of 10 times unless a temperature above 8°C is detected in the central heating flow, after this the the burner will fire. If lockout is caused by overheat the burner is kept OFF. The anti-frost function activates only when (with the boiler operating correctly): - the system pressure is correct; - the boiler is electrically powered; - there is a supply of gas.
