9-SAFETY DEVICES AND ALARMS
Safety thermostat - Alarm A03
This type of alarm occurs when the water temperature in the boiler exceeds 95°C.
The boilers contain a safety thermostat that prevents the water in the boiler from boiling.
The safety thermostat in the boilers must be reset manually. This is done by pressing the small button between the two sockets (see
below). Problems like this can happen if there is no water circulation because the pump is blocked, if all the valves are closed or if there
is no electricity.
CAUTION:
All operations must only be carried out when the boiler is switched off and the plug disconnected.
If the problem persists, contact a service centre.
To reset the safety thermostat in the case of alarm A03 proceed as follows:
•
Switch the boiler off
•
Disconnect the power supply
•
Wait for the boiler to cool down
•
Access the safety thermostat by opening the door to the boiler, removing the two screws and the plate (see figure below). You can
access the thermostat from the hole.
•
Reset the thermostat by pressing the button between the two sockets until it clicks (if the button cannot be pressed, the boiler
temperature may still be too high or the thermostat may be damaged)
•
set the plate back into position
•
power the stove once again,
•
Cancel the alarm (if the alarm persists, contact the service centre).
Reset the alarm by pressing key 1 (ESC) for a few seconds. The boiler checks whether the cause of the alarm is ongoing. In the first case,
the alarm continues to be displayed (contact the service centre) and in the second case it goes OFF.
