4.18. Exiting alarm condition
If there is an alarm, to restore normal operation of the stove you will
need to follow the procedure outlined below:
x Place selector D of the rear emergency panel in the OFF
position for a few seconds until the 3-figure code that identifies
the type of alarm disappears. The following operation will also
stop the flashing of the red LED and the acoustic alarm signal.
x Place selector D back in the REMOTE position, so that the stove
can again be managed by the remote control.
x Turn the remote control off and back on again if you want to
restart the stove.
Only in the event of defect A12 (no communication
between remote control and stove), the stove will
remain on with the most recently set mode. It will
automatically exit alarm mode as soon as it receives
a signal from the remote control.
4.18.1. Mechanical shutdown of the stove
The following things can cause stove shutdown:
x Overheating of the stove body (“A03”)
x Overheating of the smoke (“A04”)
x During the function of the stove, an uncontrolled air intake
occurred in the combustion chamber or an obstruction in the flue
pipe (“A07”)
Shutdown is signalled on the display accompanied by a beep.
In this situation the shutdown cycle is automatically activated.
Once this process has started, any operation which is an attempt to
reset the system is useless.
The cause of the shutdown is shown on the display.
WHAT TO DO:
If “A03” appears: the structure is too hot because the product has
been operating for too long at maximum power, or it is poorly
ventilated, or the air fans are faulty. When the stove is sufficiently cold,
press button B on the control panel or OFF on the remote control to
cancel the alarm A03. Once the alarm is cancelled it is possible to
relight the stove normally
.
If “A04” appears: the stove will shut off automatically. Let the stove
cool off for a few minutes, then re-light it.
Control the exhaust of the smoke and
check the type of pellet being used.
If “A07” appears: it is caused by the prolonged opening of the fire
door or by substantial air infiltration (e.g. smoke fan inspection plug
missing). If not caused by these factors control and if necessary clean
the smoke duct and the flue pipe. (it is recommended that this
operation be conducted by a specialist MCZ technician).
Only after the cause of the blockage has been permanently
eliminated can a fresh attempt to relight the stove be made.
