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:
• 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.
• Place selector D back in the REMOTE position, so that the stove
can again be managed by the remote control.
• 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. Shutdown of the stove
The following things can cause stove shutdown:
• Overheating of the stove body (“A03”)
• High pressure in the outlet fumes (as read by the pressure
switch) and therefore possible obstruction of the smoke
discharge system or external back-pressure. (“A05”)
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 the message "A03" appears: place selector D of the rear emergency
panel in the OFF position and wait for the stove to cool. When the
stove is cool enough, the A03 alarm indication on the display will
disappear. Place selector D of the panel in the REMOTE position to
restart the stove using the remote control.
If the message “A05” appears: check that the ENTIRE smoke duct,
including the combustion chamber, is clean and free of any obstruction.
(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.
