4.20. Exiting alarm condition

INSTALLATION AND USE MANUAL

Chapter 4 page 48

If there is an alarm, to restore normal operation of the unit 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 and the message OFF disappear. This 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 unit can again be managed by the remote control.

• Turn the remote control off and back on again if you want to relight the flame.

In the event of defect A12 (no communication between remote control and unit), the flame 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.

4.20.1. Interruption of product functioning

The following things can cause mechanical shutdown:

• Overheating of the stove body

• Operation at maximum power for prolonged periods.

• 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.

Shutdown is signalled on the display of the emergency panel and accompanied by a beep. In this situation the shutdown cycle is automatically activated. It is necessary to deactivate the alarm before restarting the product.

ALARM A3: In case an excessive temperature occurs at the pellet hopper level, the product will sound an A03 alarm.

The machine is equipped with an automatically rearming safety thermostat.

To correct this condition, the user must turn off the equipment by putting the "D" selector in the OFF position and waiting until the structure and hopper cool down

(approximately 20 minutes).

In fact, when the machine is cooled down the thermostat will rearm and the alarm will deactivate. It is then possible to restart the machine.

ALARM A5: You will need to check whether ALL the smoke duct, flue pipe and combustion chamber are clean and free of all obstructions. (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 another attempt to relight the stove be made.
