Piazzetta IP 78/68 Instructions For Installation, Use And Maintenance Manual page 54

A sensor positioned at the flue gas outlet and connected to the PCB constantly monitors the working
temperature allowing the stove to be used in all safety.
The readout "SAFETY STOVE" appears on the display.
If the flue gas temperature exceeds the fixed safety limit, the power supply to the fuel-loading auger
is cut off thus depriving the grate of pellets and starting the stove shutdown process.
After approx. 60 seconds the warning buzzer sounds (if activated).
Shut down the stove by holding the ON/OFF key down for several seconds.
The warning buzzer stops.
Access the STOVE STATUS menu and the readout "MASS TEMP" appears (see causes under
"TROUBLESHOOTING").
Wait until the stove has cooled down, then check for and remove whatever has caused the safety
device to be triggered or contact the After-Sales Service Centre.
The readout "PROBE SMOKE" appears on the display.
This means that the sensor has been momentarily disconnected or accidentally dislodged or the
connector has not been positioned correctly on the PCB.
After approx. 60 seconds the warning buzzer sounds (if activated).
Shut down the stove by holding the ON/OFF key down for several seconds.
The warning buzzer stops.
Access the STOVE STATUS menu and the readout "NO CONN" appears (see causes under
"TROUBLESHOOTING").
Call the After-Sales Service Centre.
a
Empty and clean the grate before setting a new ignition cycle.
The readout "SAFETY AUGER" appears on the display.
This means that a fault has been found with the continuous pellet feed from the auger during the
operating phase.
After approx. 60 seconds the alarm sounds (if activated).
Shut down the stove by holding the ON/OFF key down for several seconds.
The alarm stops.
Access the STOVE STATUS menu and the readout "00. 0C0" appears.
Call the After-Sales Service Centre.
