Piazzetta P963 THERMO Instructions For Installation, Use And Maintenance Manual page 45

A pressure switch is connected to the flue gas outlet; its function is to control the vacuum inside the
outlet duct so that the stove can be used in all safety.
The readout "SAFETY SMOKE" appears on the display.
The causes could be that the correct operating conditions inside the flue gas outlet duct have
been altered (poor installation, presence of obstructions or obstacles in the outlet duct, careless
maintenance, unfavourable weather conditions such as persistent wind, etc.) or that a fault in the
pressure switch has been detected.
The warning buzzer activates after approx. 60 seconds (if set).
Shut down the stove by holding the ON/OFF key down for several seconds.
The alarm stops.
Access the STOVE STATUS menu and check the type of fault that has been detected.
The readout "ALF 1" or "ALF 2" could appear (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.
a
Empty out and clean the grate before setting a new ignition cycle.
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.
