SIC03

Message displayed on the remote control: CHECK PELLET or CHECK PELLET LOW FLUE GAS TEMP.

SIC03 is the shutdown due to low flue gas temperature (below 45 degrees).

Possible causes are:

- Pellet exhausted 

- Auger jammed and/or auger motor faulty

Before turning on the stove, activate the “Loading” function in the user menu or via output test in the system menu, to check the proper operation of the auger and motor.

- Incorrect fuel mixture

If the motor runs correctly and the hopper is full of pellets, the error may simply be due to an insufficient amount of fuel and an excess of combustion air, so the pellet and air mixture should simply be adjusted via the “Calibrations” option.

- Flue gas thermocouple faulty
 

After checking the wiring, check if the flue gas thermocouple located in the cast iron spiral at the flue outlet is dirty or improperly positioned by reading the flue gas temperature in the “Displays” menu. Replace the flue gas thermocouple in case of malfunction.

Attention: if the SIC03 alarm appears while the flue gas temperature, detected by the thermocouple, is above 45°C, the problem could depend on parameters 08 - FLUE GAS TIME LESS and 09 - FLUE GAS DELTA LESS, present in the NEW MANAGEMENT menu of the System menu.

The operation is as follows:
when the flue gas temperature drops by 1°C, a timer is activated whose duration is defined by parameter 08. If, during this time interval, the temperature continues to drop exceeding the value set in parameter 09, the stove goes into SIC03.

To prevent this error, it is possible to:

• slightly increase the value of parameter 09, to tolerate a greater temperature variation;

• slightly reduce the value of parameter 08, to reduce the time during which the drop is monitored.
