The Family Pro's Active Combustion Control (ACC) system, designed and developed by Riello, allows for functionality, efficiency and low emissions under any conditions. The ACC system uses a flame (ionization) sensor signal to regulate combustion. The system maintains a continuous and optimal air/ gas mixture throughout modulation (allowing the CO2 readings to remain steady). FAMILY PRO's sophisticated control system provides the auto-regulation of the combustion so there is no need for an initial calibration. The ACC system is able to adapt the boiler to operate with different gas compositions. The ACC system can also perform an auto diagnostic operation that locks out the burner before the permitted upper emission limit is exceeded. ACC advantages: Auto-adaptability of the system to the type and composition of the gas eliminates the need for gas conversion kits. No mechanical calibration or manual adjustments for combustion are required on the boiler. Steady stoichiometric * air/ fuel value is maintained throughout boiler operation. Continuous emission control is in compliance with prevailing standards. Substantial gas savings compared to traditional systems. Efficiency and reliability are assured for the life of the boiler. The ACC system enables the boiler to change based on data received from parameters that take in consideration both deterioration of components and data acquired over time.
