Application for automatic combustion control OEC 4. The OEC 4 automatic combustion control regulates the combustion process itself by means of a microprocessor unit, which results in optimization of combustion depending on the air supply to the combustion chamber by means of an electronically controlled air damper. Automatic combustion control OEC 4 - optimises combustion depending on the flue gas temperature to maximise efficiency. - meets current emission requirements - prevents the appliance from overheating - ensures safe heating - maintains the combustion process at rated performance - extends the life of the appliance by optimising combustion - all visual and acoustic information is communicated to the customer via the OEC 4 app and directly on the appliance - the ideal time for refuelling is indicated acoustically and visually by an LED directly on the appliance - consumption is reduced by up to 30% compared to appliances without combustion control
