5 SFECM SERIES AIRFLOW SETTINGS The SFECM furnace is equipped with an efficient ECM motor that can maintain constant airflow regardless of the static pressure variation in the ducts. It also ensures an easy setting of the airflows related to each operation mode of the furnace blower. The blower has four adjustments. A potentiometer that makes airflow adjustment possible corresponds to each of these four modes. The potentiometers are located on the furnace control card. The adjustment scales vary from one model to the other according to the capacity of the unit. The airflows can be adjusted while the furnace is running. To adjust airflows, you must set the potentiometers to the desired values. AIRFLOW SETTINGS EXAMPLE SFECM2021 SETTING CONTINUOUS W VENTILATION VENTILATION LOW HIGH W1 W2 Y VENTILATION Recommended HEATING TEMPERATURE HEATING VENTILATION CONTINUOUS VENTILATION Y VENTILATION ECM MOTOR ELECTRONICALLY COMMUTATED MOTOR COMFORT, EFFICIENCY, RELIABILITY AND SECURITY ARE AT THE HEART OF THE ECM COMFORT EFFICIENCY RELIABILITY SECURITY Comfort level can be increased if a variable speed motor is installed. This level cannot be reached with any other method. It also allows the user to select the low speed with the desired airflow in recirculation. Since it combines electronic circuits and a BLDC motor, it is the most efficient motor on the HVAC market. It can reach up to twice the capacity of a PSC motor. All its electronic circuits are protected against condensation. Thanks to its design and materials, like silicone elastomer, it is one of the most reliable motors on the market. Its electronic system is protected by MOVs (metal oxide varistors) against lightning overvoltages.
