Electric Furnace Modulating with Electronic Controls-ECM Motor

Modulation at its best

SEFECMB Discontinued product

A SEF furnace equipped with a modulating system and an ECM (electronically commutated motor) ensuring increased efficiency and a uniform airflow, that’s what the SEFECM has to offer. It’s the pinnacle of comfort and reliability. Thanks to the ECM, you will have the opportunity to use the continuous ventilation mode for less. Moreover, since it is more quiet than a PSC (permanent-split capacitor), you can enjoy continuous airflow which maintains constant temperature and increases the efficiency of your humidifier and filtration system. The ECM controls allow flexibility when choosing the desired airflow for each mode. A potentiometer allows to adjust the desired airflow with a high degree of accuracy, resulting in easier adjustments and maximum comfort. The SEFECM can also be installed in mobile homes using the FSB1 adapter.
