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 allowing to adjust the airflow 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 and are represented on the table
below. The airflows can be adjusted while the furnace is running. To
adjust airflows, you must set the potentiometers to the desired values.
1. Heating temperature
2. Heating ventilation
3. Continuous ventilation
4. Y ventilation
