airflow settings
The SEFECM 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
five modes:
1. Continuous ventilation low speed
2. Continuous ventilation high speed
3. Heating demand 50% power
4. Heating demand 100% power
5. Air conditioning
A potentiometer allowing to adjust the airflow corresponds to each of
these five modes. The potentiometers are located in front of the furnace
electrical panel. The adjustment scales of the 3 and 4 modes vary
from one model to the other according to the capacity of the unit. To
adjust airflows, you must press down once the PROG (programming)
button located below the potentiometers; the programming pilot light
will turn on. Then, set the potentiometers to the desired values. To
confirm settings, press down again the programming button. The
ADjuSTMENT SET pilot light will turn on confirming that the new
settings have been recorded.
