N/A − First and second stage HEAT positions shown cannot be used on this model.
NOTES − The effect of static pressure is included in air volumes shown.
First stage HEAT is approximately 91% of the same second stage HEAT speed position.
First stage COOL (two−stage air conditioning units only) is approximately 70% of the same second stage COOL speed position.
Continuous Fan Only speed is approximately 38% of the same second stage COOL speed position − minimum 500 cfm.
Lennox Harmony IIIt Zone Control Applications − Minimum blower speed is 458 cfm.
