NOTES − The effect of static pressure and filter resistance is included in air volumes shown.
1st stage HEAT is approximately 91% of the same 2nd stage
HEAT speed position.
1st stage COOL (two speed air conditioning units only) is approximately 70% (65% for units built prior to 09−2002) of the same 2nd stage COOL speed position.
Continuous Fan Only speed is approximately 38% of the same 2nd stage COOL speed position − minimum 500 cfm (235 L/s).
Lennox Harmony II zone control applications − Minimum blower heating speed is approximately 75% of the 1st stage HEAT speed position.
Lennox Harmony II zone control applications − Minimum blower cooling speed is approximately 45% of the 2nd stage COOL speed position.
