The effect of static pressure and filter resistance is included in air volumes shown.
1st stage COOL is approximately 70% of the same 2nd stage COOL speed position.
Continuous Fan Only speed is approximately 38% of the same 2nd stage COOL speed position.
Lennox Harmony zone control applications − Minimum blower speed is 400 cfm. Max cfm is the same as 2nd stage cool position.
