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 (235 L/s).
Lennox Harmony Ill ' Zone Control Applications - Minimum blower speed is 478 cfm (225 Us).
