The calculation used for the ventilation time setting is (all calculations compliant with ASHRAE Standard 62.2):
Minutes per Hour = 60 * (Required Continuous CFM/Measured CFM)
Measured CFM is entered during set up and Required Continuous CFM is calculated according to the equation below:
Required Continuous CFM = ((Floor Area ft2 * .01)+(No. of Bedrooms + 1) * 7.5)
