For heat recovery ventilators(HRV)and energy recovery ventila- tors(ERV)the average hourly ventilation capacity must be determined in consideration of any reduction of exhaust or out outdoor air intake,or both,for defrost or other equipment cycling. Continuous ventilation-A minimum of 50 percent of the total ventilation rate,but not less than 40 cfm,shall be provided,on a con- tinuous rate average for each one-hour period. The portion of the mechanical ventilation system intended to be continuous may have automatic cycling controls providing the average flow rate for each hour is met. Pagel of 6
