Determine Cycle Time
1. Use the Required CFM and Delivered CFM from the above steps to determine the Cycle Time from
Table 3
.
2. The values highlighted in gray cannot be set due to the maximum 60 minute Cycle Time. A second ventilation device
(i.e., bigger duct or second duct) will be required to meet ventilation needs.
