Damper control in space heating and cooling
First Claim
1. A method comprisingtracking an aggregate amount of time that air has been transferred into or out of a space during an air transfer period, wherein said aggregate amount comprises time during which a hot or cold air generation system is on, and time during which the hot or cold air generation system is off, andbased on the tracked aggregate amount of time, controlling at least one turn-on time or one turn-off time of a fan that transfers air into or out of the space.
