Abstract
An amount of time that air has been delivered from an air handler to a space is tracked, and based on the tracked amount of time, at least one turn-on time or one turn-off time of the delivery of air from the air handler to the space is controlled. Other features relate, among other things, to controlling a replacement air vent, and to user interfaces.
Claims21
A method comprising
- tracking 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, and
- based 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.
A medium bearing instructions to cause a machine to
- track an aggregate amount of time that air has been transferred into or out of a space an during 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, and
- based on the tracked aggregate amount of time, control at least one turn-on time or one turn-off time of a fan that transfers air into or out of the space.
Apparatus comprising
- a controller to
- track 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, and
- based on the tracked aggregate amount of time, control at least one turn-on time or one turn-off time of a fan that transfers air into or out of the space.
A method for controlling a fan in a building having a heating or cooling system comprising:
- (a) establishing a length of a fan period and a run time amount, the run time amount being less than the length of a fan period;
- (b) during a fan period:
- (i) operating the fan during at least some portions of periods when the heating or cooling system is operating;
- (ii) if the time when the heating or cooling system operates during the fan period is less than the run time amount, operating the fan for additional periods when the heating or cooling system is not operating, such that the fan operation time during the fan period equals the minimum run time amount.
