Methods of providing dehumidification control in unoccupied spaces are disclosed. An illustrative method can include the steps of providing a controller having an away mode of operation adapted to provide dehumidification within the interior space of a building or room, providing one or more system components adapted to control the humidity and/or temperature within the interior space, initiating the away mode of operation within the controller, and operating the one or more system components for at least one cycle to reduce the humidity within the interior space.

What is claimed is: 1. A method of providing dehumidification control within an interior living space of a building or room while the building or room is unoccupied for a period of time, the method comprising the steps of: providing a controller having a normal mode of operation and an away mode of operation, the away mode of operation providing dehumidification within the interior living space while the building or room is unoccupied for a period of time; configuring a number of away mode settings within the controller for controlling the environment within the interior living space during the away mode of operation, the away mode settings including an away cooling temperature setting, an away cooling low temperature limit setting, and an away dehumidification setting; providing one or more system components for controlling the humidity and temperature within the interior living space, said one or more system components including an air conditioner in communication with the controller; initiating the away mode of operation within the controller; and determining whether the indoor dewpoint temperature plus an offset is greater than the away cooling low temperature limit setting; and while in the away mode of operation, operating the air conditioner to cool and dehumidify the interior living space if the indoor dewpoint temperature plus said offset temperature is greater than the away cooling low temperature limit setting. 2. The method of claim 1, wherein said step of configuring a number of away mode settings within the controller is accomplished with a user interface of the controller. 3. The method of claim 1, wherein said step of configuring a number of away mode settings within the controller is accomplished from a remote location away from said controller. 4. The method of claim 1, wherein the controller includes one or more normal mode settings for controlling the humidity and temperature within the interior living space during the normal mode of operation, and wherein said away mode settings are different than said normal mode settings. 5. The method of claim 1, wherein the away mode settings further include an away fan setting for setting the operational mode of a fan or blower in communication with the controller. 6. The method of claim 1, wherein, during activation of said away mode of operation, the controller defaults to a cooling operational mode. 7. The method of claim 6, wherein, during activation of said away mode of operation, the controller can be configured to default to one cycle per hour for all cooling stages. 8. The method of claim 1, wherein said step of initiating the away mode of operation within the controller is accomplished with a user interface of the controller. 9. The method of claim 1, wherein said step of initiating the away mode of operation within the controller is accomplished from a remote location away from said controller. 10. The method of claim 1, wherein said step of initiating the away mode of operation within the controller is accomplished automatically at pre-selected dates and/or times or when no activity is sensed within the interior living space for a predetermined period of time. 11. The method of claim 1, further including the step of operating the air conditioner to cool the interior living space at the away cooling temperature setting if the indoor dewpoint temperature plus said offset temperature is at or below the away cooling low temperature limit setting. 12. The method of claim 1, further comprising operating the air conditioner for one or more periods of time each day to cool the interior living space at a temperature below said away cooling temperature setting while in the away mode of operation. 13. The method of claim 12, wherein said step of operating the air conditioner for one or more periods of time each day includes the steps of: operating the air conditioner for a first period of time each day to cool the interior living space; and operating the air conditioner for a second period of time each day to cool the interior living space. 14. The method of claim 12, wherein said step of operating the air conditioner for one or more periods of time each day is performed irrespective of the actual humidity within the interior living space. 15. The method of claim 1, wherein said one or more system components further includes a dehumidifier in communication with the controller. 16. The method of claim 15, further comprising the step of operating the dehumidifier if the sensed indoor humidity within the interior living space is greater than the away dehumidification setting while in the away mode of operation. 17. The method of claim 16, further including the step of operating the air conditioner if the sensed indoor temperature within the interior living space is greater than the away cooling temperature setting while in the away mode of operation. 18. The method of claim 1, wherein said controller is a thermostat. 19. The method of claim 1, wherein the away mode settings are configured to conserve energy relative to the normal mode of operation, wherein when in the away mode of operation, operating the air conditioner to: maintain the temperature within the interior living space at or below said away cooling temperature setting by selectively activating the air conditioner; and maintain the humidity within the interior living space at or below said away dehumidification setting by selectively activating the air conditioner, even when the temperature of the interior living space is less than the away cooling temperature setting. 20. The method of claim 1, further comprising: determining whether the indoor humidity within the interior living space is greater than the away dehumidification setting; and operating the air conditioner to cool the interior living space using the away cooling low temperature limit setting as the set point if the indoor dewpoint temperature plus said offset temperature is at or below the away cooling low temperature limit setting and the humidity is above the away dehumidification setting. 21. The method of claim 1, further comprising: determining whether the indoor humidity within the interior living space is greater than the away dehumidification setting; selectively operating the air conditioner to control the temperature in the interior living space using the away cooling temperature setting as a set point when the indoor humidity is less than the away dehumidification setting; and selectively operating the air conditioner to control the humidity in the interior living space using the away cooling low temperature setting as a set point if the indoor humidity is greater than the away dehumidification setting. 22. The method of claim 21 further comprising: determining a dew point within the interior living space; selectively operating the air conditioner to control the humidity in the interior living space using a measure related to the dew point when the dew point is higher than the away cooling low temperature setting. 23. The method of claim 1, further comprising: for a given day, operating the air conditioner to control the temperature in the interior living space using the away cooling temperature setting as a set point; during a predetermined over-cool period during the given day, operating the air conditioner to over-cool the interior living space below the away cooling temperature setting; and after the predetermined over-cool period, returning to operate the air conditioner to control the temperature in the interior living space using the away cooling temperature setting as a set point. 24. The method of claim 23 wherein there are two or more predetermined over-cool periods during the given day. 25. The method of claim 23 wherein during the predetermined over-cool period, operating the air conditioner to control the temperature in the interior living space using an away cooling low temperature setting as a set point.
