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.

1. A method of providing dehumidification control within the interior space of a building or room that is unoccupied for an extended period of time, the method comprising the steps of: providing a controller in communication with an air conditioner, the controller having a normal schedule cooling mode of operation that includes a home period and an away period, each period having a number of cooling mode settings, the controller further having an extended away cooling mode of operation having a number of extended away cooling mode settings that are configured to conserve energy relative to the cooling mode settings of the home and/or away periods of the normal schedule cooling mode of operation, the extended away cooling mode of the controller configured to control the air conditioner for providing dehumidification within the interior space while the building or room is unoccupied for an extended period of time;configuring the number of extended away cooling mode settings within the controller for controlling the environment within the interior space during the extended away cooling mode of operation, the extended away cooling mode settings including an extended away dehumidification setting and an extended away temperature setting;initiating the extended away cooling mode of operation within the controller; andwhen in the extended away cooling mode of operation, operating the air conditioner to: maintain the temperature within the interior space at or below said extended away temperature setting by selectively activating the air conditioner; andmaintain the humidity within the interior space at or below said extended away dehumidification setting by selectively activating the air conditioner, even when the temperature of the interior space is less than the extended away temperature setting. 2. The method of claim 1, further comprising: determining whether an indoor dewpoint temperature within the interior space is greater than an extended away cooling low temperature limit setting;operating the air conditioner to cool the interior space using a measure related to the indoor dewpoint temperature as a set point if the indoor dewpoint temperature is greater than the extended away cooling low temperature limit setting; andoperating the air conditioner to cool the interior space using a measure related to the extended away cooling low temperature limit setting as the set point if the indoor dewpoint temperature is at or below the extended away cooling low temperature limit setting, and the humidity within the interior space is above the extended away dehumidification setting. 3. The method of claim 1, further comprising: determining whether the indoor humidity within the interior space is greater than an extended away dehumidification setting;selectively operating the air conditioner to control the temperature in the interior space using a measure related to an extended away cooling temperature setting as a set point when the indoor humidity is less than the extended away dehumidification setting; andselectively operating the air conditioner to control the humidity in the interior space using a measure related to the extended away cooling low temperature setting as a set point if the indoor humidity is greater than the extended away dehumidification setting. 4. The method of claim 3, further comprising: determining a dewpoint within the interior space; andselectively operating the air conditioner to control the humidity in the interior space using a measure related to the dewpoint when the dewpoint is higher than an extended away cooling low temperature setting. 5. The method of claim 1, wherein the controller is a thermostat. 6. The method of claim 5, wherein the controller is a programmable residential thermostat. 7. The method of claim 6, wherein the home period of the normal schedule cooling mode of operation includes one or more of a wake period, a return and a sleep period. 8. The method of claim 6, wherein the away period of the normal schedule cooling mode of operation includes a leave period. 9. A method of providing temperature and humidity control within the interior space of a building via a controller in communication with an air conditioner, the method comprising the steps of: storing an extended away cooling temperature setting, an extended away cooling low temperature limit setting, and an extended away dehumidification setting within the controller;determining whether the indoor humidity within the interior space is greater than the extended away dehumidification setting;selectively operating the air conditioner to control the temperature in the interior space using the extended away cooling temperature setting as a set point when the indoor humidity is less than the extended away dehumidification setting; andselectively operating the air conditioner to control the humidity in the interior space using the extended away cooling low temperature limit setting as a set point if the indoor humidity is greater than the extended away dehumidification setting. 10. The method of claim 9, further comprising: determining a dewpoint within the interior space; andselectively operating the air conditioner to control the humidity in the interior space using a measure related to the dewpoint when the dewpoint is higher than the extended away cooling low temperature limit setting. 11. The method of claim 10, further comprising: determining whether the dewpoint temperature within the interior space is greater than the extended away cooling low temperature limit setting;operating the air conditioner to cool the interior space using the indoor dewpoint temperature as a set point if the indoor dewpoint temperature is greater than the extended away cooling low temperature limit setting; andoperating the air conditioner to cool the interior space using the extended away cooling low temperature limit setting as the set point if the indoor dewpoint temperature is at or below the extended away cooling low temperature limit setting, and the humidity within the interior space is above the extended away dehumidification setting. 12. The method of claim 9, wherein the controller is a thermostat. 13. The method of claim 12, wherein the controller is a programmable residential thermostat. 14. An HVAC controller configured to communicate with and control one or more components of an HVAC system including an air conditioner, the controller comprising: a user interface including a display;a memory for storing extended away cooling mode settings;an I/O block for receiving one or more signals from the HVAC system and for providing one or more control signals to the HVAC system; anda controller coupled to the memory, the user interface and the I/O block, wherein the controller is configured to operate in a normal schedule cooling mode of operation that includes a home period and an away period, each of the home period and the away period having one or more cooling mode settings, the controller is further configured to operate in an extended away cooling mode of operation that references the extended away cooling mode settings in the memory, which are configured to conserve energy relative to the cooling mode settings of the home and/or away periods of the normal schedule cooling mode of operation, the extended away cooling mode settings including an extended away dehumidification setting and an extended away temperature setting, the extended away cooling mode of the controller configured to control the air conditioner for providing dehumidification within the interior space while the building or room is unoccupied for an extended period of time;wherein when in the extended away cooling mode of operation, the controller is configured to operate the air conditioner to: maintain the temperature within the interior space at or below said extended away temperature setting by selectively activating the air conditioner; andmaintain the humidity within the interior space at or below said extended away dehumidification setting by selectively activating the air conditioner, even when the temperature of the interior space is less than the extended away temperature setting.
