1. An apparatus for controlling an attic exhaust fan comprising: a controller having a plurality of signal inputs, a plurality of power inputs, and a power output;a display unit in communication with said controller;a plurality of user-triggerable switches in communication with said controller; anda plurality of light indicators in communication with said controller, wherein a first one of said plurality of light indicators indicates a status of said attic exhaust fan,wherein the plurality of power inputs includes a first power input for connecting to a local solar array and a second power input for connecting to a local public utility AC power supply,wherein the controller is configured to operate the attic exhaust fan based on sensed input signals at the plurality of signal inputs,wherein the controller is configured to provide power to the power output from the first power input as a default if a predetermined amount of power for operating the attic exhaust fan is provided at the first power input and provide power to the power output from the second power input if a predetermined amount of power for operating the attic exhaust fan is not provided at the first power input,wherein when the controller operates the attic exhaust fan based on the sensed inputs: the controller is configured to operate the attic exhaust fan continuously when power is being provided from the first power input to the power output, andthe controller is configured to operate the attic exhaust fan for a predetermined duty cycle and for a total period not to exceed a predetermined duration when power is being provided from the second power input to the power output;further comprising a temperature sensor connected to said controller through a first one of said signal inputs and a humidity sensor connected to said controller through a second one of said signal inputs, at least one of said temperature sensor and said humidity sensor providing said sensed input signals. 2. The apparatus of claim 1 wherein the first power input is connected to the local solar array. 3. The apparatus of claim 2 wherein a second one of said plurality of light indicators indicates a status of said local solar array. 4. The apparatus of claim 3 wherein the power output is connected to said fan. 5. The apparatus of claim 4 wherein a first one of said plurality of switches selects a Celsius or Fahrenheit temperature scale for said display unit. 6. The apparatus of claim 5 wherein a second one of said plurality of switches is configured to allow a user to select a radio frequency channel. 7. The apparatus of claim 4 wherein the second power input is connected to the local public utility AC power supply, said local public utility AC power supply comprising an electrical outlet. 8. The apparatus of claim 7 wherein a third one of said plurality of light indicators indicates a status of said local AC power supply. 9. A method of providing power to an attic exhaust fan comprising: receiving power from a power source, the power source including at least two different local sources of power;sensing a local temperature with a temperature sensor proximal the attic exhaust fan;displaying said local temperature on a display;sensing a local humidity with a humidity sensor proximal the attic exhaust fan;displaying said local humidity on said display;operating the attic exhaust fan from the power source based on said local temperature and said local humidity;lighting a fan indicator to indicate said fan is being controlled; andlighting one or more indicators to indicate which of the at least two different local sources of power is being used,wherein operating the attic exhaust fan step comprises using a first one of the at least two different local sources of power as a default if sufficient power for operating the fan is provided by the first one of the at least two different local sources of power, and when using the first one of the at least two different local sources of power operating the fan continuously, wherein the first one of the at least two different local sources of power includes a local solar panel; andusing a second one of the at least two different local sources of power if sufficient power for operating the fan is not provided by the first one of the at least two different local sources, and when using the second one of the at least two different local sources of power operating the fan for a predetermined duty cycle and for a total period not to exceed a predetermined duration, wherein the second one of the at least two different local sources of power includes a local public utility AC power supply. 10. The method of claim 9 wherein the second one of the at least two different local sources of power includes an electrical outlet. 11. The method of claim 10 further comprising checking a speed of said fan, and turning said fan off if said speed of said fan is not within a pre-specified range. 12. The method of claim 10 further comprising measuring a power consumed by said fan, and turning said fan off if said power consumed by said fan is not within a pre-specified range. 13. The method of claim 12 further comprising communicating to a remote control unit said local temperature and said local humidity when a user presses a status button. 14. The method of claim 13 further comprising communicating to said remote control unit said local power source selected from the group consisting of said solar panel, said electrical outlet, said solar panel and said electrical outlet, and not said solar panel and not said electrical outlet. 15. A system for controlling an attic exhaust fan comprising: a controller having: a temperature sensor,a humidity sensor,the temperature sensor and the humidity sensor located proximal the attic exhaust fan,a first power input for connecting to a local solar array,a second power input for connecting to a local public utility AC power supply, anda power output connected to the attic exhaust fan;a remote control configured for wireless communications of control information and status information with the controller;wherein the controller is configured to operate the attic exhaust fan based on a sensed temperature and a sensed humidity, or based on a sensed humidity; andwherein when operating the attic exhaust fan, the controller is configured to determine if sufficient power to operate the fan is available from the first power input and: if it is determined that power is available from the first power input, the controller provides power to the power output from the first power input to operate the fan continuously; andif it is determined that sufficient power for operating the attic exhaust fan is not available from the first power input, the controller provides power from the second power input to the power output to operate the attic exhaust fan for a predetermined duty cycle and for a total period of time not to exceed a predetermined duration. 16. The system of claim 15, wherein the remote control is configured to set a controller mode such that if it is determined that power is available from the first power input, then power is provided to the power output to turn the fan on dependent only on a sensed humidity and not temperature. 17. The system of claim 15, wherein the system includes a fan connected to the power output, a local solar array connected to the first power input and a local public utility AC power supply comprising a power adapter connected to an electrical outlet. 18. The system of claim 15, wherein the remote control is configured to allow the user to select between two options for the controller's operating mode, including: (1) turning the fan on dependent only on the sensed humidity and (2) turning the fan on dependent on the sensed humidity and the sensed temperature. 19. The apparatus of claim 1, the sensed input signals include a sensed humidity signal and a sensed temperature signal, wherein the controller provides power to the power output from the first and second power inputs if at least one of the sensed humidity signal or sensed temperature signal indicates that a sensed humidity or a sensed temperature exceeds a corresponding preset threshold.
