1. A method of controlling operation of an energy recovery ventilation wheel, comprising: measuring an outside air temperature with a temperature sensor;measuring an outside air enthalpy with an enthalpy sensor;receiving a temperature signal at a processor from the temperature sensor, wherein the temperature signal is based at least in part on the outside air temperature;receiving an enthalpy signal at the processor from the enthalpy sensor, wherein the enthalpy signal is based at least in part on the outside air enthalpy; andcontrolling the operation of the energy recovery ventilation wheel with the processor, by: deactivating, with the processor, the energy recovery ventilation wheel for a first time period in response to the temperature signal, the enthalpy signal, or both, exceeding one or more set points; andin response to the energy recovery ventilation wheel being inactive for the first time period, reactivating, with the processor, the energy recovery ventilation wheel for a second time period, wherein reactivating the energy recovery ventilation wheel results in full, continuous rotation of the energy recovery ventilation wheel. 2. The method of claim 1, wherein the controlling further comprises activating a blower in the first time period while the energy recovery ventilation wheel is deactivated. 3. The method of claim 2, wherein the controlling further comprises reactivating the energy recovery ventilation wheel after at least the first time period such that a moisture buildup on the energy recovery ventilation wheel is removed. 4. The method of claim 3, wherein reactivating the energy recovery ventilation wheel occurs at least 10 minutes after the deactivating. 5. The method of claim 1, wherein the one or more set points comprise a temperature set point of approximately 40 degrees Fahrenheit. 6. A method of controlling operation of an energy recovery ventilation wheel, comprising: measuring an outside air temperature with a processor based on input from a temperature sensor;measuring an outside air enthalpy with the processor by combining input from a relative humidity sensor with the input from the temperature sensor; andcontrolling the energy recovery ventilation wheel using the processor, by: turning off the energy recovery ventilation wheel, with the processor, for a time period in response to the outside air temperature, the outside air enthalpy, or both, being within predetermined ranges; andafter the time period, turning on the energy recovery ventilation wheel, with the processor, and causing full, continuous rotation of the energy recovery ventilation wheel. 7. The method of claim 6, wherein the controlling comprises activating a blower during the time period. 8. The method of claim 6, wherein, after the time period, turning on the energy recovery ventilation wheel, with the processor, and causing full, continuous rotation of the energy recovery ventilation wheel is configured to remove a moisture buildup on the energy recovery ventilation wheel. 9. The method of claim 8, wherein the time period is 10 minutes. 10. The method of claim 6, wherein the predetermined ranges comprise an outdoor air temperature range of approximately 40 degrees Fahrenheit to approximately 70 degrees Fahrenheit. 11. A method of controlling operation of an energy recovery ventilation wheel, comprising: measuring outside air parameters using one or more sensors;communicating the outside air parameters from the one or more sensors to a processor;processing the outside air parameters with the processor; andcontrolling the energy recovery ventilation wheel using the processor, by: opening a relay, with the processor, such that power to the energy recovery ventilation wheel is disconnected for a first time period when the outside air parameters are within predetermined ranges; andclosing the relay, with the processor, after the first period, such that the power to the energy recovery ventilation wheel is connected, and the energy recovery ventilation wheel is reactivated for a second time period and rotates with full, continuous rotation. 12. The method of claim 11, wherein the controlling comprises activating a blower during the first time period. 13. The method of claim 11, wherein closing the relay, with the processor, after the first period, such that the power to the energy recovery ventilation wheel is connected, and the energy recovery ventilation wheel is reactivated for a second time period and rotates with full, continuous rotation is configured to remove a moisture buildup on the energy recovery ventilation wheel. 14. The method of claim 13, wherein the first time period is 10 minutes. 15. The method of claim 11, wherein the outside air parameters comprise an air temperature, and wherein the predetermined ranges comprise an air temperature range of approximately 40 degrees Fahrenheit to approximately 70 degrees Fahrenheit.
