1. A control system, comprising:
a temperature sensor configured to measure the air temperature outside a building, and further configured to output a temperature signal based at least in part upon the sensed temperature; an enthalpy sensor configured to measure enthalpy of air outside a building and further configured to output an enthalpy signal based at least in part upon the sensed enthalpy; and a processor configured to receive said temperature signal and said enthalpy signal and to control the operation of an energy recovery ventilation wheel based at least in part on said temperature signal, said enthalpy signal, or both in order to reduce moisture buildup on the energy recovery ventilation wheel when it is not being used for energy recovery; said controlling comprises an algorithm with a start and stop sequence that:
first deactivates said energy recovery ventilation wheel for a first predetermined time period when the temperature signal, enthalpy signal, or both are within predetermined ranges andthen reactivates said energy recovery ventilation wheel for a second predetermined time period;wherein said reactivation comprises full, continuous rotation of the energy recovery ventilation wheel.
