According to certain embodiments disclosed in the present application, a climate controlled seating assembly includes a thermal module. The thermal module comprises at least one inlet channel, at least one outlet channel and a thermoelectric device (e.g., Peltier circuit) positioned upstream of the outlet channel. In one embodiment, the seating assembly includes a sensor positioned within an interior of the thermal module and configured to detect the presence of a liquid, such as water, condensation or other fluids, on or near said sensor. In certain arrangements, the sensor is configured to detect the presence of a liquid by measuring an electrical resistance or capacitance across a portion of the sensor. A climate control system can include a separator gasket located within a housing of a fluid module and at least partially between the cold passage and the hot passage. In some embodiments, the separator gasket comprises one or more wicking materials. The separator gasket can be configured to transport liquids from the cold passage to the hot passage.

1. A climate control assembly comprising: a thermal conditioning device configured to selectively heat and/or cool air;an air transfer device in communication with the thermal conditioning device, said air transfer device configured to transfer air relative to the thermal conditioning device to selectively transfer heat to or from the air being transferred;a sensor that detects a physical characteristic indicative of the humidity of the air; anda control unit operatively connected to the thermal conditioning device, the air transfer device and the sensor, the control unit configured to regulate operation of the thermal conditioning device based upon information received from the sensor to avoid condensation at the thermal conditioning device. 2. The climate control assembly of claim 1, wherein the sensor detects a physical characteristic indicative of the humidity of ambient air. 3. The climate control assembly of claim 1, wherein the sensor is positioned at an outlet of the air transfer device. 4. The climate control assembly of claim 1, wherein the sensor is positioned at an inlet to the air transfer device. 5. The climate control assembly of claim 1, wherein the sensor is positioned within the thermal conditioning device. 6. The climate control assembly of claim 1, wherein the thermal conditioning device comprises a thermoelectric device. 7. The climate control assembly of claim 1, wherein the thermal conditioning device comprises a convective heater. 8. The climate control assembly of claim 1, wherein the control unit regulates an amount of heating and/or cooling provided by the thermal conditioning device based upon information received from the sensor. 9. The climate control assembly of claim 1, further comprising a temperature sensor. 10. The climate control assembly of claim 9, wherein the control unit is configured to regulate operation of at least one of the air transfer device and the thermal conditioning device based upon information received from the sensor and the temperature sensor. 11. The climate control assembly of claim 1, wherein the physical characteristic is relative humidity. 12. The climate control assembly of claim 1, wherein the sensor is configured to detect condensate formation. 13. The climate control assembly of claim 12, wherein the sensor is configured to detect condensate formation by measuring a change in electrical resistance or capacitance across a portion of the sensor. 14. The climate control assembly of claim 1, wherein the control unit is configured to at least partially and selectively reduce a voltage supplied to the thermal conditioning device once the sensor detects a threshold level of humidity, while a speed of the air transfer device remains unchanged, and wherein the voltage supplied to the thermal conditioning device is configured to remain at a lower level until a level of humidity detected by the sensor drops below the threshold level. 15. The climate control assembly of claim 14, wherein, when the level of humidity is below the threshold level, the control unit is configured to adjust the voltage supplied to the thermal conditioning device to permit the climate control assembly to operate according to a control algorithm, wherein the control algorithm is configured to operate the climate control assembly within a target comfort zone, and wherein the target comfort zone is based on, at least in part, the level of humidity and the temperature of the air being transferred by the climate control assembly. 16. A method of operating a climate control assembly, the method comprising: transferring, via an air transfer device, air through a thermal conditioning device;measuring, via a sensor, a physical characteristic indicative of the humidity of the air; andregulating operation of the thermal conditioning device based upon information received from the sensor to avoid condensation at the thermal conditioning device. 17. The method of operating a climate control assembly of claim 16, wherein the physical characteristic is relative humidity. 18. The method of operating a climate control assembly of claim 16, wherein the sensor is positioned at an outlet of the air transfer device. 19. The method of operating a climate control assembly of claim 16, wherein the sensor is positioned at an inlet to the air transfer device. 20. The method of operating a climate control assembly of claim 16, wherein the sensor is positioned within the thermal conditioning device. 21. The method of operating a climate control assembly of claim 16, wherein the thermal conditioning device comprises a thermoelectric device. 22. The method of operating a climate control assembly of claim 16, wherein the thermal conditioning device comprises a convective heater. 23. The method of operating a climate control assembly of claim 16, further comprising regulating an amount of heating and/or cooling provided by the thermal conditioning device based upon information received from the sensor. 24. The method of operating a climate control assembly of claim 16, wherein the sensor measures a physical characteristic indicative of the humidity of ambient air.
