According to the increase of heat around "220V Cooling Fan" thereby increasing the fan speed itself, while increasing the air flow. Using the temperature detected by the thermistor mounted on the fan hub of the fan by the sensor can detect temperature. In this configuration, the fan must be installed correctly, when "220V Cooling Fan" installation is complete, the thermistor sensor can be induced by a special cable. Fan operation is changed as the case of heat, at a slower speed operation, the fan will have less noise and consumes less energy. In most of the design requirements, after "220V Cooling Fan" speed operation is usually lower than the temperature of the air for several hours maximum design temperature value. Under normal circumstances, low speed cooling fan can be enough to complete its work.
