What is the temperature control 220V Cooling Fan?

Thermostat "220V Cooling Fan" using a thermistor to sense temperature, mounted on the fan hub sensor can detect temperature through the fan. In this configuration, necessary properly install the fan, when the fan is installed, thermistor connection wires through special sensors. As is the case of the heat fan operation is changed to a slower speeds, "220V Cooling Fan" will produce less noise, and consumes less energy. In most of the design requirements, the fan speed after running for several hours in the air temperature is usually lower than the maximum design temperature value. Under normal circumstances, low-speed operation of "220V Cooling Fan" can be enough to complete its work.
