3.Product Working Principle and Installation


	The temperature sensor in temperature controller feels the temperature 0fthe controlled media increases, the liquid in the tensor swells. When the temperature 0fthe media exceeds the set point, the connecting point will separate, and then the power will be switched off and the heating stopped, And then the temperature decline slowly,ifbelow the set point, the connecting point will connect again and power connection is recovered,

	When installing temperature controller,temperature sensor shall be put horizontally and vertically,Otherwise the temperature is unstable

	Install only after check the connection and break of temperature controller is normal
