1.It has 30 prefabricated muli-segment free-form temperature programmable functions, selectable multiple startup methods, arbitrary skip operation, and manual modifiacition of the current running clock; when STA=0, it can be used as a fixed-value controller. 2.In the heating section, in order to prevent the possibility when the power is turned off and then on(SV-PV),which may cause the destruction of the instantaneous high-power output system, the "3" item in the STA menu will automatically When PV starts, it is guaranteed that(SV-PV)=0 deviation when power is turned on again. 3. Display the runnng status of the program, which is more intuitive and clear. 4.The machines can be configured with externally set SV value; 5.Slope temperature compensation. 6.Provide four communcation formats.
