1. It has 30 prefabricated multi-segment and multi-segment free-form temperature programmable functions, selectable multiple startup methods, arbitrary skip operation, and manual modification of 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 possbility of a large deviation when the power is turned off and then on(SV-PV), which may cause the destruction of the instantaneous high-power output systemm the "3" item in the STA menu will automatically When PV starts, it is guarenteed that(SV-PV)=0 deviation when power is turned on again. 3. Display the running status of the program, which is more intuitive and clear. 4. The machine can be configured with externally set SV value; 5.Slope temperature compensetion. 6.Provide four communication formats.
