1.It has 30 prefabricated multi-segment and multi-segment free-form temperature programmable functions, selectable multiple startup methods, arbitrary skip operation, and manual modificaiton of the current running clock; when STA=0, it can be use as a fixed-value controller. 2.In the heating section, in order to prevent the possility of a large deviation when the power is turned off and then on(SV-PV), which may cause the destruction of the STA menu will automatically whrn PV starts, it is guaranteed that(SV-PV)=0 deviation when power is turned on again. 3.Display the running status of the program, which is more intutive and clear. 4.The machine can be configured with externally set SV value; optional dual output cooling and heating control mode. 5.Slope temperature compensation. 6.Provide four communication formats.
