•“S” represents SSR drive output support models which SSRP function (standard ON/OFF control, cycle control, phase control) are available. “C” represents selectable current and SSR drive output support models.
?Select “R” or “C” type in case of using heating&cooling control and “N” type in case of using standard control.
?CT input of TK4N is available only for the standard model which has alarm output 1.
