HELLER K1404262 TC Temperature Control Module for Reflow Oven The HELLER K1404262 TC Temperature Control Module is an electronic control component used in compatible SMT reflow oven temperature-control systems. Its primary role is to support accurate temperature monitoring and stable thermal regulation by processing feedback from the oven's thermocouple-based sensing system. During SMT reflow soldering, every heating zone must operate within the programmed temperature profile
