This Temperature average controller system is to keep a stable temperature by average controlling temperature at multiple points in the width dirction of inside oven preventing under bake. Our own made temperature controller has "PID" control with the auto-tuning function. It gets definite high evaluation because an alarm set-up(upper and lower limit temperature) is indicated with the set-up value. The life span of parts is five times longer than the former model(PYC).
