Coefficient (COEF)
continued
Fast Mode
Provide the fastest heat up time but the widest fluctuation range of
temperature overshoot and undershoot
Optimal Mode
Provide the optimal balance between the heat up time to reach the
target temperature and the allowed fluctuation range of temperature
overshoot and undershoot (factory default)
Slow Mode
Provide the slowest heat up time but the narrowest fluctuation range
of temperature overshoot and undershoot
User Mode
Allow auto-tuned parameters to be used for temperature control
Point Mode
Allow linear heating up to the target temperature using the maximum
heating rate and switching on and off the heater based on the target
temperature (Note that this mode shows the widest fluctuation range
of temperature overshoot and undershoot.)
