On/Off mode
On/Off mode control is a very common and simple control mode. When the control output is programmed as
the heating output and the temperature lower than setting value, control output start to activate; if the
temperature is higher than setting value, control output deactivate in order to control the temperature. It also
can adjust hysteresis band to reduce the overshooting on the system to achieve the best control and stability.
PID mode
MV
SV
PV
PID control is corresponding to three constants which are proportional, integral, derivative. P is to handle the
immediate error, I is to learn from the past and D is to handle the future. When control output is the heating
output, the PT-series will apply PID+ Fuzzy algorithm to calculate a MV value (manipulate value) to be used in
determining whether the control output should be strong or weak in order to constantly calculating the
deviation of stability and prediction. The built-in Fuzzy control is to enhance the system in stability for
achieving the best control and efficient.
Program /Program ONOFF Mode
Program mode offers 8 patterns temperature control. Every pattern includes temperature setup, time of ramp,
time of soak. Measurement unit is minute. The 8 patterns temperature control allows the system to reach the set
temperature within the set time of ramp(increase/decrease), and to maintain the set temperature within the set time
of soak. It can also utilize Wait Width(EXPA->WAit) to let the system stay close to the setup even if the system is
unable to follow the setup perfectly. There are 8 sub-patterns for set up in one pattern. Via Link function, 64
sub-patterns temperature control can be given with ON/OFF and PID control as optional.
