Quick Start Setup Example: (heating system):
1, press the SET button, SV digital tube flashing, shift and add and subtract key to set the temperature value, return after set with press SET button; 2, long-time press the SET button for 3 seconds to enter the menu: P0 window is set to H, is heating mode; P1 window is set to 02, select the 10K thermistor as the sensor; P2 / P3 for high and low temperature alarm, not set; P4 window is set to 1, select the slow mode; P5 window is set to ON, that is, open the auto-tuning function; 3, the delay waiting for 10 seconds, the system automatically exit the menu and start self-tuning; 4, connect heating device into the power supply socket, waiting for self-tuning end.
System PID parameters and auto tuning
System can be used before the use of self-tuning function, easy to find the best system PID parameters, improve the quality of regulation. After auto-tuning starts, the AT green light flashes, and after the measured value PV reaches the SV set value, it will automatically cause two or three disturbances to the system. According to the size of the overshoot oscillation and recovery cycle, automatically calculate the system PID parameters. AT tuning is complete, the buzzer drops, AT lights off, the system back to normal control.
PID parameters manual adjustment: (beginner skip)
Can be observed in the P7, P8, P9 window or manually modify the tuning parameters. For hysteresis and variable frequency control and other special systems, if the repeated setting effect is not ideal, can manually modify the PID parameters.
1, when the steady state before the arrival of overshoot is too large, such as to reach steady-state time is not high, the P7 value can be appropriately reduced.
2, if you want to speed up the steady state of the time, and allow a small amount of overshoot, the P7 value can be appropriately increased.
3, when the measured value fluctuates slowly up and down in the set value, may be appropriate to increase the P8 integration time or reduce the P7 proportional gain.
4, when the measured value fluctuates frequently in the set value, may be appropriate to reduce the P9 derivative time.

When the PID self-tuning is completed, according to the choice of response speed, provide different control parameters;
Slow: the system almost no overshoot, such as the user to set the temperature of the time to set the request is not high, optional;
Medium speed: the system in the overshoot and response between the balance between the state;
Fast: the system has a large overshoot, such as the user response speed requirements, optional

PID parameters manual adjustment: (beginner skip)
You can observe or manually modify the tuned parameters in the [1-2] ~ [1-16] PID window group. For hysteresis and variable frequency control and other special systems, if the repeated setting effect is not ideal, can manually modify the PID parameters.
A. When the steady state before the overshoot is too large, such as to reach the steady-state time is not high, can increase the ratio to overcome the overshoot.
B. If you want to speed up the steady state of the time, and allow a small amount of overshoot, may be appropriate to reduce the proportion of band.
C. When the measured value fluctuates slowly above and below the set value, the integral time or the proportional band can be increased as appropriate.
D. When the measured value fluctuates frequently up and down the set value, the derivative time can be reduced as appropriate.
