⑴ 温度设定范围为40～90℃。

⑵ 环境温度降低时（例如用电风扇降温）温度控制的静态误差≤1℃。

⑶采用适当的控制方法，当设定温度突变（由40℃提高到60℃）时，减小系统的调节时间和超调量。

⑷用十进制数码管显示水的实际温度。

⑸ 在设定温度发生突变（由40℃提高到60℃）时，自动打印水温随时间变化的曲线。

-1 the temperature setting for 40 ~ 90 ° c range.

2 environment temperature decreases with electric (for example) temperature control of static error than 1 ° c.

(3) using appropriate control method, when the temperature of 40 degrees Celsius mutations (to 60 ° c), reduce system to adjust the time and overshoot.

4 decimal digital display with the actual temperature of the water pipe.

[5] in setting temperature mutations (by 40 ° c to 60 ° c), automatic printing temperature changes with time curves.
