工作原理：
由温度传感器TE-1,比例积分温度控制器TC-1和电动两通调节阀TV-1组成送风温度控制系统，安装在送风管道的TE-1把检测到的温度信
号传送至TC-1,由TC-1将TE-1的检测值与设定值不断比较，同时不断地输出信号，控制TV-1。TV-1的开度连续可调。最终使TE-1测量的环境温度保持在设定温度范围内。当盘管后的温度低干某限值时，低温保护开关TS-1切断送电机的电源，从而使新风风阀关闭，防止盘管内的水结冰，胀裂盘管。
How it works:
The air supply temperature control system is composed of temperature sensor TE-1, proportional integral temperature controller TC-1 and electric two-way regulating valve TV-1. TE-1 installed in the air supply pipeline transmits the detected temperature signal to TC-1, and TC-1 continuously compares the detected value of TE-1 with the set value, and continuously outputs the signal to control TV-1. The opening of TV-1 is continuously adjustable. Finally, the ambient temperature measured by TE-1 is kept within the set temperature range. When the temperature behind the coil is low enough to dry a certain limit, the low-temperature protection switch TS-1 cuts off the power supply to the feed motor, thus closing the fresh air valve to prevent the water inside the coil from freezing and expanding the coil.

注意事项
1、驱动器必须予以保护，防止漏水而损坏内部机件和电机。
2、 当修理驱动器时，必须把电源关闭，以防损坏机件或造成漏电引至伤亡。
3、 当接上电源时，切勿试图连接或拆卸电线。
Matters needing attention
1, the drive must be protected to prevent water leakage and damage to the internal parts and motor.
2, when repairing the drive, the power must be turned off to prevent damage to the parts or cause leakage to casualties.
3, when connected to the power supply, do not attempt to connect or remove the wire.
