A , its characteristic is to use heat sensitive components, partial pressure resistance circuit, RC timing circuit of temperature signals respectively, at the beginning of power grid voltage signal and power supply state samples, through Q6-14, C5 is converted into the corresponding control circuit, composed of positive and negative pulse driving pole changing relay, finally through the concatenated in accused of compressor power supply circuits of JK control of compressor power on and off, can be implemented at the same time of temperature control of compressor under voltage and time delay.If you have any questions about ,you can telephone us at your convenience.
