Watchdog timer output Reset input TL TE TD 7. 4 Sensor circuit This circuit detects the temperature by dividing voltage with resistance and sensor and bringing the voltage value into CPU, using the characteristics of the sensor that resistance varies with different temperatures. TE is for defrosting, while TL is for low ambient cooling operation. [. . . ] If the length of the pipe exceeds 20m, add the refrigerant R-22. Overcharge or undercharge of refrigerant in the outdoor unit will cause malfunction of the compressor. The prescribed amount of the replenishment of the refrigerant is shown in the table above.
