9-2. Protective Functions ■ Cold-air prevention during heating During HEAT operation, the temperature of the indoor heat exchanger is used to control the frequency and lessen the load on the compressor before the protective device is activated. During heating, the fan speed is set to “LL” (very low) or stopped. As the temperature of the indoor heat exchanger rises, the fan speed is changed to the set speed. Indoor heat exchanger temperature (°C) ■ Overload prevention during heating Approx.
■ Defrost detection and release ● ■ CT (Peak current cut-off control) • This function prevents the circuit breaker or fuse from operating to open the circuit. This function works when electrical current has increased due to an increase in the cooling / heating load, or to a decrease in the power supply voltage. In these cases, operation frequency is reduced or operation is interrupted automatically to control the electrical current for operation.
10. TROUBLESHOOTING ■ Precautions before performing inspection or repair ● After checking the self-diagnostics monitor, turn the power OFF before starting inspection or repair. ● High-capacity electrolytic capacitors are used inside the outdoor unit controller (inverter). They retain an electrical charge (charging voltage DC 310 V) even after the power is turned OFF, and some time is required for the charge to dissipate.

.....Applied for only SAP-CRV123 outdoor unit ● ● This outdoor DC fan motor contains an internal control PCB. Therefore, it is not possible to measure the coil resistance, and the following procedure should be used to check the motor. To perform diagnosis, follow the instructions in “Checking the Outdoor Unit” on the previous page and set the outdoor unit to Test Run mode (compressor ON, outdoor fan motor ON).
An inverter A/C operates using pulse signal control and high frequencies. Therefore, it is susceptible to the effects of external noise, and is likely to cause electromagnetic interference with nearby wireless devices. A noise filter is installed for ordinary use, preventing these problems. However, depending on the installation conditions, these effects may still occur. Please pay attention to the points listed below.
11. CHECKING ELECTRICAL COMPONENTS Ground wire 11-1. Measurement of Insulation Resistance ● Clip The insulation is in good condition if the resistance exceeds 1MΩ. 11-1-1. Power supply cord Probe Clamp the grounding wire of power cord with the lead clip of the insulation resistance tester and measure the resistance by placing a probe on either of the two power wires. (Fig. 1) Insulation tester Fig. 1 Terminal plate Then also measure the resistance between the grounding and other power terminals.
