SiE-05C Operation Flowcharts
Troubleshooting Inverter K Series 127
∗20 PI control
Controls ON/OFF of the standard compressor and inverter output frequency so that suction
pressure is the optimal value.
∗21 Discharge temperature protection
∗22 Fan control during low temperature protection
If Tc is less than 26.1˚C for 30 continuous seconds, fan speed changes as follows: H + ON / H +
OFF / L + OFF. When Tc becomes greater than 52.4˚C, fan speed returns to H + ON.
∗23 Compressor protection
1. Protection control is triggered when secondary inverter current exceeds set current.
2. Protection control is triggered by discharge temperature.
3. Protection control is triggered when the heating load is small and the saturation temperature
corresponding to suction pressure is high.
4. Protection control is triggered when saturation temperature corresponding to suction pressure is low.
∗24 PI control
Controls ON/OFF of the standard compressor and inverter output frequency so that discharge pressure is
the optimal value.
