  • Page 32 Cooling Mode/ Dry Mode Model 09/12 If RAT≥SPT, the unit starts cooling operation. In this case, the compressor and outdoor fan will operate and the indoor fan will run at the setting speed. If RAT≤SPT-2, the compressor will stop operation and the outdoor fan will delay 30 seconds to stop. While the indoor fan will run at the setting speed.

  • Page 33: Heating Mode

    Heating Mode Model 09/12 If RAT<SPT+1.5 AND for certain period, the unit will operate in heating mode. The compressor, outdoor fan and 4-way valve will operate and the indoor fan will delay 3min to start at the latest If RAT≥SPT+1.5, the compressor will stop, the outdoor fan will delay 30s to stop and the indoor fan will blow for 60s at setting speed.
  • Page 34 Heating Mode Models 9/12 Residual heat blowing function: During heating, when the stopping condition for the compressor is reached, the compressor and the outdoor fan motor stop running while the louver moves to position L. The indoor fan will stop after running for 60s at setting speed.

  • Page 40 Protections Compressor Over Current Protection: Model 09/12: Compressor will stop when AC current reaches 14.0A for continuously 2.5s. Model 18/22: Compressor will stop when AC current reaches 17.0A for continuously 2.5s. If the unit stops as such protection for 6 times, it can not resume running automatically and display malfunction, it can resume by pressing ON/OFF.
  • Page 41 Protections Deicing Procedure: This protection is for Heat Pump Only This protection is carried out by the cooling cycle (reverse cycle). The defrosting time or outdoor heat exchanger temperature must be more than its setting values when finishing the deicing protection. In the deicing protection, IFAN is forced OFF.
