  • Page 64: Outdoor Unit Control Mode

    OPERATION Outdoor Unit Control Mode Control function Cooling Anti-Freeze Protection The indoor coil sensor functions as real time temperature detector of evaporator. It prevents the indoor unit evaporator temperature becoming too low. If the indoor coil temperature is too low, the compressor will automatically start protection mode. Overload Protection To prevent system overload caused by excessive pressure, the machine will implement real-time detection when outdoor coil temperature is too high during cooling mode or indoor coil temperature is too high during heating mode.

    OPERATION Control Logic Description (1) Outdoor fan and compressor stop. (2) Temperature setting function is disabled, and no setting temperature is displayed. (3) Indoor fan can be set to high/medium/low, but can not be set to auto. Cooling Mode Indoor fan running rules: In cooling mode, indoor fan runs all the time and the speed can be selected as high,(medium), low and auto.
  • Page 66 OPERATION Control Logic Description Heating Mode Indoor fan running rules: The indoor unit fan will not run until the indoor unit heat heat exchanger reches a high enough temperature. This is because the cold air prevention system is operating. After several minutes, the speed can be selected to high, medium, low, or auto.
  • Page 67 OPERATION Control Logic Description Auto Mode This mode can be chosen with remote controller and the setting temperature can be changed between 61°F~86°F(16°C~30) In auto mode, the unit will choose cooling, heating or fan -on ly mode according to T ( T =T1 -Ts).

    COMPONENTS TESTING EEV Stepper Coil Discharge pipe temperature is too high. This means the compressor is over heating and will shut down and lock itself out. The cause for this issue is lack of refrigerant coming back to the compressor to cool the compressor. The main causes of this would be low charge, restriction or issue with the electronic expansion valve (EEV).
