    With a built-in low ambient kit or specially designed PCB, outdoor fan speeds can be changed automatically according to condensation temperature. The air conditioner can run a cooling operation even when the outdoor ambient temperature is down to -15°C.
  • Follow Me 
    Temperature sensor built in the remote controller will sense it’s surrounding temperature. The unit will adjust the room temperature more accurately to give you comfort.
