2. Run mode:(Tr: inlet air temperature,Ts：the set temperature)
2.1 automatic run mode
The background lighting of the LCD is white
1) cooling only type automatic run mode:
When the system runs under "automatic" mode for the first time, it will determine the operating mode
according to the follows,
Tr≥Ts+3℃ Choose Cooling mode
Tr<Ts-3℃ Choolse Blowing Mode
The system will shift its operating mode between the above mentioned two to changes of the indoor
temperature. If the system is currently under cooling mode, it will switch to blowing mode when
Tr<Ts-3℃; if the system is currently under blowing mode, it will in turn switch to cooling mode
when Tr > Ts+3℃. The switching mode as below,
2) cold/warm type run mode:
When the system runs under "automatic" mode for the first time, it will determine the operating mode
according to the follows,
Tr≥Ts-3℃ Choose Cooling Mode
Tr＜Ts-3℃ Choose Heating Mode
The system will shift its operating mode between the above mentioned two to changes of the indoor
temperature. If the system is currently under cooling mode, the compressor will stop functioning if the
temperature lowers to such a degree that requires so; then it will recheck the temperature 15 minutes
later: it will switch to the heating mode if the temperature is Tr＜Ts-3℃,or it will still stay in cooling
mode(including blowing mode). if the system is currently under heating mode, the compressor will
stop running if the temperatur lowers to such a degree that requires so, then it will recheck teh
temperatur 15 minutes later: it will switch to the cooling mode if the temperature is Tr＞Ts+3℃.
2.2 Cooling run mode: (Tr: inlet air temperature,Ts：the set temperature)
The background lighting of the LCD is blue
Temperature control range : 16℃—30℃
Temperature control precision: ±1℃
Compressor can’t be controlled by temperature sensor within 2 minutes after it starts.
Control character: when Tr> Ts, outdoor fan motor and compressor on, and indoor fan motor run at
fixed wind speed. When Tr < Ts, outdoor fan motor and compressor off, and when Tr > Ts, outdoor fan motor
and compressor are working again.
If Tr=Ts, the indoor fan motor,outdoor fan motor and the compressor’s state will not change.
wind speed control: (the temperature difference is 1℃)
auto: when Tr>=Ts+3℃, the wind speed is high;
when Ts+1℃≤Tr<Ts+3℃, the wind speed is medium.
When Tr<Ts+1℃, the wind speed is low.
When temperature sensor is off, the fan motor runs at low speed.
when the wind speed changes from low to higher, there is no delay, and when it
changes from high to lower, there is a 3-minutes delay before conversion.
Manual operation: When unit is on the wind speed can be set to high, medium, low or automatic as
required (execute instruction 2 seconds later after receiving remote signal)
