Half -automatic Operation Mode
Half
-automatic function is based on original automatic function.
a. Cooling & Heating Model Unit
When system is on and operation mode switches to automatic, the system will
determine operation mode based on the difference of current set temperature and room
temperature and will start operation as per mode determined. In the following selective
conditions, Tr represents room temperature and Ts represents set temperature.
Upon initial entry into automatic mode, operation mode is selected as per the
following conditions:
Tr ≥ Ts-3
℃
Cooling mode is selected
Tr
＜
Ts-3
℃
Heating mode is selected
When entering automatic mode, the system can switch between cooling and
heating mode corresponding to change of room temperature: If the unit is currently in
cooling mode, compressor will shut down when temperature falls into compressor off
temperature range. 15 minutes after compressor is off, compressor will perform
temperature check, at which time if Tr
＜
Ts-3
℃
the system will enter heating mode
otherwise it will remain in cooling mode. If the unit is currently in heating mode,
compressor will shut down when temperature rises into compressor off temperature
range. 15 minutes after compressor is off, compressor will perform temperature check, at
which time if Tr
＞
Ts+3
℃
the system will enter cooling mode otherwise it will remain in
heating mode.

*In the first 2 minutes after compressor starts, it is not under the control of
temperature sensor.

When Tr= Ts, the system will remain its original state.
*Wind Speed Control:

When Tr<Ts+1 ℃ , low wind
Temperature sensor is off and air fan is in low wind speed
Manual: High, middle, low and automatic wind may be set as needed when
unit is on. (The unit will act 5s after receiving remote control signal.)
*Compressor Control: Compressor is not under the control of temperature sensor in
the first 2 minutes after it starts and compressor can only restart at least 3 minutes after it
shuts down. There is no 3-minute protection at initial energization. (There are power
cutoff compensation and 3-minute protection features).
