Using Sleep during Off-Timer Function
When using Sleep mode, if the next OFF‑Timer setting less than 8 hours, Sleep mode will remain active until the OFF‑Timer setting.
If the next OFF‑Timer setting more than 8 hours, it will override the OFF‑Timer setting and will turn the system off 8 hours after
engaging Sleep mode.
Auto Mode (SMART)
In Auto Mode (SMART) the system will automatically switch to Cooling, Heating, Dry or Fan Only modes based on the current room
temperature. Air flow direction can be adjusted in any mode.
When the room temperature is 79°F or above, Cooling mode will activate.
When the room temperature is between 73°F and 79°F, Dry mode will activate. Fan Speed will drop to LOW after 3 minutes.
When the room temperature is between 70°F and 73°F, Fan only mode will activate. Fan Speed is automatically set to LOW, but can
be adjusted when between these room temperatures.
When the room temperature is below 70°F, Heating mode will activate. The room temperature is set to 72°F.
Auto Mode ceases when another specific operation mode is selected. If changing between Cooling and Heating modes, the
compressor ceased for operation for 5 minutes.
Cooling only appliance
a. When the room temperature exceeds 79°F, it will be ran in Cool mode, and the temperature is set to 79°F.
b. When the room temperature exceeds 73°F, but not more than 79°F, it will be operated in the Dry mode.
c. When the room temperature is not more than 73°F, it will be operated in the Fan only, the air volume is set to LOW and the fan
speed can be adjusted
Cooling Mode
Outdoor Fan
The outdoor fan’s speeds (except in single speed‑selection motors) can be changed according to outdoor ambient temperatures
demands. When operating at a fixed frequency, the outdoor fan is forced to operate at the highest speed.
Indoor Fan
While in Cooling or Heating modes, the indoor fan speed is controlled by the remote control: High, Medium, Low and Automatic
setting. When in Automatic speed in the Cool mode for the first time, the fan speed will run at Low setting. After that, temperature
and fan speed is selection in Automatic is shown in Fig.109
When the difference between the setpoint temperature and the room temperature is between 5F to 10F, the indoor fan speed
will keep in Medium Speed. When the temperature difference is lower than 5F, Low fan speed will engage. When the temperature
difference is above 10F, High fan speed will engage.
When the difference between the setpoint temperature and the room temperature is between 5F to 10F, the indoor fan speed
will keep in Medium Speed. When the temperature difference is lower than 5F, Low fan speed will engage. When the temperature
