For some types of the indoor units, the desired temperature can be controlled in the units of 1°C
or 0.5°C.
- Set the desired temperature lower than the indoor temperature.
- Indoor temperature is displayed on the default screen of the remote controller.
- If the setpoint is set higher than the room temperature, then the unit will remain in the cool
mode but will not begin to cool unit the room temperature exceeds the setpoint.
- If you unit is operating in cooling mode and you press the [On/Off] button the cooling operation
will shut off.
NOTE
!
The compressor starts after 3 minutes and the cold wind comes out.
In the cooling operation, you can select the desired temperature in the range of 18°C ~ 30°C.
The favorable temperature difference between the indoor temperature and the outdoor tem-
perature is 5°C.
What is 3 minute delay function?
After the cooling stops, when the product is started right away, the reason that the cold
