) How to select the remote controller functions
In the remote controller function selection mode, three functions can be selected and changed. Select and change them as required.
1) Operation mode display selection mode (Automatic mode cool/heat display selection)
When the AUTO operation mode was set by remote controller, the indoor unit is judged from the room temperature and the cooling or heating
operation is performed automatically. In this case, “AUTO” “COOL” or “AUTO” “HEAT” is displayed at the remote controller. However, “AUTO” can be
displayed alone without the “COOL” or “HEAT” display.
2) Room temperature display selection mode (Room temperature display/no display selection)
Normally, the intake temperature is displayed at the remote controller, but setting can be performed so that it is not displayed.
