Many functions can not be set whilst the indoor unit is running. The installer
should turn OFF the unit before trying to set these functions. If the installer at-
tempts to change the settings whilst the unit is running the main controller will
display a reminder message prompting the installer to stop operation before con-
tinuing. By selecting Yes the unit will cease operation and changes can be made
to the service settings.
If text is displayed in white on a black background CONFIRM button must be
pressed to save this choice.
