About quiet mode

You can use quiet mode to decrease the sound of the outdoor unit. However, this
also decreases the heating/cooling capacity of the system. There are multiple quiet
mode levels.

The installer can:

▪

Completely deactivate quiet mode

▪

Manually activate a quiet mode level

▪

Enable the user to program a quiet mode schedule

If enabled by the installer, the user can program a quiet mode schedule.

INFORMATION

If the outdoor temperature is below zero, we recommend to NOT use the most quiet
level.

To check if quiet mode is active

is displayed on the home screen, quiet mode is active.
