After the setting is completed, if you do not press any button in 10s, the system will automatically exit
the current screen and resume displaying the current standby status.
Note:
The one-button drainage function is valid in running or standby status of the entire system. After
entering the one-button drainage function, the outdoor unit sends a forced shutdown instruction, and the
indoor unit shuts down. When the system exits drainage, the forced shutdown instruction is canceled. If
the one-button drainage status is set to on (one-button drainage is enabled), the one-button drainage
code is automatically recovered to OF after 60 minutes.
