Manual Mode
Accessing the manual mode from the service menu may be preferable to digging through the inputs and outputs
and configuration parameters. Manual mode also does not require the advanced service password for access. This
control function is best used for unit troubleshooting for temperature and humidity control, compressor control, airflow
control, and mixing box control. See below review of each screen.
