Controlling Mode
To change the temperature and fan control of the unit. Select from OPTIMIZED or NON-OPTIMIZED.
Optimized: The default Mode for the new Magnum+ for temperature and fan control.
Non-Optimized: The default Mode for the original Magnum for temperature and fan control.
NOTE: Enter setpoint temperature before turning on the Non-Optimized mode. The controller
automatically turns the Non-Optimized mode off when setpoint is changed
Dry Cargo: This mode is intended for dry, not alive and/or evolving cargo. It is only allowed with
setpoints at and above 15C/59F. Changing the setpoint below that will cause the controlling mode to
change to a predefined default mode. The standard default is to Optimized.
With a special customer configuration the default reflects the selected setpoint. For setpoints below
15C/59F the default is Optimized. For setpoints at and above 15C/59F the default is Dry Cargo.
