Guarded Access is set NO then the unit can also be switched

Selection from the Main Menu as shown later in this section.
Initiating a Manual Defrost Cycle

evaporator coil temperature is less than or equal to 45 F (7 C).
NOTE: If the Rail Alternate feature is set YES defrost is
allowed with an evaporator coil temperature less than or
equal to 55 F (13 C).
