Fresh Air Exchange Open or Closed
If this option is installed and enabled in Guarded Access >
Main Menu Configuration, the Fresh Air Exchange option
allows fresh outside air to be drawn into the trailer and the
interior air to be exhausted by opening the Fresh Air Exchange
door. This feature is beneficial when hauling loads that release
gas as they ripen, such as potatoes. The Fresh Air Exchange
feature is only available with setpoints above 32 F (0 C). The
feature is disabled with setpoints of 32 F (0 C) and below. This
feature may not be available if OptiSet Plus is in use.
The Fresh Air Exchange feature should be used exactly as
specified by the customer.
From the Change Mode menu choose Open Fresh Air
Exchange and press the SELECT Soft Key (Figure 137).
