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 135).
