Description
OFF = The unit will operate normally in high and low
speeds.
ON = The unit will operate in high speed when the
ambient air temperature is outside a user defined
range. This provides increased air flow and good
product protection for extreme ambient tempera-
tures. Unit may return to low speed when ambient
comes back within the range.
OFF = There is no lower limit for this parameter.
Select the lower limit of the ambient range desired
for this parameter. Refer to
information on High Air Min. Temp.
OFF = There is no upper limit for this parameter.
Select the upper limit of the ambient range desired
for this parameter. Refer to
information on High Air Max. Temp.
OFF = Delta-t is not used for determining the activa-
tion/de-activation of High Air Delta-T
Select the desired delta-t value for activation of
ProductShield High Air. Refer to
more information on High Air Delta-T.
Select the desired ambient temperature below which
ProductShield Winter will operate (forced Continu-
ous Run operation).
OFF = ProductShield Fresh is turned off.
ON - The FreshProtect value in the system will be
overridden when operating under high ambient con-
ditions. Refer to Section 4.10.3
on FreshProtect.
This Configuration is used to override the FreshPro-
tect Functional Parameter value already in the sys-
tem. The values displayed will depend on the
FreshProtect Functional Parameter setting for this
application. Only the values that allow less tempera-
ture drop will be displayed, available for selection.
For example, if the FreshProtect Functional Param-
eter is set to C, then the ProductShield FreshProtect
overrides displayed for selection will be A & B.
Ambient temperature above which ProductShield
Fresh will be active.
