Description
TOGETHER = When the Minimum Run Time, Mini-
mum Off Time, Restart Temperature, Maximum Off
Time, and Override Temperatures are set in the
Functional Parameter List, the same values will be
used for both Frozen and Perishable setpoints.
SEPARATE = When the Minimum Run Time, Mini-
mum Off Time, Restart Temperature, Maximum Off
Time, and Override Temperatures are set in the
Functional Parameter List, different values may be
entered for Perishable and Frozen setpoints.
YES = Allows access to the IntelliSet menu using the
= key.
NO = Allows access to the IntelliSet menu using the
SELECT key.
OFF = ProductShield Econo is OFF
GO TO START/STOP = Allows unit to be set for and
operate in Continuous Run until ambient tempera-
ture falls within a user-defined range when unit will
go to START/STOP. This allows energy savings
while offering Continuous Run operation protection
when ambient is outside range. Unit will return to
Continuous Run when ambient goes beyond range.
GO TO CONTINUOUS = Allows unit to be set for
and operate in START/STOP until ambient tempera-
ture falls outside a user-defined range when unit will
go to Continuous Run. This provides continuous air
flow and good product protection for extreme ambi-
ent temperatures. Unit will return to START/ STOP
when ambient comes back inside range.
OFF = There is no lower limit for this parameter.
Select the lowest ambient temperature desired to ac-
tivate ProductShield Econo.
If ProductShield Econo is Go To Continuous there is
a minimum 10°F range. Therefore, this parameter's
upper limit is ProductShield Econo Maximum Tem-
perature minus 10°F (5.5°C).
OFF = There is no upper limit for this parameter.
Select the highest ambient temperature desired to
activate ProductShield Econo.
If ProductShield Econo Install is Go To Continuous
there is a minimum 10°F range. Therefore, this pa-
rameter's lower limit is ProductShield Econo Min
Temp plus 10°F (5.5°C).
OFF = Delta-t is not used in determining when the
unit will go into Econo: Go To Start/Stop Mode.
Select the desired delta-t value for activation of
ProductShield Econo. When delta-t is below this set-
ting and within the minimum/maximum range go to
start/stop will be allowed
