7.11.5 Cool Tunnel Properties
The Cool Tunnel Properties
provide for setting override
functions. Take note when setting
the properties. All options must be
true before the stage is allowed to
operate.
For example if all options are set
to Only While, then all options
will have to be true or in the range
before the stage is allowed to
operate. NOTE: Override
parameter settings are "Only
While" and "Always".
(1) Time Override – When set to Only While, the Time Override will allow the stages to operate only
while the time is between the times you set. Otherwise when set to Always, the time will not
affect the stages.
(2) Growout Day Override – During the first days of the growout period, especially during brooding, the
Evolution 4000 can be set to only allow the cool tunnel stages to operate after a specified number
of days in the growout period. When set to Only While, the Growout Day Override will allow the
stages to operate only while the growout day is greater than the day you set. Otherwise when set
to Always, the day of growout will not affect the stages.
(3) Outside Temperature Override - When set to Only While the Outside Temperature Override will
allow the stages to operate only while the outside temperature is greater than the target plus or
minus the desired setting. Otherwise when set to Always the outside temperature will not affect
the stages.
