TARGET TEMPERATURE DIFFERENTIAL
(a)Enabled = Yes
(b)Target Adjust = +5.0°
(c)Adjust Between 11:00a and 1:00p
(5) Target Temperature Differential – When enabled, this feature will adjust the target temperature
either higher or lower by the selected number of degrees during the selected time of day.
a. Enabled – Select Yes
to enable or No to
disable Target
Temperature
Differential.
b. Target Adjust – The
desired degrees above
or below the Target
Temperature.
c. Adjust Between – The
selected time of day
for which the Target
Temperature
Differential will occur.
(6) Max Reduction of Opt% – The Evolution 4000 can reduce the optimum timers run time when the
outside temperature falls below room temperature. This value is the maximum reduction allowed for
this feature. The maximum is reached when the outside temperature is 40 degrees F below room
temperature. From 0% up to 50% may be selected.
(7) Day –This table identifies the specific days of growout that starts the Target Temp. You are allowed
up to 10 points at which you can change the target at these points. This allows you to keep the same
target for a couple of days and then start ramping down. When the target temperature changes in the
Target column, that target will start the day that is in the Growout day column.
(8) Target – Set the specific target temperature for each of the growout days. The target temperature
ramps between growout days.
(9) Heat Adjust – Set the specific heat adjustment for each of the growout days. A young flock requires
a tightly controlled and heated environment. As the flock grows older, heat is less important. The
Heat Adjust feature ramps between growout days and saves heating costs by allowing the heaters to
run less frequently and only turn on at cooler temperatures as the flock grows older. The Heat Adjust
is the set amount (-x.xº) below the heat stages ON point at which the heat stages will operate. Refer
to the following example charts and figures.
(10) Tunnel Adjust – Set the specific tunnel adjustment for each of the growout days. Older flocks
require a tightly controlled and more cooled environment. As the flock grows older, fan cooling is
more important. The Tunnel Adjust ramps between growout days and is the set amount (-x.xº) above
the tunnel temperature at which the controller will allow tunnel ventilation.
NOTE: The ON point for all cool tunnel stages will also be increased by this amount.
Refer to the following example charts and figures.
(11) Tunnel Fans – The desired maximum number of Tunnel Fans which are allowed to turn On for the
specific growout day. This refers to stages programmed as Cool Negative Tunnel or Cool Tunnel.
(12) Optimum Timers Base % – Set the specific minimum vent base % for each of the growout days.
The Base % is the percentage of the Minimum Timer Cycle that the stage will run. This percentage
ramps between growout days.
(13) Optimum Timers Active – This setting is used in conjunction with the 8 optimum timers. In
addition to each stage being able to operate on a Min1, Min2, VAR, or Cool Timer, they now also
have the option of being programmed to use an Optimum Timer (OPTX). These are labeled as
OPT1, OPT2, …., OPT8. This setting relates to which of these OPTx timers are allowed to operate at
this time. The OPTx timer uses the optimum timer percentage that is calculated by the controller with
the run% being its minimum. This setting allows the user to add additional fans to their minimum
ventilation as the animals age or even change fans completely.
NOTE: The following graphs and figure shows examples of how the EV Optimum Mode would adjust the
target, heat, and tunnel temperatures, minimum run %, and vent level based off of the growout
days and target temperatures.
