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) 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.
(7) Target – Set the specific target temperature for each of the growout days. The target temperature
ramps between growout days.
(8) 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.
(9) 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.
(10) 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.
(11) Run % – Set the specific minimum vent run % for each of the growout days. The Run % is the
percentage of the Minimum Timer Cycle that the stage will run. This percentage ramps between
growout days.
(12) Level – This setting is used in conjunction with the 8 new stage timer settings. 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.
