7.6 Growout Curve
The Growout Curve is used to adjust the temperatures and/or minimum vent requirements automatically by
the grow-out day. The specific Growout Curve screen features and setting options will depend on whether
the Optimum Mode feature is turned ON or OFF. The Optimum Mode feature is selected by entering
“Program Setup” and then “General Settings”. Refer to Section 7.1.

(1) Number of Points –Select 2
through 10 points.
(2) Ramping – Select On or Off to
enable or disable ramping.
(3) Preheat Target – Target
Temperature for preheating.
(4) Preheat – On or Off. Preheat
allows the controller to run the
target to a higher set target
temperature for preheating the
house.
(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) Point –This table identifies the specific points. 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) Day – The day of growout that starts the set Target Temp.
(8) Target – Set the specific target temperature for each of the growout days.
