Programming growth curves
A growth curve is an extension of the group set point concept. The growth curve automatically
adjusts the temperature set points over time to control the temperature in a room or zone. It is
called a
growth curve because it adjusts the set points as the animals grow.
For example, in hog production, newborn piglets require a high temperature for comfort and health.
As they grow older, they need a steadily lower temperature. Using the growth curve, you can have
the Supra automatically adjust the temperatures. For example, start at 76°F for 1 day, drop to 74°F
for 1 day, then to 71°F for 21 days, 68°F for 14 days, and so on.
You can have up to seven steps in a growth curve. Each step has a
start day
and
temperature set
point
. The Supra automatically calculates the
temperature set points
for the days between the steps
and adjusts the set points at midnight each day.
Individual set points
for the variable and fixed stages
are adjusted relative to the growth curve temperature for that particular day. This is an extremely
powerful feature because it lets you put fan and heating strategies in place once, and then adjust
them automatically over time.
