Programming the growth curve
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. 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
your PEC Plus 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 starting temperature set point
and a duration. Your PEC Plus automatically calculates the 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.
