Growth curve worksheet
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”.
You can have up to seven steps in a growth curve. Each step has a starting temperature set point
and a duration. The 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.
For more information, read
Programming the growth curve on page 43.
