In the following example, step 2 has a duration of
10 days. The difference between the starting set
point (86.5°F) and the starting set point for the
next step (85°F) is 1.5°F.
The Supra divides the temperature difference by
the duration 1.5 ÷ 10=0.15 and then automatically
adjusts the set point by 0.15°F each day for 10
days.
You can define two growth curves: Growth Curve A and Growth Curve B. This lets you control
two different areas of your facility with independent set points.
You cannot define two growth curves for the same zone. If all zones are controlled by a single
growth curve, use Growth Curve A.
Growth curve status
There are several options for the growth curve status:

Disabled
– the growth curve is ignored. When enabled, the growth curve starts at day 1.

Enabled
– the growth curve is active for the zones specified.

Suspended
– all set points stay at their current values. The growth curve remains on its current
day until it is enabled again. When enabled, it starts where it left off.

Override
– the growth curve advances one day at a time (in other words, the clock still
advances), but the control uses the
group set point
instead of the growth curve.
When enabled, the control uses the
growth curve set point
for that day. This can cause a sudden
change in temperature if the
group set point
is very different from the
growth curve set point
.
