7.6.2 Growout Curve With Optimum Mode ON
If Optimum Mode is enabled, the grow-out curve screen will expand to the following form. In addition to
the Target Temperature Curve, the table expands to include a Heat Adjustment (HEAT AJST), a Tunnel
Adjustment (TUNNEL AJST), a maximum number of tunnel fans, a minimum runtime percentage, and a
minimum vent level. These allow the grower more automation when it comes to setting up their controller
for the entire grow-out.
(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.
IMPORTANT
: Ramping MUST be enabled for this feature to operate.
At the start of the specific time range “Adjust Between” entered, the Target Temperature will be
adjusted at a rate of 0.5° per minute until it reaches the total adjustment “Target Adjust” entered. The
same applies when it is at the end of the “Adjust Between” period and is returning to the days original
Target Temperature.
For example, this feature can be used to allow drops in temperature during a Feed Cycle. It could also
be used in the summer to insure that the building remains in Tunnel Ventilation well after dark in an
attempt to relieve the stress after a long hot day.
(6)
Max Reduction of Opt%
– The Evolution 3000/3001 can reduce the optimum timers run time when
the outside temperature falls below room temperature. This value is the maximum reduction allowed
for this feature. The maximum is reached when the outside temperature is 40 degrees F below room
temperature. From 0% up to 50% may be selected.
(7)
Day –
This table identifies the specific days of growout that starts the Target Temp. 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.
