6.2.2 Target Conditions – Optimum Screen With Optimum Mode ON
The target conditions screen shown below represents the display and options when the Optimum Mode is
turned On. Refer to Section 7.1 for turning the Optimum Mode On or Off and Section 7.7.2 for the
Optimum Mode Growout Curve.
(1) Target Temp – Displays the desired temperature of the building for the current growout day.
(2) Adjust – Adjusts the programmed Target Temperature by this amount until set otherwise. The displayed
Target Temp to the left will increase or decrease as this number is adjusted.
(3) Optimum Run% – Displays the minimum vent run % for the current growout day. The Run % is the
percentage of the Minimum Timer Cycle that the stage will run.
(4) Adjust – Adjusts the programmed Optimum Run% by this amount until set otherwise. The displayed Optimum
Run% to the left will increase or decrease as this number is adjusted.
(5) Target Press - This is the desired negative pressure in the building. See Section 7.5.
(6) Tunnel Pressure – Indicates the desired negative pressure in the building while in the Tunnel Mode. See
Section 7.5.
(7) Humidity – The desired target humidity inside the building (Humidity Sensor # 1) is less than this set number.
For every percentage increase in humidity over the set %, the timer percentage will increase.
EXAMPLE:
Target Humidity < 65%
Timer Percentage is set to 20% of 5 minutes.
If Humidity in building is at 70%, the timer percentage will be at 25%.
NOTE: This only affects the variable timer % and Optimum Run %. Min1% and Min2% are unaffected.
(8) Growout Curve Setting – Links to the Optimum Growout Curve Setting screen. Refer to Section 7.7.2.
(9) Current Optimum Base % – The current optimum base run percentage based on the growout curve.
(10) Optimum Timer Active – Displays the current optimum timer active determined by the growout curve.
(11) Maximum Tunnel Fans Allowed – Displays the current maximum number of tunnel fans allowed as
determined by the growout curve.
(12) Tunnel Stage Adjustments – Displays the current calculated tunnel stage adjustments as determined by the
growout curve.
(13) Heat Stage Adjustments – Displays the current calculated heat stage adjustments as determined by the
growout curve.
