ENTILATION
If enabled, Extra Ventilation acts as a transitional phase. Extra Ventilation operates in
situations where:
•
Basic Ventilation does not provide enough air to lower the temperature to the
Target Temperature
•
The temperature is still below the Tunnel Set Point.
•
Trio only enters Extra Ventilation if the temperature is 0.5⁰ above the Target
Temperature (this is the minimum; you can set the differential to be higher).
•
You can set a differential for each level to ensure that ventilation increases only
when required.
•
Extra Ventilation supports up to 10 levels. As in Basic Ventilation, you define the
fans to be used in each level. However, there is no curve between levels.
In the example below, Extra Ventilation is running at Level 15. The minimum for this growth
day is Level 3 (30%) and the maximum is Level T1 (first tunnel level).
