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).
Refer to Extra Ventilation, page 127 for more details.

ENTILATION
If enabled, once the temperature reaches the Tunnel Set Point, TRIO turns on the tunnel fans and opens
the tunnel doors. As in Basic Ventilation, you define the fans to be used in each level. However, there is
no curve between levels.
•
Even if Extra Ventilation is enable, TRIO will go straight to tunnel mode if the temperature is
above the Tunnel Set Point (skipping over Extra Ventilation).
•
You can set a differential for each level to ensure that ventilation increases only when required.
In this example, tunnel fans are at level T6.
