o
Dynamic minimum: The controller adjusts the minimum between the cold
and warm set points according to a user-defined differential from the target
temperature.
o
Dynamic maximum: The controller adjusts the maximum between the
maximum cold and max warm set points according to a user-defined
differential from the target temperature.
For more information, refer to Defining Dynamic Ventilation, page 32.
• Ventilation by Weight: The user defines the amount of air to be supplied to the
birds, based on their cumulative weight. For more information, refer to Ventilation
by Weight, page 34.
• Curve: Trio calculates a curve between growth days; the increase between days is
steady. If a curve is not enabled, ventilation increases at the next defined growth
day. For more information, refer to Adding a Curve, page 35.
5.2 Defining the Fans/Ventilation Scheme
Trio enables defining the volume of air supplied using three different methods:
• Basic (required)
• Extra (option)
• Tunnel (option)

ENTILATION
Basic Ventilation provides extremely precise levels of ventilation. There are up to 10 levels
of ventilation (the user can define less than 10 if desired). Each level represents a 10%
increase in ventilation, with Trio precisely adjusting the fan speeds and combinations to
ensure that exactly the right amount of air is being provided. At each level, the user defines
what combination of fans provide the required level of ventilation. Before going to the
next level, fans will provide the maximum amount of air possible at that level.
Depending on the type of fans installed, Basic Ventilation supports on-off fans, variable
fans, and efficiency fans. In addition, fans can run in a cycle (option).
If the Basic Ventilation runs at 100% (the highest amount of air defined) and the
temperature continues to rise, Trio switches to Extra or Tunnel Ventilation (if enabled).
In the illustration below, Basic Ventilation is running at 30% (the defined minimum).
Maximum ventilation is set to 95%. In addition, the ventilation is running at the minimum
and the temperature is low, heating is running at 10%.
• Refer to Defining Basic Ventilation, page 31 for more details.
