o
Curve Points: Define the number of Min-Max levels. Range: 1 – 30. Default: 1
o
Min Max Level Control By: Set this parameter to Basic.
3. Go to Control > Min Max Level.
4. Define the following parameters:
o
Day: Define the growth day at which the ventilation levels change. Range 1 – 10.
Default: 0
o
Minimum Level: Set the controller's minimum ventilation level starting at that day.
o
Maximum Level: Set the controller's maximum ventilation level starting at that day.
NOTE Each day's minimum ventilation level must be lower than the corresponding maximum level.

Soft Minimum ventilation provides ventilation based on the day and the temperature. As the
temperature decreases or rises, the ventilation level changes accordingly. However between two
parameters, the Soft Minimum and Warm Minimum, Element ramps the ventilation. Meaning, Element
adjusts ventilation according to the temperature (to prevent changing the ventilation too frequently any
change must be larger than a user-defined amount).
If the temperatures drop below the heat temperature and later begin to rise, ventilation behavior
depends on which
temperature sensor is being used.
•
When using an outside temperature sensor, the ventilation curves functions when the
temperature increases or decreases. This prevents excess cold air from entering the barn while
allowing for increases to match the rising temperatures.
•
When using an inside temperature sensor, the ventilation curve functions when the
temperature decreases. However if inside temperature increases, the ventilation levels
remain at the lowest level reached. This is done to prevent cold outside air from entering the
barn. When the temperature falls to the heating temperature, only then does the ventilation
increase.
