Munters Element - Ventilation by Weight; How Does Ventilation by Weight Work

4. Define the following parameters:
o
Day: Set growth day
o
Cold Minimum Level: Set minimum ventilation level for when the temperature is below
the heating set point by the amount defined in the Cold Minimum Band.
o
Warm Minimum Level: Set minimum ventilation level for when the temperature is
above the heating set point.
Between the Cold Minimum and Warm Minimum the ventilation curves; see Figure 30: Soft
Minimum Example.
o
Maximum Level: Set the controller's maximum ventilation level starting at that day.

Ventilation by Weight provides air based on the number of animals in the house, their projected weight,
and the outside temperature. After calculating how much air is required based on these factors, Element
determines the required ventilation level to supply the air. Anytime that one of the factors changes,
Element recalculates the ventilation (to prevent changing the ventilation too frequently any change must
be larger than a user-defined amount).
However between two parameters, the Cold Minimum and Warm Minimum, Element ramps the
ventilation. Meaning, Element adjusts ventilation along a curve. If the temperature rises above the
Target Temperature, ventilation increases by levels until it reaches the Maximum Level.
