Warm Temperature – Difference Below Heat: Differential below the heat temperature (refer
to Temperature Curve, page 15) that defines outside temperature as Warm in the Soft
Min/Max table. For example, if the Heat Temperature is 78° F, Warm Temp. – Diff Below
Heat is 2.0, than the outside temperature is defined as warm at 76° F.
•
Cold Temperature: Outside temperature (or below) at which Air per Kg/Lb. (Cold) capacity is
reached.
When the outside temperature is between the Warm and Cold Temperature, the flow rate is
calculated at a proportional rate.
•
Air Change: As the temperature rises from the Cold Temperature parameter to the Heat
Temperature (or drops from the Heat Temperature to the Cold Temperature parameter), the
minimal air volume rises/falls proportionally. Air Change defines the minimal change in air
temperature that must takes place to cause a change in the air supply.
•
Fan Cycle Time: The total amount of time that the fans operate while operating under Minimum
Ventilation. During this time, the fans supply the required volume of air at the minimum
ventilation level required. Farm Premium adjusts the minimum ON time and OFF time as
needed. If the fans cannot supply the required volume at a particular level of ventilation, Farm
Premium automatically adjusts the minimum ventilation level.
o
Minimum ON Time in Vent Cycle: The minimum amount of time that the fans operate
during a cycle. Farm Premium adjusts the actual fan time as needed.
o
Minimum OFF Time in Vent Cycle: The minimum amount of time that the fans do not
operate during a cycle. Farm Premium adjusts the actual fan time as needed.
As the temperature rises, the actual Minimum OFF Time decreases until it reaches the minimum time;
only then does the Minimum On Time begin to rise.
NOTE:
If the temperature goes above the Band Temperature, Power Ventilation begins and times are
adjusted accordingly.
•
Air Change By Humidity/CO2%: As the humidity/CO2 levels rise above the levels specified
in Humidity Treatment and CO2 Treatment, the minimal air volume rises proportionally. Air
Change By Humidity/CO2% defines the minimal change in in these levels that must take place
to cause an increase in the air supply.
•
Air Per Weight Curve Mode: By default, Air per Kilo/Lb. has two data points: cold
temperature and warm. If desired, the user can add an additional intermediate data point
which is between the two default points. This point determines the quantity of air to be
distributed when the temperature reaches the midpoint between the cold and warm
temperatures.
