2 Introduction to the AC-2000 3G
This document describes the AC-2000 3G Precision Mode operation.
Computerized Electronic Controllers such as the AC-2000 3G advance the producer’s ability to grow
high quality eggs by accurately controlling the environment. Instead of struggling with individual
thermostats for heat zones and ventilation, AC-2000 3G brings them all together into one convenient
place with great accuracy. The AC-2000 3G optimizes and precisely applies your equipment and energy
sources to most benefit from the accuracy of your computer and sensors.
The AC-2000 3G coordinates your ventilation equipment in precise levels of ventilation to provide the
optimal fresh air balanced with heating costs. The light and feed clocks provide additional channels for
greater capability. Besides advanced Cooling Pad methods, you benefit from superior stir fan programs
to recover ceiling heat and other features. Precision Mode’s additional features enable you to improve
your profitability significantly.
AC-2000 3G provides a variety of management and history utilities. You can choose from simple
overviews, or fully detailed
by the minute
records of minimum, maximum and average temperatures for
each individual sensor. The unique Table of Events records the moment of every significant action taken
by the AC-2000 3G and, optionally, its operator.

YCLE HEATERS | SET DEFINITIONS
Heat Cycle means providing heat in conjunction with the ventilation system during minimum ventilation
cycles, using heaters and fans connected to relays. When enabled, heaters operate during the fans’
cycle off time (as defined in the Levels of Ventilation Cycle Timer On and Off parameters). How does it
work?
Between the Heat Temperature and the differential temperature, heaters do not operate. When the
temperature goes below the Heat Off temperature minus the Low Heat Differential:
•
Heaters begin to operate when the exhaust or tunnel fans are off. Heaters operate for the
Minimum On Time.
•
If the temperature continues to drop, heaters operate for longer periods of time, up to the
Maximum On Time (defined in Levels of Ventilation).
•
AC-2000 3G automatically generates a curve.
In this example:
•
Temperature Curve Heat Off is 78°.
•
Low Heat Differential is 1°.
•
High Heat Differential is 8°.
•
Minimum On time is 30 seconds.
•
Cycle Off time is 270 seconds.

3.1.4.1 Linear Heat
When Linear Mode is enabled:
•
Between the Heat Temperature and the Target temperature, heaters do not operate (meaning,
the output voltage is 0).
•
Between the Heat Temperature and the Low Difference Below Heat, heaters operate at the
minimum voltage output.
•
If the temperature continues to drop, the voltage output increases until it reaches the maximum
voltage output at the High Difference below Heat.
In this example:
•
Target Temperature is 80°
•
Temperature Curve Heat Off is 78°.
•
Low Heat Differential is 1°.
•
High Heat Differential is 8°.
o
If the temperature is between 77° to 78°, the output voltage is the minimum voltage
defined in Installation > Analog Output (1 volt in this example).
o
If the temperature continues to drop, the output voltage increases until it reaches the
maximum voltage defined in Installation > Analog Output. Output increases or

Proportional Heat works in manner similar to Linear Mode. The difference is that Proportional Heat
features a delay time.
•
When the temperature falls below the user-defined point, the heaters begin operating at their
minimum output.
•
After the response time passes, AC-2000 3G checks the temperature. If it is still below the
defined point, AC-2000 3G increases the voltage by a certain amount (this amount of the
increase cannot be changed).
•
After the response time passes, the process is repeated until heaters operate at their maximum

3.2 Introduction to Humidity, Ammonia, and CO2 Treatment
AC-2000 3G provides various options to controlling the humidity, CO2, and ammonia levels.
•
None: No treatment is provided.
•
Level: Ventilation levels increase for a designated amount of time.
•
Tunnel or exhaust fan: A designated fan turns on for a designated amount of time. The amount
of air blown into the house is greater than that provided by an increase in ventilation level.
•
Increase in air / weight: The total amount of air that fans need to provide increases by a user
defined amount. Fan stay on until CO2, humidity, or ammonia levels fall to their defined levels.
This option is only available when using Minimum Ventilation by Weight.
•
Humidity treatment by heat: In cold air situations, heaters can be turned on to lower the
relative humidity.
If there is a contradiction between CO2, humidity, and ammonia treatments:
•
Ammonia treatment has priority over CO2 treatment.
•
C02 treatment has priority over humidity treatment.
•
Increase in air / weight has priority over other treatments.
•
Humidity treatment by heat takes priority over increasing the ventilation.
3.3 Humidity Treatment
Humidity treatment forces an increase in ventilation level when the humidity is too high. It holds the
increase for ‘Duration Seconds’, and checks back after ‘Interval Minutes’ for another increase. After the
duration, the ventilation level comes back down automatically.

The By Weight option enables controlling the minimum air flow depending on the number of birds, their
weight and the current outside temperature. When using the Weight option, AC-2000 3G takes several
parameters and calculates the air speed, level of ventilation and cycle time needed to supply the required
volume. As opposed to the other ventilation methods, the Weight option is dynamic, with the ventilation
changing according to the current parameters (quantity of air required, weight of birds and number of
birds, outside air temperature). In addition, Ventilation By Weight sends out an alarm if the current
ventilation is below the minimum required level.

to Temperature Curve, page 9) 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. AC-2000 3G adjusts the minimum ON time and OFF time as
needed. If the fans cannot supply the required volume at a particular level of ventilation, the
controller 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. The controller 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. The controller 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/Ammon%: As the humidity, CO2, or ammonia levels rise
above the levels specified in Humidity Treatment, CO2 Treatment, or Ammonia Treatment the
minimal air volume rises proportionally. Air Change By Humidity/CO2/Ammon% 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 (computer
defined) 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

NOTE In a three point curve, the intermediate value must be between the cold and warm value in each
line.
3.5.4.2 Min/Max Level By Weight Help | Set Definitions Version 9.19
Version 9.19 has an additional parameter, Medium Temp, which enables setting up a more accurate
temperature curve in Air by Weight. By default, the curve is determined by the Air per Kg/Lb Cold and
Warm Temperatures. Medium Temp adds an additional (user-defined) point to the curve.
To add the Medium Temp point:
1. Configure Air by Weight as shown in By Weight, page 22.
2. Go to Control > Min/Max > Help and configure the parameters (refer to Min/Max Level By
Weight Help | Set Definitions, Version 9.18 and Below, page 24 for details).
3. In the Help screen, define the Air per Weight Curve Mode:
•
Using the number pad keys to define the mode as 2 or 3.
o
If set to 2, the Medium Temp parameter is disabled.
o
If set to 3, define the Medium Temp parameter.
