Features of the AEC-2
The Automatic Environment Control (AEC-2), is a microprocessor based product designed to efficiently
control the environment in livestock buildings. It connects to a variable speed fan, a combination of
secondary fans and heaters and an alarm system. When operating, the AEC-2 measures and displays the
room temperature. While monitoring the temperature it controls the connected ventilation and heating
equipment according to the programmed settings to keep the temperature at the desired point. The
program settings can be adjusted in order to change the turn on points and other parameters of the stages.
The following is a list of the standard features of the AEC-2.
•Digital display of temperature, alerts and settings
•8 programs with pre-programmed factory settings which can be easily changed
•A built-in keyboard to allow easy adjustment of settings
•2 stages of user definable relay contacts to control secondary fans or heaters
•A relay to signal high or low temperature, power interruptions or low line voltage alerts
•Internal memory is retained during power failures
•120/230 VAC operation @ 12.5 amps output for variable speed fan (with RFI noise
suppressor to eliminate radio and T.V. interference)
•3 second full power turn on for variable speed output to minimize fan freeze-up
•Transient protected
•Compact design, 18cm/7" (H) x 23cm/9" (W) x 9.5cm/3.75" (D)
•Non-corrosive, fire retardant enclosure
•2-year warranty
•Extendable sensor

Getting started
Congratulations on the purchase of your new AEC-2 environment control! This manual has been
prepared to help you get the utmost in satisfaction from your AEC-2. It contains detailed information
regarding the installation and operation of the control. The Getting Started section will step you through
the installation and configuration of your AEC-2. The following steps refer to other sections of this user's
guide for additional information. For this reason, it is not necessary to read through the entire document
from front to back, but rather in the order that the information is needed.
CHECKING RATINGS OF EQUIPMENT
STEP 1
Read the AEC-2 ELECTRICAL RATINGS on page 4.
Fill in the EQUIPMENT LIST on page 5.
WARNING: The equipment to be connected to the AEC-2 control must not
draw more current than what the AEC-2 stages are rated for. Use of equipment
that is rated higher than the AEC-2 will result in damage to the control and will
void the warranty.
INSTALLATION
STEP 2
Follow the instructions in Appendix A for installing and wiring the AEC-2
and equipment. Be sure to read the General Warnings section in Appendix
A before installation.
TESTING
STEP 3
Turn to Appendix B and follow the instructions there to test the operation of
the equipment installed and to ensure that it is connected properly.
