    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.

  • Page 8: Getting Started

    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.

  • Page 13: Definition Of Terms

    Phason AEC-2 user manual Definition of terms NORMAL OPERATION The AEC-2 is in normal operation when it is displaying the room temperature. When alerts occur, the display will alternately flash the alert message and the room temperature. PROGRAMS Programs consist of Main, Differential, Alerts and General parameters. The AEC-2 has eight programs which can be selected and reprogrammed by the user.

  • Page 14: Adjusting The Aec-2

    Selecting a new operating program As livestock matures, often a change in the room climate is needed. The AEC-2 has eight different programs in memory for eight different climate settings. Any one of the programs can be chosen as the operating program.

  • Page 15: Changing Parameter Settings

    Phason AEC-2 user manual Changing parameter settings Follow the steps below to view and/or edit the parameters in any program. After the parameters have been edited, the changes should be marked in the Blank Program Tables in Appendix D for future reference.
  • Page 16 RETURN again to return to normal operation. NOTE: If the AEC-2 is left displaying a parameter it will revert back to normal operation in 1 minute automatically. If STORE was not pressed the displayed parameter will change back to its previous value.

  • Page 17: Setup Parameters

    It is important that the Configuration decal, included with the AEC-2, is marked correctly and affixed to the side of the AEC-2 when the setup parameters have been programmed. The Configuration decal provides a handy reference when you need to check the mode of operation of the staged outputs.
  • Page 18 AEC-2 user manual Phason Selecting a Parameter to Edit The parameters are stored in a table in memory which is similar to the Factory Program Table on page 22. Any parameter in any program can be edited when memory protection has been turned off. Follow these procedures when editing parameters to become more efficient.

  • Page 19: Reloading The Factory Programs

    When the factory programs are reloaded, all of the existing programs including the setup parameters will be replaced. The AEC-2 will begin with program A as the operating program. The programs and most importantly the setup parameters will need to be reprogrammed for the equipment that is connected. Pay close attention to the configuration of Stages 2 and 3.

  • Page 20: Aec-2 Operation

    Figure 2 shows the operation of each stage of the AEC-2. This particular diagram shows when the stages will turn on and off if the AEC-2 is operating according to the factory settings in program C. Some settings are listed here but the entire factory program table can be found on page 22. The circled numbers correspond to the parameter numbers.

Memory protect must be turned off every time the parameters are edited. The memory protect parameter cannot be stored and is turned on automatically when the control is returned to normal operation.
  • Page 25 Ventilation may be turned OFF when a room is vacant to conserve energy. When it is turned OFF the AEC-2 will display V°FF. DO NOT use this to shut down fans to work on the fans or electrical wiring. Ensure the breakers are turned off.

  • Page 29: Methods Of Use

    Methods of use Programs The AEC-2 has eight programs from which one can be selected as the operating program. To take advantage of the programs, adjust them for different climate settings. They could be used for different kinds of livestock or used at different stages of maturity of the particular livestock. Time is saved by simply changing the program, instead of adjusting every parameter.

    AEC-2 user manual Phason Care and maintenance Moisture will not cause a problem with the control if the proper care is taken in installation. The control's enclosure is made of fire retardant plastic and is sealed with a rubber gasket. The sensor entry is sealed with a liquid tight cable connector.

  • Page 33: Power Factor Correction

    Phason AEC-2 user manual Power factor correction Adjusting the P-Band to correct for a particular power factor may improve your ventilation system's performance. Power factor correction is generally unnecessary and there is no danger of damage being done to the control or motor if it is not done. As a result of different power factors between the many makes and models of fan motors, the actual P-Band may be less then the P-Band setting displayed by the control.
