The Import AHU command opens the Vallox MagiCAD Selection Tool, which helps the user to select the right Vallox air handling unit and export it to MagiCAD for AutoCAD from the selection tool.
When the Import AHU button is pressed, the user is asked to select the duct connections for the AHU from the current view. The user may select all four AHU related ducts: Supply, extract, outdoor and exhaust but it is also enough to select only the supply and extract ducts. The selection tool will use the air flow and pressure drop values from the ducts for the search criteria of the units in the selection tool. The user accepts the selection with ENTER key.
The user can also continue without selecting the any duct connections by pressing the ESC key.
NOTICE: The usage of the air flow and pressure drop values requires that the ductwork has been balanced with MagiCAD's V&P balancing function. If the user cancels the duct selection or the ductwork is not balanced then the selection has no input values for the search criteria of the units in the selection tool.
Export AHU
Finally when user has done the selection and adjustments for the AHU in the project, the unit can be exported to MagiCAD for AutoCAD.
1. When the unit is exported to MagiCAD for AutoCAD the following UserCode dialog will be shown to user. The user fills the necessary information to dialog and continues with the OK button.
2. Next the Air handling equipment selection dialog will be shown to the user. The user accepts the selection with the OK button.
3. Next the user selects the unit's position in the drawing
4. After the unit's position has been selected the install product dialog is opened where user selects the systems and the installation level for the unit.
The user may install multiple air handling unit instances to the project. The installation is ended with the ESC key.
5. After the unit is installed to the project, the user connects the unit to the ductwork and runs the MagiCAD V&P balancing calculation function.
