In a formula profile the profile value is not specified numerically, but instead defined as a mathematical function of weather and/or simulation variables.
Formula profiles are supported by: ApacheSim, ApacheHVAC and MacroFlo.
They may be used in both modulating and absolute profiles.
They are not supported by ApacheCalc, which will set their values to 0 at all times.
You can if you wish type a formula directly into a row of the Daily Profile table in place of a numerical value. In the case of modulating profiles the software provides some assistance with this task: you can click on the Formula button to invoke a utility that creates a formula automatically from control conditions. The Formula button activates the “Modulating formula profile creation” dialog:
To create a formula, use the drop down boxes to select variables, or type into the drop down box to enter a number. The control conditions are interpreted by reading along the dialog from left to right. This utility is best described using examples.
