SETTING USER OPTIONS

The Options item on the View Menu is used to assign a variety of settings influencing program operation. When the Options item is selected, the Options form appears. This form contains two tabs.

A.18.1 General Tab

The General Tab contains the following settings:

• Measurement Units - Choose whether program input data and results are displayed using English

units or SI Metric units.

• Show Tooltips - Tooltips are the small messages that appear when you position the mouse cursor

over toolbar buttons and various other portions of the main program window, or certain input forms. Tooltips will be shown when this box is checked.

• Show Date - When this box is checked, the current date will be shown in the right-hand portion of

the status bar.

• Show Time - When this box is checked, the current time will be shown in the right-hand portion of

A.18.2 Options Tab

The Other Options Tab is divided into three sections. Contents of each section is discussed separately

below.

Validation. Each time you enter a value on an input form, HAP checks the input value to make sure it is

within maximum and minimum limits. If it is not, HAP will inform you of the problem in a number of ways: a beep, highlighting the input item and/or a message box. The settings on this tab govern how problems are communicated. Typically, these settings are adjusted because a user finds the audible signal, the highlighting or the message boxes to be distracting.

• Audible Beep on Validation Error - When this box is checked, HAP will beep when a problem

with an input value is found. When the box is not checked, there will be no audible signal when a problem is found.

• Set Background Color to Red On Validation Error - When this box is checked, HAP will display

the input item which exceeds maximum or minimum limits with a red background. When this box is not checked, the item will not be highlighted in red.

• Always Show Error Message & Require “OK” on Validation Error - When this box is checked,

HAP will display a message box describing the problem. Example: “Value too high (max 32.00)”. When the box is not checked, no message box will appear.”

Please note that any problems identified while you are entering data do not have to be corrected right away. When you press the OK button to save your changes and exit from an input form, HAP rechecks all the data on the form. If problems still exist, HAP will ask you to correct the problems before exiting from the input form.

Operating Mode. Users of HAP have the option of switching the program from full HAP mode to HAP

System Design mode and vice versa. Switching to HAP System Design mode turns off all of the inputs and features for energy analysis. When using the program only for system design work, users may find it more efficient to hide the unneeded energy analysis features from view. Users can switch between operating modes at any time and for any project. For example, if you created a project while in HAP

remain. You will only have to supply the extra energy analysis data to run energy studies. Modes are switched as follows:

• To switch to HAP System Design mode, uncheck the box for "Enable Energy Analysis Features".

• To switch to full HAP mode, check the box for "Enable Energy Analysis Features".

Data Sharing with Electronic Catalog. As a standard feature, HAP always saves input data and system

design calculation results with your project. HAP also has an optional feature for storing equipment selection data for your systems and plants in a format suitable for use by equipment selection software. To turn this feature on, place a check mark in the “Generate and Save Equipment Tags...” check box shown above. To turn this feature off, remove the check mark from the box.

Product selection software requires information organized in terms of “tags”. A “tag” is a single piece of equipment – a rooftop unit, an air handler, an air terminal, etc... Because HAP normally stores data as complete air systems, a special feature is required to extract and reorganize data from air systems so it can be stored as equipment tags and will therefore be suitable for use with equipment selection software. Example: Your project contains a VAV packaged rooftop unit air system. The system serves 25 zones using series fan powered mixing box air terminals. System design calculations have been run for this system. If the “Generate and save equipment tags...” feature is turned on, each time you save this project, HAP will extract information from the system to generate 26 separate tags. One tag will contain data for the packaged rooftop unit. Twenty-five other tags will contain information for the series fan powered mixing box air terminals.

Because generating and saving equipment tags requires extra time, turning this feature ON can sometimes create a delay when saving projects. This is particularly true if your project contains large air systems (serving more than 30-35 zones) or contains a large number of individual air systems. If you notice a significant delay when when saving projects, we recommend turning this feature OFF until it is needed.

A.18.3 Command Buttons

Finally, the form contains three buttons in the lower right-hand corner:

• Press the OK button to exit and apply any changes you’ve made to the settings.

• Press the Cancel button to exit without applying changes you’ve made to the settings.

This appendix describes procedures used to perform various project management tasks. As noted in Chapter 1, a project is a container for data from HAP and other Carrier programs. HAP provides a wide variety of options for managing this data.
