17-2HVAC PRO User’s GuideKey ConceptsHVAC PRO Software in Pass Through ModeBy running HVAC PRO software in Pass Through mode, you can takeadvantage of network connections to facilitate communicationbetween HVAC PRO software and individual controllers. In PassThrough mode, you can use HVAC PRO software to download ASCconfigurations directly through an N30 Supervisory Controller.In addition, Pass Through mode makes it easier to identify and managecontrollers for common tasks. HVAC PRO software uses some ofM-Tool’s database functions (see Site Book below) to generate lists ofthe controllers connected to a particular N30 Supervisory Controller.In order to perform a task on a given controller, you can simply selectthe controller from a list. For more information on features available inProject Builder, see Project Builder User’s Guide.Site BookSite Book is a program used to define and edit the set of physical orlogical locations that can be connected in an N30 network. Each sitewithin the database has parameters that are needed to establish theconnection. The Site Book configures sites for N30 devices.Site Book installs with either M-Tool or M3/M5 Workstations. Formore information on Site Book, see the Site Book User’s Guide.Pass Through vs. Standard ModeProject Builder provides two options for using HVAC PRO software:Pass Through or Standard mode. Use Pass Through mode whenconnected to the N30 network. Attempting to use Pass Through modewithout an active network connection will result in error messages.Standard mode allows you to perform common HVAC PRO softwaretasks when not connected to the N30 network. Use this mode whencreating or saving configuration files offline for later use.Differences when Using Pass Through ModeAfter starting HVAC PRO software in Pass Through mode, you canuse any of the features available in normal operation except theVMA Balancing Tool (VBT).IMPORTANT: It is not recommended that the PI Loop Tuning(i.e., PRAC) be used on fast loops over the N30network. PRAC requires precise timing that can beaffected by the network response or by runningSite Book.

HVAC PRO User’s Guide17-3When you run HVAC PRO software in Pass Through mode, itrecognizes all N2 devices.Be aware of differences with the following commands: Download Upload Upgrade Commission Controller Information VAV Box Flow Test Collect VAV DiagnosticsThese differences are described in the Detailed Procedures section.Figure 17-1 is an example of the main HVAC PRO screen whilerunning in Pass Through mode. The title bar indicates that you arerunning the software Through Supervisory Controller (Pass Throughmode).Figure 17-1: Main Screen

17-4HVAC PRO User’s GuideVMA DownloadUnlike the VMA1400 Series application download using a direct N2connection, HVAC PRO software running in Pass Through mode fromProject Builder does not allow additional time for the archive processfollowing a download. This will not be a concern unless power isremoved from the devices immediately following a download. Thisinternal archive typically takes 30 seconds. If immediate removal isdesired, perform controller information to verify the device status isoperational. This applies to upgrades running from Project Builder aswell.Download VMA CodeHVAC PRO software can download VMA1400 Series code only whena direct N2 connection is used. Therefore, when HVAC PRO softwareis running in Pass Through mode from Project Builder, this menu itemis unavailable.To update the firmware code in one or more VMA1400 Series deviceson an N30 Supervisory Controller, you must disconnect the N2 fromthe N30 Supervisory Controller. Run HVAC PRO software on a PC(not in Pass Through mode) and connect the PC to the N2. Proceed asdescribed in the Downloading Configurations and VMA Code(LIT-63750404) chapter of this guide.

The dialog box shown in Figure 17-23 appears whileHVAC PRO software scans the NCU for all VMA1400 Seriesdevices and all VAV controllers with diagnostics.Figure 17-23: Collect VAV Diagnostics Scan Dialog BoxNote:The N2 address is logged in the form n-XX, where n is theN2 address and XX is either Single Duct or Dual Duct.Headings with CD and HD in them refer to cold deck andhot deck (for Dual Duct VAVs only). Single duct valuesappear under the CD heading. Use the scroll bar to viewitems that do not appear on the screen.HVAC PRO software logs the diagnostic values in a file namedvavdiag.log in the current directory. It appends this file each time yourun a test. This is a tab-delimited file, suitable for importing intospreadsheets.
