Now how did I do that before?

Built-in Operator Training

System – Automated Logic

WebCTRL Operator Training delivered as an add-on!

Getting frustrated with remembering  with a question like, Now how did I do that before? Schedule yourself some no hassle training time.

This add-on includes all the WebCTRL operator training videos for installation on the WebCTRL server.  The videos reside in the add-on’s directory, not in the system, so they won’t be part of a system backup.

To use, simply install the addon and navigate to the /operatortraining path on your server (like “”)

WebCTRL 5.5 released!

WebCTRL v5.5 Released!

System – Automated Logic

We are very excited to announce the release of WebCTRL v5.5 software.

WebCTRL v5.5 includes new innovative features and engineering enhancements to further simplify the industry’s most powerful user interface. Go to Help, and then “What’s new in WebCTRL v5.5” for a complete list. Some highlights are:

Time-Lapse: This new feature makes building and system/equipment diagnostics much easier. A WebCTRL user can choose a calendar date and review from 1 hr to 24 hours of data in just 30 seconds. Time-Lapse can show Graphics, Alarms, or Trends. A video-style toolbar with progress bar allows single step forward/backward, pause, and play

Trend-Clippings: Trends can now be optionally exported in a clipping, enabling projects to be moved between different WebCTRL servers without loss of Historical Trend data.

WebApps in ViewBuilder Graphics: You can now easily add WebApp content to graphics

Increased JAVA Virtual Memory: The default amount of memory that WebCTRL is permitted to use has been increased from 512MB to 1024MB, increasing the speed at which memory intensive tasks are performed

64-Bit Local Access: The 64-bit install now supports local access

Apache Derby Database Support: More robust and stable than the older MS Access, Derby is a cross-platform database supported on both 32/64 bit operating systems. Transfer of files across platforms is achieved through a user-friendly interface

ZS Combo Sensor Support: New control drivers for WebCTRL v5.5 will be released towards the end of this calendar year that support:

An interactive ZS Sensor control on ViewBuilder graphics, allowing adjustment of setpoint and override of an unoccupied state

* New microblocks for the ZS Combo Sensor

* No third-party BACnet point counting

Whats VOC?

Whats VOC?

ALC – Hardware

Humans respirate Volatile Organic Compounds (VOCs) as well as CO2. This new

BAPI sensor is able to measure these VOCs, therefore it is as good an indicator of
space occupancy as a CO2 sensor.
The BAPI Sensor is different from other VOC sensors because it has been
optimized for Demand Controlled Ventilation (DCV). Using a calibration algorithm,
the sensor value is converted to an output with a high correlation to a CO2 level

This lets you use ASHRAE’s occupancy-based VRP schedule to ventilate.

(More info on this correlated output is available on the BAPI control parts website at
Besides from respiration, the sensor picks up VOCs from other sources such as
building materials, perfumes, colognes and furniture off gassing. Using this sensor
to ventilate is a way of acheiving true indoor air quality and not just CO2 dilution.
The unit is available as a VOC sensor alone or as a combination temperature
and humidity sensor. The optional display alternates between the measured
values and is field adjustable between °F or °C. An optional three color LED
indicates “VOC Level” of Good, Fair or Poor.
Features & Options
* VOC Alone or Temperature and Humidity Combination
* Indicates Space Occupancy by Detecting Human-Generated VOCs
* Output is Correlated to a CO2 Value Allowing You to Ventilate Using ASHRAE’s Occupancy-Based VRP Algorithm

Does Demand Controlled Ventilation fit into your Strategy!

So, Hows it been going?


System – Automated Logic

Zone History – So, Hows it been going? Get the question often? Well this may not be about yourself, but your building zones, this WebCTRL add looks to be an excellent tool for developing a building zone strategy or a great maintenance tool.

Zone History helps analyze historical information about zones.  Currently, this is limited to analyzing the amount of time spent in different colors.  We consider this an experiment to help develop some better analysis tools.  We are open to suggestions of other zone information to compare.

This add-on provides a tree of all zones (equipment containing a setpoint microblock).  You can select a zone or an area containing zones.  It will then total the amount of time spent in each color over the specified time range.  The pie chart displayed at the top represents the aggregate data for all the zones beneath the selected location.  Beneath this is a table of all the individual zones sorted by “satisfaction”.  The satisfaction number is the percent of time that the zone was unoccupied (gray) or operational (green).  This is an interesting way to find zones that may be undersized or underserved in some way.  For example, zones that spend a lot of time yellow or orange (without ever going into alarm) will sort towards the top of this list.

This add-on requires WebCTRL 5.5.  One of the features of WebCTRL 5.5 is the ability to automatically trend color information (see System Settings / Scheduled Tasks / Enable Server Trending of Color to enable this).  This add-on will use either these server color trends or any wire trends of color.  Note that the server color trends actually perform better for this application, use of wire trends will often result in colors of “Unknown” when the trends have not yet been reported to the server.

This add-on can also contribute one of these pie charts to a graphics page. WebCTRL 5.5 includes a new “WebApp Content” control in ViewBuilder that can include a pie chart from this add-on calculated using a specified amount of time and a specified location.

Note that retrieving all of this color information and analyzing it can take a good bit of time, especially in large systems.  This add-on will cache this data so that it will be much more efficient if the report is run again on the same day.

Visual Performance Graphics / Viz (ex: chillers)

System – Automated Logic

Viz is a general purpose data visualization tool.  This initial version only supports scatter plots, but later versions will support more graph types.

Viz allows you to add graphs to WebCTRL graphics pages from historical trend data.  Please see the attached help file for detailed instructions. Viz requires the Enterprise license feature.


Viz is now out of beta!

Even though the beta is complete, we would still love to see how you are using this. If you develop some interesting graphs or solve a problem using Viz, please let us know.  We might feature your graph in one of our future write-ups or add it to the set of preview graphs on this page.  If you have a story or graph you can imagine in your system, please let us know

We would very much like feedback on Viz.  Feel free to provide suggestions on the current add-on or ideas for future data visualization features.

System – Automated Logic

Provides simple occupant access to a zone’s setpoints and current temperature through an iPhone.  This only allows access to adjusting setpoint offsets (just like you would on the actual room sensor).  It does not allow access to changing the real underlying setpoints.

Currently in Beta – Requires WebCTRL 5

Need to Chart Temperature?

System – Automated Logic

The Psychrometric Chart graphic allows you to to view a dynamic display of the current wet bulb and dewpoint conditions in a graph showing the relationships of the thermodynamic properties of moist air.

Updated 11/10/2011 with version 2.0 – Added metric values support

Updated 03/04/2011 with version 1.0

Hows the Weather?

Hows your system’s Weather?

System – Automated Logic

How does weather fit into your system? Possible pre-cool or pre-warm up scheduling based on forcast in order to take advantage of building load changes?

Weather retrieves both current weather conditions and forecasts.  This weather information may be displayed on a graphic page or written to a control program for use in control logic.

This version supports two sources of weather information:

  1. The US National Oceanic & Atmospheric Administration (NOAA) National Weather Service (NWS).  This free data is only updated once an hour.  At some weather stations data is not updated overnight.  Please use this one if it satisfies your needs.
  2.  This is a paid service for which ALC is picking up the tab.  It provides data from many more weather stations than NWS (including international stations).  ALC is charged per data query, so please consider this when using this data source.

The different weather services provide different data fields, so you must use the graphic and control program that matches the weather service provider that you choose.  The data you need may determine which weather service you use.

Unique Data

National Weather Service

  • 5 day forecast includes probability of precipitation


  • 5 day forecast does NOT have probability of precipitation
  • Current conditions indludes:
    • Percent Light
    • Feels Like (temperature)
    • Rain Rate
    • Rain Today
    • Rain this Month
    • Rain this Year
    • Wet Bulb Temperature

We would prefer that you use the National Weather Service data if it meets your needs.

When writing data to a control program in WebCTRL 4.1, only parameter microblocks can be updated.  The provided control programs you can download from this page have been modified to work this way, so WebCTRL 4.1 SP1b is fully supported.

See the Documentation tab for configuration instructions.

New Features

Version 2.2.1

  1. Supports HTTP redirects, which some proxies use.
  2. Fixes a problem handling incomplete forecast data from NWS.  If you are using National Weather Service as your weather service and the view page sometimes does not show all days in the forecast (not question marks, just missing data) this bug might be affecting you.  The log file named “addon-weather.txt” might also have text like “Error writing foecast data to CP <path>”.

Version 2.2.0

  1. Version 2.2.0 adds support for HTTP proxies.

Version 2.1.1

  1. This version really does not require the Enterprise license feature.  Version 2.1 was supposed to offer this, but it only half-way solved the issue.  This version fully corrects the issue.
  2. Fixed handling of times to properly use TimeZone information available from the weather services.

Version 2.1

When updating to this version, note that the Standard Equipment and Graphic for NWS and the Standard Graphic for WeatherBug also changed and should be updated.

  1. This add-on no longer requires the Enterprise license feature.  Any WebCTRL system can now use Weather.  In WebCTRL 5.2, the Web Applications page to manage add-ons curently requires the Enterprise license feature.  A forth-coming patch will remove this limitation.  Until then, the add-on can be installed by copying the .war file to the webserver/webapps directory under the WebCTRL installation directory and restarting WebCTRL.
  2. Updated the National Weather Service (NWS) weather source to calculate “feels like” temperatures.  These calculations are based on the formulas provided by NOAA.  A big thanks to Tim Vann for inspiring this feature by implementating similar logic in a control program.  By doing it directly in the add-on, however, we can make the WeatherBug and NWS weather sources more similar.  This change required the associated NWS .view and .equipment files to be updated.
  3. Updated the WeatherBug and NWS views to correctly indicate wind direction.  The “wind arrows” previously pointed in the wind direction, which was confusing since this means they pointed “into” the wind.  They now point in the opposite direction (and the label now reads “from South” to further avoid confusion).

Version 2.0.3

  1. Added an error message when missing the Enterprise Integration license
  2. There are new graphics for 2.0.3 which fix a bug rendering wind directions from the north.

Version 2.0.2

  1. Fixes an important bug.  Previously the Engineer System privilege was required just to view the graphics page.  Now it is only required to configure the weather sources.  Note that this change just affects the .war file, the Equipment and Graphics files were not updated.

Version 2.0

  1. Support for WeatherBug weather service (supports use outside of the US)
  2. Support for control program data in WebCTRL 4.1SP1b
  3. Standard control program supports energy reports with no changes
