Plenty Of New Building Controls On Display
Michael Duty, president and chief executive officer of Invisible Service Technicians LLC (www.istmonitor.com), was not complaining about the constant flow of traffic at his booth on the floor of the Orange County Convention Center. Not at all. The more, the merrier. "It's been unbelievable," said Duty. "I couldn't be more pleased."
Passers-by came to view the Invisible Service Technician (IST) monitor, a new remote monitoring and diagnostic device for light commercial and residential heating, cooling, and refrigeration systems. The new product earned Duty and IST the innovation award in the building automation category.
"The IST monitor is one of the first solutions to provide all of the key operating data that a contractor requires to detect and diagnose developing problems before they cause a failure in the customer's equipment," said Duty.
In simple terms, the system consists of a monitor with 10 sensors and six open sensor inputs, mounted on a customer's heating, cooling, or refrigeration equipment and connected to a phone line.
The system monitors multiple operating parameters and immediately notifies the IST data center if a problem is detected. The online data center, in turn, is designed to alert the servicing contractor and provide the technicians with enough operating data to start diagnosing the developing problem before visiting the customer's site.
According to Duty, his device locks in existing customers for contractors. "It offers the contractor the opportunity to detect equipment problems and to contact the customers before they call a competitor." At the same time, Duty insisted the IST monitor helps attract new, increasingly service-oriented customers.
"It adds not only income from the sale of the system, which has been kept low so that it is affordable to customers, but also an income stream from monitoring revenue shared by Invisible Service Technician with contractors," he said. It also increases the efficiency of service technicians. "He or she already knows what the problem is before being dispatched to do the repair."
Internet SavvyElsewhere on the building automation scene, Honeywell (www.honeywell.com) announced the release of a free, Web-based version of its Building Control Workbenchâ„¢, a tool designed to save consulting engineers and other design professionals' time by helping them find Honeywell systems, products, and application data for their building projects "in a matter of seconds."
Like its predecessor, Building Control Workbench 2.0 features "wizards" designed to walk users through a short series of questions related to their projects (application questions about the building systems and how they will be used) and leads them to appropriate offerings. The first version of the software was only available on CD; this latest version is accessible at www.honeywell.com/buildingsolutions.
"It just makes sense that we took this next step," said Michael Taylor, vice president, marketing, Installed Systems. "We are now able to provide updates much faster. When we put the items on a CD, sometimes the information had already changed before we could get the CD out."
The company also introduced its T7350M, a commercial programmable thermostat designed for air-handling units with modulating heating and cooling. The thermostat's features include dehumidification control, easy programmability, and occupancy sensors.
New products Tour Andover Controls (www.tac.com) demonstrated at its booth included the ContinuumÂ® bCX1 router/controller series and TAC VistaÂ® 4.3, an enhanced version of its LonWorksÂ® network-based building management software. The bCX1 features increased power, memory, and reliability, according to Lonnie Laue, director of marketing and sales support for Tour Andover Controls.
"The newest series of controllers offers a lower-cost solution that is also easier to use," said Laue. "In addition, the series offers flash memory to store not only the users' operating system, but also the application code. In the event of a long-term power loss beyond battery life, everything is restored automatically when power is returned."
According to Laue, the company designed the controllers for timesaving setup. "Network configuration is done via a standard Web browser. All models feature removable connections for easier installation and servicing," he said. Three models of the bCX1 are available, including controllers designed for the BACnet network protocol.
In addition, the company's latest enhancements to its TAC Vista "provide important benefits to occasional and remote operators and to building occupants, such as office staff and other nonprofessional users," said Laue.
It includes Web station, a Web-based interface to the TAC Vista Server via Intranet or Internet using a standard Web browser. According to Laue, Web station allows users to access alarms, graphics, trend and time charts, and events whether the users are in the building or on the road, or even if they have limited experience with the program.
At the Loytec (www.loytec.com) booth, the company introduced its L-IP family of integrators designed to link LonWorks networks with Ethernet/IP networks "at an affordable price and with a simple installation." According to the company, L-IP "transparently routes packets from LonWorks networks over Ethernet/IP channels based on the two open standards, ANSI/EIA-709 (LonTalkÂ®) and CEA/EIA-852 (LonTalk over IP)." The company said L-IP can also connect LonWorks networks over the Internet "with a secure and reliable communication path."

Sidebar: New Zoning Opportunities PresentedORLANDO, Fla. - Even though there was not an abundance of new zoning products introduced at the 2005 International Air-Conditioning, Heating, Refrigerating Exposition (AHR Expo), those that were on display were noteworthy.
Emerson Climate Technologies (www.gotoemerson.com) introduced its White-Rodgers ComfortPlusâ„¢ zoning system. According to the company, the system creates separate comfort zones throughout the home using one heating-cooling system.
"Maintaining consistent temperatures throughout the house can be challenging with one system and one centrally located thermostat," said Ron Miles, vice president of sales and marketing - distribution. "The White-Rodgers ComfortPlus Zoning System eliminates these temperature fluctuations by providing conditioned air only where it is needed. In doing so, the zoning system helps homeowners to feel more comfortable and increases the energy efficiency of their home."
The system combines a separate programmable thermostat for as many zones as needed, as well as a central control panel. The system is designed to deliver conditioned air to the specific zone that is calling for it, rather than to areas that are not in use.
Zone-A-Trol (www.zoneatrol.com) made a splash with its new Retro-Roundâ„¢ slip-in round dampers with plug-and-play motors. According to president Richard Foster, the company's insertable zone dampers feature a state-of-the-art motor actuator that allows the installer to just plug in the motor. The DC-powered motor can be wired using standard telephone wire with RJ11 plugs, said Foster. A 25-foot cable is supplied with each damper as is a splitter, allowing multiple dampers (up to 10) to be controlled from a single zone. The motor also has a two-color LED that lights green when the damper is open and red when the damper is closed.
To install, Foster said one has to cut a 1-inch-wide slot the diameter of the damper, lengthwise along the duct. Then slide the damper into the duct and secure with sheet metal screws provided with the damper. Once installed, the damper is wired by plugging in the wire that comes with the damper, back at the plug-and-play module that is required at the zone panel.
Zone-A-Trol also introduced its Mastertrolâ„¢ zoning panels. Its push-in wiring blocks are designed to eliminate the need to screw in each wire. A pushdown button is designed to allow the wire to enter the terminal; release the button and the wire is secured in place, explained Foster.
Arzel Zoning Technology Inc. (www.arzelzoning.com) introduced its modulating bypass control, adjustable from 0.05 to 0.5 inches water column pressure.
Jackson Systems (www.jacksonsystems.com) featured its Retro Damperâ„¢, another round damper for zone control. It also displayed its Zone Oneâ„¢ control damper assembly, designed to solve overheating and overcooling problems. It can be used to control a single room, or by using a number of dampers, zone multiple rooms.
