Wireless technology has advanced so much in the last few years and the acceptance and value of these controls is gaining immeasurably. All phases of the market have now been touched by wireless thermostats, controllers, and sensors including industrial, commercial and domestic applications.
Honeywell has announced they are introducing a series of integrated combustion panels to go along with the awsome Delphi release from last year. These new panels will incorporate Honeywell’s proven combustion technology into complete panels, making equipment upgrades a snap! All panels will be pre-wired, pre-tested, and a built in a certified UL panel shop. Made in the U.S.A.
The initial offering will include: Read More
Gas metering is a big part of what we offer customers. One product that has proven to be very successful is the Honeywell Smart Multivariable (SMV) 
Transmitter. It is an industry leader – there are no others on the market that work as well. It measures the gas pressure & temperature and measures a differential pressure across a primary element. The primary element can be an orifice plate or a Preso Ellipse pitot tube. It creates a differential pressure that we measure and relate to flow (the square root of the pressure drop is proportional to the flow rate). The SMV calculates a corrected flow by accounting for the compressibility of the gas along with the pressure and temperature that exist in the pipe. It is quite an involved calculation that is pre-loaded into the transmitter and set up using a software wizard. Please keep it in mind for gas metering applications – it is an affordable alternative. For under $4000 you can measure big flows accurately with easy installation. Read More
Every two years Tridium, the pioneers of open systems, has a meeting that brings all the vendors of open products together to show all the incredible products that can now communicate via the Niagara software. Every summit I am amazed at how quickly controls and equipment are able to integrate and share information via the same web-based network.
Imagine a convenience store that integrates the HVAC controls, fuel tank monitoring, security, oven management, lighting control, freezer and cooler control and monitoring, and grease trap monitoring. It has been done! And you can monitor and control it all from the web.
The new products and applications blow me away — everything from the beautiful energy monitoring software, ProphetSuite, to the innovative new sedona framework wireless technology of Pervasive Devices, to the network devices of Contemporary Controls and Easy I/O, to energy meters from Onicon and E-Mon, to open controllers from Honeywell, Veris, and Viconics, to the lighting controls of WattStopper — all communicating on the Niagara open framework and all available through Stromquist & Company.
I hope to see you at the 2012 Summit !
Over the years sequencing different stages for compressors, staged electric heat strips, actuators, pumps, and various lighting applications has not been the easiest job for the mechanic. Functional Devices, manufacturers of the famous Relay In a Box (RIB relays), has released the RIBMN24Q4C-PX programmable sequencer to make your job easier.
The RIBMN24Q4C-PX is used to control four integrated 15 amp SPDT relay contacts with one (0-10vdc) analog signal. Power input of this control is 24 VAC/DC. Unlike other models, the RIBMN24Q4C-PX has an on-board digital display to eliminate the need to attach a voltage meter. Just dial up your desired trip voltage and move on to the next relay set point!
Features:
Relay will activate when control signal voltage reaches or exceeds individual relay setpoint
Turn Off is set to 200mV less than setpoint
Factory relay setpoints: Can be changed by installer
Relay 1: 3V » Relay 3: 7V
Relay 2: 5V » Relay 4: 9V
Minimum setpoint: 0.5V
Maximum setpoint: 9.9V
Relay number will flash 3 times when voltage exceeds setpoint
Pressing UP or DN button in normal run mode will display the voltage present on Analog Input
*Sequencer can be piggy-backed, allowing more than 4 relay setpoints if sequencer 1 and sequencer 2 are using the same power control input and input signal source. At this point the relay setpoints on sequencer 2 can be different or the same as sequencer 1. Note: sequencer requires 5va power draw per sequencer from control transformer.
The RIBMN24Q4C-PX is also shipped with a MT212-6 din rail mounting strip.

Eric continues his conversation with Roger Rebennack. In the second part of this two part interview, Roger speaks in more detail about Honeywell’s WEBS AX security offering, what it takes for a HVAC contractor to be successful as a systems integrator, and why a building owner should look to Honeywell’s product offering for all their building automation needs.

In part one of his two part interview, Eric talks to the dynamic Roger Rebennack. Roger is a leader in Honeywell’s national WEBS AX security group. With over thirty years in the business, Roger is well qualified to speak about the rapid changes in access and security, including how to integrate these through open system platforms into building automation control systems.
A couple of weeks ago I attended a CSD-1 meeting in Florida put on by the State Fire Marshall’s Office with presenters from the National Board. CSD-1 is the national standard for controls and safety devices for automatically fired boilers. This standard has been adopted by most states (if not all) and deals with the assembly, installation, maintenance, and operation of controls and safety devices on automatically operated boilers directly fired with gas, gas-oil, or electricity, having input ratings of under 12,500,000 Btu/hr.
While this is not one of the more enjoyable meetings I have attended, it was very informative. If you are working in the boiler trade within your state I would strongly suggest that you attend these meetings when the opportunity presents itself.
Understanding the who, what, when, where, and why of the regulations of boilers within your state will allow you sales opportunities you may not be aware of. Also it is good to know the regulations regarding who can work on these potentially dangerous systems. In most states the adoption of boiler safety laws are voted on by politicians, most of whom may not know the potential dangers of a boiler. It is up to you to guide these folks in the proper direction when it comes to your livelihood.
I had a chance to sit down and talk with Jim Hayman from CGNA (Controls Group North America) a couple of weeks ago at the members meeting in Minneapolis. I just posted my interview with Jim, go to Stromquist Radio, check it out and let me know what you think.
Jim Hayman joined CGNA in March of 2004 as the Director of Business Development and has helped CGNA grow from 27 to 37 Members and over 50 Preferred Vendors.
