Stromquist & Company sold the first Delphi control systems in the United States. We are pleased to report that the installation of this advanced flamesafeguard system was very easy and our customer is thrilled with how well the system is working. Check out Matt’s demo of the amazing new Honeywell Delphi System!
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
The ML7999 Universal Parallel Positioning Actuator allows for a direct connection to fuel valves and dampers in the boiler system, thereby eliminating mechanical linkages. The ML7999 actuator is designed to operate combustion air dampers, butterfly gas valves, oil modulation valves, and flue gas recirculation systems requiring up to 100 lb-in torque. Each ML7999 has its own ID, so when the R7999 communicates with the ML7999 it is communicating with only the ML7999 chosen for commissioning. The R7999 Controlinks Controller is a microprocessor feature driven controller. The controller must be commissioned by using the ZM7999 software on a PC or laptop using a minimum operating system of Windows 95 or the S7999B System Display.
Commissioning consists of five basic steps:
1. Connect the R7999 to the communications port of your PC and logon to the software with a password. The password prevents the changing of your modulation curve without permission.
2. Specify the base configuration: one or two fuels, with or without FGR.
3. Select system parameters such as Low Fire Hold.
4. Specify the characteristics of the actuators (ML7999) and set the valve/damper end points for each actuator.
5. Create a modulation curve (profile) for each fuel and verify it from maximum to minimum modulation. This curve can have up to 20 points on the curve to allow for smooth money saving transitions from start to stop.

Commissioning of the ML7999 basically consists of location of the minimum and maximum open/closed position of the valve/damper and locking down the actuator.
Working together, the ML7999 and the R7999 allow the burner fuel to air ratio to be adjusted independently to maximize burner efficiency and reduce fuel consumption, which typically pays for the Controlinks system within one year.

Yes, there is an answer! The never ending questions from clients about boiler energy savings, maximizing burner efficiency, reducing emissions and reduced excess air, increased equipment life, increased system reliability, flexibility and increased safety can now be answered.
With ever increasing popularity the Honeywell “Controlinks” fuel air ratio commercial/industrial combustion controls are sweeping the market.
To look at the future we need to understand how boiler efficiency was dealt with in the past. When a boiler is first commissioned at a new site the combustion efficiency is set by the installer using a combustion analyzer and adjusting the single modulating motor with jackshafts and their linkages to the fuel valve and air damper to achieve the best combustion efficiency. This “setup” during startup fixes the air-to-fuel ratio over the firing range of the boiler. Over time environmental and physical changes will reduce this “optimum” setup. Changes in temperature, pressure, and humidity, along with physical wear on the linkages and jackshafts, will alter the fixed air-to-fuel ratio causing increased operating and maintenance costs. The weakest “link” in this system is the linkage so let’s go “LINKAGELESS.”
The basic Honeywell Controlinks system consists of an R7999 Controlinks Controller, Q7999 Universal Subbase, ZM7999 Commissioning Software, and the ML7999 Universal Parallel Positioning Actuator (UPPA).
How the Controlinks system works… Four separate UPPAs (ML7999) replace the single actuator used with mechanical cam and linkage systems, providing independent control of the combustion air damper, the primary fuel, the secondary fuel, and the Flue Gas Recirculation (FGR) damper if used. The UPPAs (ML7999) are controlled by the Controlinks Controller (R7999), which responds to the load, and firing rate demands setup by the installer using a combustion efficiency analyzer throughout the boiler run/load cycle.

Wow, what can I say….I am pleased to announce the first commercial installation of Honeywell’s Delphi system has been completed and is successful!
As a reminder here is what Delphi is: A single NEMA 12 panel and designated the YP900, the Delphi system is a loop and logic based integrated flame safeguard control and fuel-air ratio control with O2 trim for boiler and burner applications.
Included in the completed Delphi panel assembly are a RM7840L1075 burner safety controller with wiring sub base, S7800A Display, Modbus, built in industrial panel PC with touch screen display, ABC900A loop and logic controller for load and O2 trim control. Also included in the YP900 panel is the O2 sensor, mounting accessories and Hall-effect speed sensor with tachometer.
After a couple of small problems that were addressed by Karen Karg, Lisa Holmberg, and Bruce Mickleson at Honeywell FSG, the Delphi panel was commissioned without flaws. When dealing with new complex control systems, like we do here at Stromquist day in and day out, it is a pleasure to have a system such as Honeywell’s Delphi to work with.

This installation was number one of five Delphi systems to be integrated into the boiler systems of a bio-medical division of a worldwide company. First observation from the staff engineer of the client was how impressed he was on how safely the Delphi panel is factory constructed with all relays, fuses, and wiring strips set up so hot wires are not exposed in the panel. He was also impressed on how easily Delphi was to commission using the touch screen menu driven menus without the complexities normally associated with this technology. “Even I can do it” was his exclamation of approval. Time will tell the continuing story of Delphi, but as for now Delphi gets two thumbs up from our client and from me.
I also would like to thank Dave Krause of Honeywell most of all for his experience and help in making this installation of Delphi a success.

For a while now the new buzz word for our clients and manufacturers has been “green” products, which are products that are specifically designed to cause less damage to the environment. In concept we can all agree that thinking green is a good idea.
Does a new green product make your client green? What can we do as distributors to help our clients become green?
When working with a facility manager who wants to become green, the first step is to identify what in the client’s system or processes is not working to peak efficiency. This seems like a no brainer, but it is amazing how many clients want to talk green when valves are leaking, pipes are not properly insulated, boilers are not firing efficiently, or oversized and undersized control valves and equipment are not addressed. As controls experts our integrity is on the line here folks! Take the time to look carefully at the job site and determine what core products you sell that will increase the bottom line energy savings to a client’s facility. Take the time to offer your help and knowledge even on the products you may not sell but may contribute in helping your product be more efficient.
When a client’s system is running properly it is easier for you to show the client where and how that new green product can help them become GREENER, and that my friend is the real color of green.
In the Georgia and Florida areas please contact your Stromquist and Company representative to help you with your energy savings needs.
