The Honeywell T775 Series stand alone controllers have now been on the market for several years. This diverse controller offers the technician a multitude of installation options on one small package.
This controller that stands 8 inches wide by 4 inches wide can be mounted anywhere within 1000 feet of its sensor location and be purchased as a standard enclosure or a NEMA 4X enclosure.
The T775 has an EEPROM that saves all values entered. The date and time values are retained for 24 hours after power loss. After power loss of more than 24 hours values may need to be reentered.
IMPORTANT: If a high limit set point is entered into a T775 controller this value is IRREVERSIBLE !!
Voltage: 24/120/240 note: cannot be used for DC voltages
Set Point Range: -40 to 248 F
T775A and B models: relay outputs from 1 SPDT to 4 SPDT (no analog outputs). Sensor inputs 1 to 2. Floating outputs 0-to 2

The idea for this article came across my computer in the form of an e-mail sent to me by a fellow employee of Stromquist and Company with an attached photograph.
I know we all strive in our chosen industry to do things right with as much professionalism as our clients will afford us. I also realize at times even the best of service personnel will make installation mistakes. Some of these mistakes are quite humorous, some are quite expensive to fix, and some of these installations could be quite possibly dangerous.
Since the Control Trends website is duty bound to get, you our readers, the best information on new controls, controls installation, and new trends in the control industry would it not be appropriate to also show how not to install a product?
We at Control Trends will not mention anyone’s name or any company name we do this only as an insight to possible installation mistakes and how to avoid these mistakes.
This first installation is quite humorous to me and I call it “The Sunshine State Weather Protector” Read More
Need to replace the older M series Fireye controls? Honeywell has introduced the Honeywell ECHO retrofit solution for replacing the Fireye TFM and UVM FSG controls. The ECHO (R7210M series) controls are a Smart Fit series of controls which allow the contractor to replace the older Fireye M series controls without the extensive wiring required in the past.
The Honeywell ECHO system is based on the standard Honeywell 7800 series controls and all of the standard 7800 series components will work with this control. With the Honeywell ECHO you can now expand the functions that were limited on the Fireye M Series controls to include displays that improve diagnostics and troubleshooting and including the addition of Modbus to connect the equipment to a building automation system.
How easy is the Honeywell ECHO system to install? Simply remove the old Fireye M series control, attach the Echo’s metal conversion frame, and plug in the ECHO control… Add the required purge timing card (if needed), the flame amplifier , and the Flame detector for UV systems…It’s that easy…
While your at it sign up for the Stromquist & Company Boiler Vision Program and save even more !!
So when you need to replace an older Fireye M series control give us a call here at Stromquist and Company and listen to the ECHO….

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
Honeywell has introduced a new HVAC control valve technology that improves temperature control and lowers installation cost by eliminating manual balancing valves. The VRN and VRW series valves provide controlled flow, independent of pressure fluctuations in the system.
When conventional two-way valves in multi-zone systems open or close, the pressure-flow characteristic of the pumps causes an immediate head pressure change to all other valves in the system, resulting in overflow or underflow and the need for manual balancing. With Honeywell’s new VRN and VRW series, one valve integrates the balancing function and control valve function while providing a level of dynamic flow. The dynamic pressure regulator adapts to changing pressures and flows on the supply side of the system, and keeps the flow and energy delivery exactly where specified. In traditional systems, pressure fluctuations could affect the flow across the coils, impacting efficient energy transfer.
Dynamic pressure regulation maintains the required flow rate through the valve by regulating the pressure drop across the control valve seat. The actuator modulates the control valve portion of the valves to the required flow based on heating or cooling load requirements, independent of supply pressure. Flow won’t change until the control system needs to respond to an external change in thermal load or a change in set point. The result is consistent comfort, increased energy efficiency and increased actuator life.

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.
ML7999 Controlinks UPPA actuator
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.
