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
T775M models: Modulating with analog outputs of 2-10Vdc or 0-10 Vdc or 4-20 mA or Electronic Series 90. Relay outputs from 0 to 4 SPDT. 2 sensor inputs
T775R models: RESET OPTION.. 0 to 2 analog outputs 0 to 4 SPDT relay outputs. 0-2 floating outputs.
Sensors: update display and controller every 1 second
Accessories:
C7031D2003 5 inch immersion sensor with well
C7030B1009 wall mount room sensor
C7100D1001 12 inch Duct Averaging Temperature Sensor

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
This article is taken from a flyer written by Belimo about four years ago called “The Belimo Code” We thought we would revive the article to help our clients remember or for the newbie’s to learn from. This article will cover most of the Belimo actuators you will see in the field, for the others, give us a call and we will “Break the Code” for you.
The first part of the Belimo code is why Belimo? Belimo is a Swiss company so the name Belimo is derived from its Swiss meaning…
BEraten Consulting
LIfern Delivering
MOntieren Mounting
Now that we have the Belimo name code “cracked” lets breakdown the actuator codes…The first letter of the actuator code is all about TORQUE…
G 360 in-lb G= GIANT
A 180 in-lb A=AWESOME
A 133 in-lb A=AWESOME
N 90 in-lb N=NORMAL
L 35-45 in-lb L=LITTLE
T 18 in-lb T=TINY
The second letter of the actuator code is about MOTOR ACTION…
F=SPRING RETURN (on power failure the motor will return to its normal position)
M=NON-SPRING RETURN (on power failure motor will stay in its current position)
The third letter is about motor speed…note: non-spring return actuators can combine a forth letter to designate MOTOR SPEEDS…
Q=Quickest running (non-spring return)
C=Fast running
A=No Position Feedback (spring return only)
No Letter= Normal Speed
B=Basic
X=Customized
Next will be a set of numbers…These numbers are about POWER SUPPLY…
24=24 VAC/DC
120= 120 VAC
230= 230VAC
After the POWER SUPPLY numbers (stick with me) are the CONTROL letters/numbers…
Blank=On/Off (spring return)
-1= on/off (non-spring return)
-3= Floating Point (spring return)
-3= On/Off, Floating Point (non-spring return)
-3-P5= On/Off, Floating Point with 5Kohm Feedback (non-spring return)
-3-P10= On/Off, Floating Point with 10Kohm Feedback (non-spring return)
-SR= 2-10 VDC
-PC= 0-20 volt (Phasecut)
-MFT= Multi-Function Technology (program what you want)
-MFT95= 0-135ohm
-MFT-20= 6-9 VDC 20 VDC power supply (spring return)
At last we have our last letter which will deal with actuator OPTIONS…
-S=Built in auxiliary switch
-T= Terminal Block
Blank=Cable Version
We have now broken ‘THE BELIMO CODE” until Belimo introduces more actuators, then we may need to add to our code breaking article. If you need Belimo actuators give us a call at Stromquist and Company @ 1-800-241-9471(Atlanta) or at 1-800-638-7828 (Florida)and we will be “Code Breakers” together.

Mark Harris from Belimo is back with and advanced presentation on Belimo fire and smoke damper actuators. Stromquist is a master distributor for Belimo and can help you with all your Belimo needs. For more information on Belimo fire and smoke damper actuators contact your Stromquist controls expert.
A key part of the life safety system in any building is the fire and smoke dampers. When working as designed these dampers help prevent the spread of fire and smoke throughout the building in the event of a fire. The fire dampers usually do not have control actuators and close when a rise in temperature to about 165 degrees causes a fusible link to open, causing the fire damper to close and stop the fire from passing through a barrier. Smoke dampers and combination dampers do have actuators like those made by Belimo.
These smoke and fire damper actuators become an important maintenance consideration because failure to
With energy costs constantly rising and the desire to conserve energy, the need for “green” or sustainable buildings is critical. Due to changes in technology not only is it possible, it is expected on new construction projects and has gotten much easier and affordable to retrofit existing buildings. At the heart of theses changes is the adoption of open communication protocols such as Lon and BacNet by controls manufacturers and open framework and software by companies like Tridium. This combination is leading a change in what is possible for building owners.
So what do you need to know to take advantage of this new technology? Read More
