If you ever wanted to know how to calibrate a pneumatic thermostat you have found the right video. Stromquist & Company’s, Tim Chamblee, calibrates 4 different pneumatic thermostats at the same time.
If you are in Georgia or Florida you can contact one of the control pros at Stromquist & Company to purchase pneumatic controls. If you are in another part of the country one of our affiliates at Controls Group North America can take care of your control needs.
Pneumatic thermostats are still very much in use. Unless you have been around for a while and calibrated one of these devices, they can be a bit time consuming to figure out. The biggest thing to get past is the vocabulary involved. What one vendor calls “proportional band” another calls ” % authority”. Remember these things were state of the art technology when Don Draper and the boys from the TV show Mad Men had three martini lunches and got paid lots of money to make up words to call things.
So if you find yourself having to calibrate a pneumatic thermostat my first tech tip is : DO NOT READ THE INSTRUCTION SHEET. Just remember this video from Jerry Condiff. Jerry is a pneumatic controls trainer, who has calibrated more pneumatic thermostats than the total of all the drinks the MAD Men of the fifties drank not just at lunch put dinner too. Thanks Jerry.
It’s only a lost art if no one shows you how. Come learn about pneumatic controls at the best “hands on” training class at Stromquist & Company. Space is limited so sign up now!

There has been a lot of buzz on Control Trends lately on Cv so I thought I would do my best to explain what Cv is and how does it relate to HVAC systems.
NOTE : I am not attempting to be exact on definitions only practical in field use of the Cv information.

Over the years Control Trends has given you a look at various manufactures of controls and their products. I came across this video the other day that is quite unique in it’s own rite. And you know, it’s time to give Siemens some good old Control Trends Love… We know them… we sell them now let’s look into Siemens a little deeper.
In the HVAC world Siemens supplies Thermostats, Sensors, Controllers, Valves, Damper Actuators, VFDs, Switches and Realys, and so much more. In the future I will be bringing to you (being an old boiler guy) a look at the Siemens controls that deal with the boiler side of our industry. But for now enjoy the “primer” and let’s give Siemens the love they deserve.
I am posting this for Dieter Schill. Dieter is the president and CEO of Millennial Net. I was unfamiliar with Millennial until Dieter made a comment regarding the Controltrends post “Results of Controltrends 2012 Pneumatic Controls Survey“. Because of Dieter’s comments and because Controltrends is interested in all HVAC control products, I asked Dieter if he would like to educate the Controltrends community on the Millennial Net Control offering. Our sponsor Stromquist & Company does not handle Millennial Net; it looks like a very cool and innovative product offering. If you have used these products, PLEASE PLEASE, tell me about them in comments. I am very curious about this product line.
The following is from Dieter:
