How to Calibrate a Pneumatic Thermostat or T Stat

[@Yourengineeringstandpt]

The thermostat could be filled with oil or like you said, damper diaphragm could have a small pin hole or the heater or valve is sticking just have to pinn point the issue. Love the video thanks for your hard work

[@Mixce33-p9t]

Great Video! I have begun working in pneumatic controls, and have been learning as I go. This video helped to bring the concepts together. Thanks!

[@mattc3385]

Thanks, Ken! I am an apprentice and no one really goes over pneumatics. I am really uncomfortable on pneumatics calls. You really cleared some stuff up for me.

[@dorwinglopez7121]

this is awesome and very informative,thank you for taking the time to make his video.

[@shadcoats28]

GREAT STUFF HERE KEN

[@tcwphalanx3942]

Most excellent video. Very comprehensive. Thank you.

[@sal1514]

Good video with lots of useful info - well done. You mentioned doing a video on velocity controllers, which would be a nice complement to this one, hopefully it's still on your to-do list :)

[@deltafour1212]

Find the spring midrange of your valve Example: spring range is 3 to 6 psi the midrange is 4.5 psi. Measure room temp and set the dial on your T'stat to Room Temp, Insert your pressure gauge calibrate the pressure to 4.5psi. Done

[@ThePharris16]

Good video. How would you calibrate the t-stat if the damper operator spring range doesn't match up with the controller start point and range

[@KenTraining]

Calibrate to the mid point of the controller.

Dont know if you take suggestions, but if you do, it would be great see a video on adjusting a KMC CSC-3011-10 reset volume controller. Thanks! Awesome vids!

[@BenAmoz]

Where is your video on calibrating the velocity controller??

[@KenTraining]

I guess I did not make one yet, Sorry.

Have you ever heard of a company called National Regulator Co. of Chicago? National was the original inventor (some time in the 1850s) of the pneumatic thermostat used for steam radiators.

[@KenTraining]

No, I have never heard of that company.

[@mrvelleful]

Does such a pneumatic system work even if the input (from the compressor regulator) is not stable? Is it important to keep the pressure constant and at exactly 20psi?

[@KenTraining]

you have 2 regulators. One for the compressor maintaining tank pressure and a second regulator maintaining the 20 PSI for the Pneumatic Air.

[@mrvelleful]

@@KenTraining Thanks :) and then, how important is it to keep it at those 20 psi. What if it drifts of to 25psi? Will that affect the output of the thermostat?

[@KenTraining]

Yes, the Thermostat will have a MAX psi rating and you don't want to exceed that.

Hi Ken, how about siemens powermite 599-01088 Pneumatic Valve Actuator for heating zone valve, what spring range to calibrate the thermostat? i didt see it the range on the valve it self

[@Dan78862]

Hi Ken, My question is if its a RA system, Should the velocity Control for heat mode be on Normally Closed or Normally Open setting? I know Cooling should be set on Normally open. This would be for a dual duct system with Heat fans supplying hot air to duct.

[@KenTraining]

I believe it is normally closed. let us know how it works?

[@Dan78862]

Correct. It is normally closed. Thanks for sharing the videos. Doing an awesome job.

hi Kent i work with you at arden realty can you come over to el monte GOOD VIDEO

[@fredrosas2575]

thank you for your time.

[@Losangeles1980]

excellent video, thank you sir!

[@derrickgarcia303]

On DA stat on a N/O valve. The valve would close as pressure increases correct?

[@KenTraining]

yes with a N.O. valve

[@nightone9720]

Thank you

[@davidringer500]

Good info...

[@edgarvalencia3827]

Hey ken shouldn’t your heating duct be N.C on a D.A thermostat, so that would mean that at 0-8 psi the damper should be closed still

[@KenTraining]

yes for a heating duct.

[@nickmiller4544]

please make a video for Siemens Rc 195 receiver controller calibration, thanks.

Hello Ken What is your job description? I love HVAC, but I don't want to be a regular HVAC tech Are you a Stationary Engineer? or a Controls Engineer for HVAC?

[@luisatay3618]

Would you teach at occ

[@KenTraining]

+Luis Atay yes, I would.

[@bass555666777]

I am confused about the hot water valve as it works from 5- 10 psi and also you talk about thermostat from 0-13 psi and then the table is just from 5.5 to 13 it is not clear
