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
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.
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 :)
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 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?
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
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?
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.
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
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!
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.
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

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!

this is awesome and very informative,thank you for taking the time to make his video.
Most excellent video. Very comprehensive. Thank you.
GREAT STUFF HERE KEN
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 :)
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
Calibrate to the mid point of the controller.
Thank you
Where is your video on calibrating the velocity controller??
I guess I did not make one yet, Sorry.
thank you for your time.
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?
you have 2 regulators. One for the compressor maintaining tank pressure and a second regulator maintaining the 20 PSI for the Pneumatic Air.
@@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?
Yes, the Thermostat will have a MAX psi rating and you don't want to exceed that.

I believe it is normally closed. let us know how it works?
Correct. It is normally closed. Thanks for sharing the videos. Doing an awesome job.

No, I have never heard of that company.
excellent video, thank you sir!
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
yes for a heating duct.
On DA stat on a N/O valve. The valve would close as pressure increases correct?
yes with a N.O. valve
hi Kent i work with you at arden realty can you come over to el monte GOOD VIDEO
I remenber you bought a Mustang!
@@KenTraining i got a camaro now lol
please make a video for Siemens Rc 195 receiver controller calibration, thanks.
Good info...

it is not clear
Would you teach at occ
+Luis Atay yes, I would.
