I like that better than what I made up before - how about Amps, Circuit Protection?
I have done commissioning, and have never run across that. A WAG is A.C. Power?
which would be in watts, volt-amps, or horsepower. any of those missing from the nameplate?

Think of it more, when the air starts moving. Velocity pressure can be measured anywhere in the duct run. though some locations sample more accurately than others.

cost / flexibilty
You are right. the Velocity in that larger duct will be less. Friction losses would be less? I don't know how significant.

Alright, I do not know the formulas. Look at it this way:
If you have a fixed fan blowing into a blocked-off piece of ductwork, the fan power will be down (Amp-draw / electrical current in...

I don't know about Newton, but I have restricted an outside air damper, in order to increase velocity, and therefore turbulence, in the mixing box of a large AHU with stratification issues...

This will be too quick...
Build your own at home. Find something to automate. It sounds expensive, but it doesn't have to be. There are take-outs around that are not obsolete.
You can't ride the Incline.
Seriously, is MS/TP BACnet?, American Automatrix PUP? Arcnet? Something to do with a social networking website? ur Blackberry?
We aren't seeing it.
We did get an answer to our email, and all of the above is exactly correct. The State table was not used. He used a couple of 'Command Hierarchy's here and there. So, as long as we don't try to view...
Bad doo doo
How did you find them?

licensing? The license was tied to the machine.
It seems to be complaining about a class, though.
do you have the right version installed?
What size UPS are we talking about here - self contained, or the kind with a battery bank?

sorry, if you can't strip it/fixit with teeth and fingernails, you are no good technician.
been there, done that, anyway - also gotten laughed at for soldering stranded wire onto an EOL resistor...
Mesta Electronics is a link.
I am going to shoot from the hip, and disagree about your typical UPS (esp. APC,) - they do not do a battery test, even though they are able to communicate a variety of status info. Look specifically...

What is the norm for Big Box stores - Lowes, Home Depot, Walmart, Sam's Club, Target, Wegmans, Kohls, Staples, JC Pennys, Sears, etc. Do they have their own crew, or hire local contractors?
JCI seems to do some proprietary stuff on the BACnet wire (between it's own). Alerton may choke on that. We have Alerton on a separate UDP port (not 47808 / BAC0). That way Alerton doesn't have to...
I think you might have the right thing, it is actually an RJ-25, which is the same size as an RJ-11, but uses all six positions/conductors.
RJ-45 is eight positions.
show me the diagram, and I...
For others reference, it is a room temp sensor with integral controller.

I doubt this will be of much help, but if I recall, this should be pretty straightforward as a report.
you can do a select with wildcards in a pop-up screen. (drumsticks come to mind, but it is all...

you are welcome, keep at it!
thanks, it is good to see the enthusiasm.
