I have Refrigeration Basics III.

It has electrical stuff in there as well.

Definitely a must for controls people who come from an IT background and not the mechanical service side.

Find somewhere you can learn on the job.

You will probably have to take a pay cut.

Tuition is never free. But reading books is free, there is tons of free reading about hvac controls on the...

Everything is blue, except FLN, and that is orange with a blue stripe.

After installing delta, and with it's easy to observe color codes for 24vac taps, network, etc, I must say that Johnson's...

I want FAN410.

Never work the JC anymore, but it would be nice to know what I did wrong.

Put a transient voltage surge suppressor on your 24vac power supply?

It couldn't be done when scabbing 24vac from vav electric re-heat though.

you mean, like a guage stuck on the end of a hypo needle?

what do you mean? a 24VDC relay coil? huh?

we use ribmu1c alot.

At what point do you put stuff out for bid?

Ever put the install out for bid and do the programming in-house?

You guys do your own upgrades?

Are you going to buy a VERIS, a FUNCTIONAL DEVICES, or what?

I was thinking of the 1616's.

Delta is where it's at.

I'm an installer, and it's my favorite product to install. My only gripe is no 24VAC outputs on the DSC's. But, you can't have it all....

When I think of an...

I am not here to troll, but I regularly get banned for trolling on electriciantalk dot com.

Myself, and a bunch of other regulars who are frequently banned, have our own forum for trolls at...

This isn't what you do? :cheers: The first thing I dump from the plans is the network riser diagram and the 24v transformer tap runs.

Nah, then I could tee-tap. I'd love to run network with a bunch of tee-taps, instead of having to plan it out so thoroughly.

But I admit, LON sucks because of all those pesky MAC addresses. Who...

bacnet ms/tp can't be tee-tapped, except 6ft of it I guess.

Lon stuff is made to be t-tapped ftt-10 networks.

I hate daisy chaining controllers.

It's more intensive than t-tapping the network. Give me a bacnet over LON protocol!

OTOH, I look into the specs when I estimate, and I noticed peculiar...

That ctrlspecbuilder looks like the drawings that come from the mechanical engineer. They use all the standard instrumentation and plan symbols.

I like the local Alerton dealer's drawings best. Delta's are a little clunky in comparison, but have good info. Johnson doesn't know what drawings are, and Siemens are pretty pathetic. The old...

We should all aspire to be like Bill.

Your cooling water valve is FAIL OPEN spring return? Where do you live? In the south?

What's up with the start/stop on the fan's drive??

Everything I've ever done has been floating.

If you want position, make a feedback input.

Thanks, I'm glad. You probably don't have to worry much, as I've never seen your gear installed in a public building.

The way controls companies pump and dump manpower, there will be no shortage...

Sysint, you can paint your picture however you like, but in this state, if a man is installing DDC controls of any voltage on a prevailing wage job, and he is paid the tel-data rate, then the state...

Glad to see the responses, but the thread kind of got hijacked...

First it got turned into a union thing, then it turned into a 'whose work is it really?' Then I lost track where it went.......
...

I can empathize with owners. A union is in no owner's best interest, no disagreements there. To say otherwise would be bald-faced retarded.

I worked for non-union controls company who has one of...
