Look at the Testo 557/557s.

The 557 doesn't appear to have Bluetooth and it is described as "more accurate", and longer battery life.

The 557s will read down to O PSIG, and below zero in PSI...

I'm curious to know how that slim duct contraption is going to be installed in place of the furnace without it looking like a total abortion, not to mention even working with respect to airflow.

Any ideas on the board failures?

Ugh.

"Good" to "bad" in 2 replies...

:whistle:

PRV?

I have a couple of people looking at the high end stuff, and some of it is due to the lack of availability of the "plain" 2 stage AC/HP equipment.

Anything to look out for when installing one of...

A press tool is pretty much all that's used for darn near everything where I am working at.

Anyone ask for some "long nuts" instead of "rod couplings"?

Try it, it's fun :)

Pretty hard to beat the Hikmicro Pocket 2, even at 2x or 3x the price. This thing pretty much equals Flir cameras sold about 10 years ago at around $7k.

Some of the cheaper ones, typically built...

I haven't seen anything to control static yet. It's either on or off. No VFD's.

OA duct is upstream of return fan. Return seems to be dumped into the unit after the pre heat coils on the big...

Doesn't look like it. Heating and cooling coils are in line with each other.

This one has a separate return fan, tied into the OA ductwork. Neither of those two dampers work. For some reason, the fans are labeled "E", which to me means "exhaust". This one has a branch off of...

As I understand it, the scope of work is for maintenance stuff, not controls overhauls.

At least at this point.

But, I do need to know the basics of how the unit works.

One item on a prior...

I can probably get a picture. I don't know if there is a drawing, or at least a current one.

AHU only. No DX cooling. Chilled and hot water coils.

In that respect, being a ride share driver might be the better deal if it can be classified as a business.

I have used the service (Lyft), and the drivers I have talked with claim to make money...

Insurance would be the biggie.

Plain old car insurance will not cover anything if the vehicle is being used for "ride share" at the time of loss. The ride share companies offer insurance that...

Is the equipment properly sized? Has a load calculation been performed?

High static on Supply or Return? Both?

Type of air filter?

Air conditioner coil? There may be 2 or 3 different...

I just need to learn (enough) about it quickly :)

Interesting how pneumatic stuff is somewhat looked down upon, but it seems to keep working while the computerized stuff all becomes obsolete after...

The heating stuff I have seen so far has pumps that run all of the time.

Cooling seems to have been drained.

That is the main reason I am there.

I am not there to fix anything, yet.

I am there to gather as much information as possible on many air handling units and document not only what is there...

Bunch of pneumatic stuff in a Honeywell box. That's what I have seen so far.

Ah. I was assuming that the whole sensor had to be hit with freeze spray.

Hitting part of it would be much more possible to do.

Thanks, I gather that is what is supposed to happen.

The bigger question is how these things are supposed to be tested, to determine that it works.

Given OA and return dampers that are not...

The equipment is in a hospital, and I am reviewing work done by others that has caused problems.

This is certainly NOT my wheelhouse, but here I am.

So far, most of the actuators/dampers seem...

Stupid question time.

Given an air handling unit, big enough to stand up in, with a freeze stat strung out zig-zagging across equally large copper coils with water or steam inside, how is this...

Yes, the bolt head twisted off. I was using a wrench. No gunk inside the threads.It did not come off easily.

I was not happy.

I figured with the itty bitty bolts and the installation...

The last couple of these have not gone so well.

I did not have much luck getting the last couple of shaft/hub adapters apart from the sheave. The bolts were small, 1/4-20 IIRC. Despite my best...

Good on you for catching it and taking action.

Companies in my area are still looking for the person that's 18 or 19 years old with 30 years of experience. They expect you to hit the ground...

I have the Browning style.

Used it to set the belt tension on a problem piece of equipment, and voila, the belts have stayed tight. Used the belt manufacturer guide for tension and deflection.

I realize that the OP is a year old, but if you want to do TAB, and if you have a real opportunity to switch, do it now as an apprentice.

If you wait, it will be virtually impossible to switch...

I would still need the software, but with the pricing for the adapters, it's not looking like something I'd try to do... at least out of my own pocket.

Contractors want 20 years of experience in an 18 year old body.

My union also offers TAB classes, which is a 40 week investment in a pipe dream. Good for them to generate school training funding...

Ah.

Looks like the AS-CVTPRO-300. I also found a AS-CVTPRO-703.

Both are pretty expensive.

So if I want to plug into the thermostat, a MM-CV101-0 is needed? Plus whatever to connect it to a USB port?

I saw some of those on that big auction site for ~200.00.

That other tool, if I was...

Thanks for the heads up.

I looked at the laptop closely, and what I thought was a serial port is a VGA port.

I am still interested in the software and knowing what adapter works for USB ports.

I am also looking for this software.

I happen to have an old XP laptop that still works.

Any alternatives to the JCI cable part number AS-CBL02-0? It looks like a serial to RJ11 cable. The...

Oddly enough, it seems to be available for Apple.

Has anyone tried using the Testo Smart Probes?

They are compatible with water, just have to do a little bit of math.

I would like to use them to read out across a balancing valve on a boiler...

That Milwaukee tool will cut up to 2" SCH 40 PVC, and it works great as long as the cut is more than about 6" from an end or as long as the pipe is above ~50*F and I find it to be quite difficult to...

That Surge impact driver is awesome. MUCH quieter than a regular impact driver. ACME Tools had them in stock.

If the process was completely open, the applicant would know his or her standing along each step of the way.

The process isn't open, and you do not know. There are plenty of opportunities for...

Then why do they make you (apprentice) choose HVAC or BT when you sign up?

LU 597 tests only once a year, and they just did it. Applications are taken every month- instructions are on their website.

I wouldn't be "scared" of the test, but the study guide will help. If...

Lots of math questions, fractions in particular. No calculator allowed. Lots of picture based questions.

When I went through the interview process, there were several stations with two interviewers: a LU597 employee (as in agent or instructor) and a contractor representative. This was done to cycle...

From your perspective, age may be just a number.

I think you will have a heck of a time getting meaningful employment though.

Good luck.

As I understand it, told by a couple of people that I know that have retired, somehow the union is able to look at previous employment. Permission to search (so to speak) is given by the retiree as...

If you took your union earnings over the last 4 years and readjusted it for full employment, what does it work out to? More or less than what you get now? You can't simply look at the 25% difference...
