its just a reference number for the controller. CFM is more accurate because there are can be different cfms being moved by 2 different model 15 HP machines

Now I know what the heck you're talking about....I just heard that story.:whistle:

If you mean me, no

The only double time we see is holidays and "new"construction on Sundays.

Source gets all kinds of DT....that's one thing I miss .

I came from non union side 10+ years ago. When I came over , they asked others in the trade about me, I spoke with the people hiring me,and blamo,I became a "journeyman" (whatever that...

I am so used to having high cut ins and outs (being where I'm at for back up) that I forgot there are people in cold climates. 2sac corrected me rightly.

Cut ins he's exactly right. For cut out,...

Yeah, Wally used to like the AAONs now he's all revved up on Lennox units , with Munters dehumid. They don't seem to like "built up" probably because of the size of their stores. Also ,they can...

where I'm at, those are all very common.

Air cooled condenser vs Evap. all the same to me. In the southwest there are a lot of "towers" because of the dryer climate.

Also, compressor racks on...

true...good point

Low pressure controls save lives....Compressor lives

You can get by in setting the Low Pressure control to a higher cut in temp. If you "cut in" at 38*- 40* (converted coil temp estimated) and...

If you're half way decent with your head and tools , you'll always have a job , or will be able to get one anytime in this trade..

There is no season for refrigeration. Yes Summer is technically...

yeah isn't that great?

what a scam

We are just finishing a 134/C02/Glycol store. Started up fairly easy , runs great so far.
Here in SoCal , there are few stores that do not have EMS. And most new stores are getting electronic TXVs...

If your company is making money and the customer is stupid enough to keep calling you guys , then that's what will help keep the economy going in your area.

I'd would tell the guy how much you...

In Bizarro World...he would be right.

Just because people have driven for a long time , does not make them a good driver.

The supermarket refrigeration trade usually weeds out the people who...

I've never seen it be a problem

I think the only time you'll have an issue is if you have to be somewhere else and or it's Friday night

I'd be curious if you recovered some into a tank and did...

I heard you did:grin2:

very common in the southwest. They like to take advantage of the dry climate.

Can be a pain at times....leaks ,scaling access to leaks wear and tear.

go to chat?

ouch..I 've talked to some over there and others have talked to other people..I hear different things....I'd like to get you story.

The "market " game is really changing...hope all works out for you guys...we are in our own battle as I type this.
I hear S.R. is fighting their management and so are we.

We being the Ford to...

Things are creepy in L.A. lately

A ton of bad rumors going around and time will only tell what will happen.

On the Hussmann thing , I heard the case sales are split from the actual...

Is it always that dead? As I see it now, 40 in regular refer , and the "Pros" haven't had a post since yesterday. Regular seems to be where it's at.

Does the E2 still see one AI board as 2? (meaning physical AI #1 =1 and 2)

There are a lot of stupid techs at large companies.... probably a higher ratio at a large company than a small shop.. There is safety in numbers.

When there are so many people, the dumb ones...

I have seen them with a D.I. to an input...I think that's fancy and neato.

I second the sep service.

This thread is the exact reason why I voted no on the "pro forum"

people helping people

This guy wants to learn and some people jump in and help.

Now the guy's curiosity will get him...

Depends on the company you work for.....Some companies won't let tradesmen/apprentices do anything technical. The union rules kinda frown on certain things, I like to show everyone everything because...

yes

Are you in NoCal or SoCal?..I wont talk to northerners:grin2:

I'm just curious..I'm in the union but started as nonunion. "hands on" is the best way AFTER basic knowledge is mastered or at least...

oh this is so exciting!!! who knows the truth??

so true

that MT is fancy... all those boards and whatnot.

best and the worst thing I ever did was go into "the markets"
It's time to put the big boy pants on and do it....it will be fun.
You'll work too much and your friends will think you don't like...

absolute Excellence

The power stuff...I have no Idea..but how the standard rack chilling the C02 rack is running vs what I get out of the C02...it's crazy.
I have to stop talking now...people will know who I am if I...

That video is funny.....but I feel this stuff is the future.
I just spent the last week starting a system up... I have to say that so far I'm impressed.

Yeah I've seen a good amount also.

I believe only 1 for the surge valve. I had it set up with a condition , if I remember correctly. Surge would not feed unless dropleg is above 170# and the...

Just started up a store in which Kysor somehow is using the exact thing as a Tyler Enviroguard. I don'y know how , but piping strategy and everything is the same. The Kysor rep called it The "Kysor...

the graph won't always catch everything

nice...hope it works

Yeah...you're screwed:gah:

If I read this right they are all stopping at once. The E2 showed this?
This unit must have a phase loss monitor , so I would say you're power is ok .

The proof...

So the E2 is alarming on run proof?
I always make the proof alarms at least 30 minutes on those style(scroll with Trax oil) racks.

If the trax oil trips and resets itself, the E2 will run proof...

I've had those crappy enclosed LP controls chatter the heck out of contactors near the bottom of the range , close to cut out. Maybe at low load , the P.I.D. isn't fast enough to stage off machines...

I remember in the late 80's-early 90's when recovering refrigerant became the thing to do. They would always say this could happen. I have never heard of it actually happening though.
I also...

Yeah , I'd double check there isn't a combo board with an AO on the end of it.

Did #3 for a while before I left...will see what happens here for me right now where I'm at.I'm waiting for a C02 start up to unfold here real quick.:munching:

Did my fellow "guest" Mr. knot get...

I explain the pro's and cons of each. The valve plate will fix it ,but the comp may die in 1 week or 1 decade. Let the customer decide his own fate.

Nice explanation

Yes
The P.I.D. will change the way the fan reacts inside that range.
That's the way it stages up/down the speed and intensity of the changes.
If done correctly , an inverter will cruise smooth as...

wow..I haven't heard that one....why won't they (comtrol) die already

if the comm line is cut or not connected to anything else...or shorted ,yes
Usually the 2.3/2.5 +/- is a good indicator that the board is OK . as far as communication goes...but that's not an...
