I have three laptops, mine and one the other two guys, connected the first two maps no problem but the third will not connect.
I can connect to the MAP, login and click agree, then it wants me to...

If you have access to the Navigator site you can download the newest update for it. They also have some training videos on building programs on FX controllers.

This sounds like a Berg chiller, they just have a cover over the chilled water tank that you can lift off and check the glycol level.

I sent you something to your email, hope it helps a little.

Could I get a copy of the program objects also, email is in my profile, Thank you.

Lol, actually that somehow gives me confidence that i'm making the right move.

Thanks, I have heard some of the others say it can give you a slight advantage knowing how the equipment is supposed to work. That does make sense and i'm not new to computers just this level of...

I am in the Phoenix area. Don't take that wrong, i'm not complaining. I remember when I was still learning the service side, i went home plenty of times with my eyes and head hurting. So I look on...

I have been in this industry for thirty years now, in the service side of it mostly. A few months back I took my first course for BACnet MS/TP training. They offered us a small training package that...

Are these still available?

Wow, thanks waterworld, this thread has a lot of information in it!

I see several jobs (some of ours) using Dolpins and had wondered if they really worked as good as claimed. I have much reading...

What is the pressure on the inlet side of the pump? Pres reg valve setting (12psi)? if the pump inlet pressure drops below the vapor point the water will vaporize, no air injection needed.

I don't know about stupid, but one of the first calls I ran back in the early 80's. It was just to do an inspection on a roof top unit. Put up ladder, walked up to unit, saw the wires hanging out of...

Check the solenoid valve for the economizer, I had one that was leaking and kept giving me low discharge superheat alarms. You can close the ball valve in line with it to verify.

Power inrush would be very high, you might want to stagger them.

DuPont™ Suva® 124 is an HCFC retrofit refrigerant for R-114 in some applications, such as centrifugal chillers. It is also used in high ambient cooling applications such as overhead cranes. When...

Carrier 30HXC water cooled, it failed when it was warm out and has been sitting for 2-3 months.

No one can give you any accurate diagnosis without more info. sounds like txv(?) running wide open, but just a guess without more readings.

All electrical failures, maybe a power surge or so the owners are claiming. By the time I went out everything was shut down and first compressor was being removed. So now everyone seems to be...

Sorry I didn't answer your question correctly. Its not low pressure but 134A, refrig has been removed but not sure if it's oil and water or alot of oil and a little water or what. There was no oil in...

Haven't found out yet and there's a discussion going on between sales and the owner so we are on hold right now.

Looking down into chiller barrel that is filled with oil.

How much oil does it take to fill a chiller barrel?:gah:

I agree with second opinion, a pair of fine point, electronics type needle nose.

It's politically incorrect to display a bagged hvac guy in that manner.:grin2:

So was the screen plugged up? just curious since I haven't run into that one.

I might have to try the beef both ways but the one thing remains clear....

beer in one hand!! lol...it has to make it better!

Thanks for the input, I had forgotten about the megaflow kit. I had seen them a couple years ago but the thought vanished like the equity in my house. We have 9 cfm pumps now and 3/8" hoses but...

Hi all, I am new here and was wondering if anyone has any recommendations for a large vaccum pump. We are looking for 20 cfm or bigger 120v-230v that will be used for chillers 100tons and under as...

Cool, ingenuity is in the eye of the beholder. ;)

Does it oscillate also I wonder?

I haven't tried it with Brisket, does it turn out tender? cuz I always heard Brisket was hard to get tender. The rest of the recipe sounds like mine but I use fresh cilantro, is that the same?

I haven't used these ign. modules much but I'm hearing that if you move the 24V wire to TH-W terminal they will work again.

In Phoenix Az.

I re-read my post, forgot to put the " - " in front of .20, I knew what I meant so kept reading it as such.

However reading thru...

My bad, 9-10" WC inlt pressure.

I think he did mean .20" wc, What I was saying is I had 8 units on one main line, only 2 not working. When those two tried to ignite they almost backfired and sputtered and would lockout. It turned...

I had one almost backfiring, 8 units on a roof and only two not working. Found the inlet gas pressure was too low due to bad main line pres. regulator. Inlet gas pressure was only running about 3"wc.

Entech micro processor class is mainly focused around Yorks Codepak and Optiview, Very indepth and an excellent class. You will almost need a hand truck for the book they give you.
