Im in need of quite a few 1 ton and 1.5 ton R22 TXVs with bleed ports for some PTACs. My supplier says sporlan does not make such a valve.

Lol

We are using the BacNet gateway to interface with Tracer Summit. I have been disappointed in the capability of the gateway also. It seems to be quite buggy, and the greatest disappointment is it...

I'm an in house guy at a resort. We have installed 2 of the LG VRF systems ourselves. Overall we have been happy with them, we still have a few unresolved issues on the first system. I guess my...

The LG MultiV systems use 3 pipes from the outdoor unit suction, hot gas and liquid. The 3 pipes go to what LG calls a heat recovery box (HR Box) . In the HR box there are solenoid valves for each...

As controldude said, the only way to add and configure an expansion module on a 581 is by using the Rover software.. Also TRANE graphical programming is a part of rover.

Thanks for the reply, I found a couple other places on the internet stating it is RS485 but I was trying to get a few more opinions.

Our Trane guy told me it was RS232 so we purchases RS232...

Hello everybody,

I'm trying to get a Trane COMM3 link to a RTAA chiller wirelessly. Does anyone have any idea if COMM3 is RS232 or RS485 and what baud rate?

Thanks,

jdwendling, do you have more info on the Emerson stat the only requires two wires like a model number or link.

Thanks,

How much you asking

Has any of you seen or used a 24volt ac uninterpretable power supply? Any manufactures / model numbers.

Thanks,

Sure thing I'll try to remember to get the info tomorrow.

We just got a ethernet card from TRANE for a BMTW, but getting one for the BMTS is getting real hard to do.

I haven't heard anything yet for sure, but I do know Trane is working on the drawings?

Does anyone have manuals in PDF for WorkPlace Pro and WorkPlace Tech I would love to take a look at any documentation.

Our support and service from Trane is the best. They give us access to all...

I pretty sure the salesman is going to say just about anything to get in the door.

The BCU time comes from the Tracer Summit workstation. Is there a computer workstation on site that has Tracer Summit installed.

Everyware is old software. It has been replaced by Trane Rover software which you can buy from Trane for about $1800 if you can get them to sell it to you.

That's pretty cool, Never seen anything like that before.

We have 9 Vogt tube ice machines on site. They are great machines, I love servicing them. If you have any specific questions after you read the manual I can help you out.

I just ordered it.

In harvest the suction pressure is low should be around 80psi, and the discharge pressure is to high should be around 100psi. It looks to me like the hot gas solenoid is sticking and not opening all...

It took me a couple minutes to find the "24 1 5/8=" in the pics, good eyes.

Thanks for the pictures Lash. Keep em coming! I love to see pictures of the larger industrial jobs.

The Honeywell FocusPro 5000 (TH5220) should do what you need. It have individual set points for heating and cooling. Also it can run off of batteries.

Tracer Summit is a long way from free $$$$

I have a Trane CPL manual in acrobat format. If you would like it I could email it to you. Send my your email address, mine is in my profile.

Those stats are a pain to get off the wall. The trick is using both hands put your thumbs under the stat on the tabs push down on the top of the stat and pull out on the bottom.

Hope that helps.

Not really LonTalk related, but

On these RTUs on the Reliatel control is there an input for occupancy? Of better yet is there a document that shows the pinout on the RTRM terminal strip.

Thanks

Hey Guys,
