I have an old c bus system that has a zone manager to handle communications between the e bus and c bus. The zone manager is being removed and a jace has been installed. Do the vav2 controllers...

Good idea. Thank you

Ok. Thanks guys. That's what I was afraid of.

Yes. I don't want it to generate alarms anymore. I looked and couldn't find a setting for this.

I'm having issues with a rtac200 closing the alarm relays #1 and #2 for a "low chilled water temp: unit off" in the colder nights. The temp will typically be around 36 and 38* ENT/leaving when I...

So this may be a common issue? Did this solve the issue?

Ags with remote evap. Trips on "evap pressure low" both circuits on start up when cooler temperatures outside <62°f. Charge is good. Flow is good. It seems like on start up exv closes down and a few...

What software do I need to program/service these controllers. They are set up with a R2 front end.

Rthb215fmc/ u95k with bcu?
I currently have a two chiller plant set up being controlled by bcu. A new control system is being installed to control the chiller plant. We would like to keep the bcu to...

We just picked up an account that has an old school carrier system with comfort system air manager controllers and a comfortVIEW 3.0 front end. I need to replace a controller and need to know how to...

The leak isn't at the discharge. It is in the crotch of the semi-hermetic body. Have you disassembled the compressor before to change the gaskets in the field?

Do you know what number the locktite was that you used?

OK so that's kind of what I figured, that this isn't field serviceable. Thanks for the info.

Its dead center between the motor and the compressor . definitely not the oil filter. Its was blowing bubbles when running.

The compressor on this chiller has a good leak in the area between the motor and compressor of this semi hermetic body. Is this field repairable? I don't think so but I figured I needed to consult...

Ihave an old honeywell system that has a xl15a used as the time keeper and for scheduling. There is a xl15c plant controller that does boiler plant chiller plant and an ahu. I can't figure out how to...

What if we only read points from it and didn't need to write to it at all?

Has anyone done this and left the xl15c and the xl15a in place. I am trying to dumb this down as much as possible. Also what hardware would I need exactly for this system?

We have a customer that has a working and reliable system consisting of 1-xl15, 1-xl15c, 1-rio, 9 vav2, 5-cvahu's. system is configured with lonspec 5.01. They are changing out the old chiller for a...

Is anyone familiar with the circuit board in this unit? Is there a service tool like a navigator to access this board or can it be accessed by carrier "service tool" software. Any insight on this...

Well I have one unt to replace so I guess I will try to find an old computer that runs 98. It wouldn't make sense to spend more on the interface equipment than the hardware needed.

OK so I have 8.02 and it will not work with xp. So I need to start fresh. New version, new adapter? Or find an old computer with 98 on it?

So there is a new version you need for xp. If so does the old cablepro still work or do I need to buy a different one?

where can i find this config.sys file to modify? my card reader took a poop and i am desperate. i have the usb stick and also slta box.

When I open control panel under "lonworks interfaces" the only thing that shows up is the USB Lon device that I only use for rover. Also this is a d630.

My slta box works fine with old lonspec stuff all day long.

Do you know which driver I need and what to add to my config.sys file to use the slta box. My PCMCIA slot doesn't work anymore and I am really stressing out over not being able to use evision.

Can I use a USB to pcmcia cable. Or could I use an old slta box? If so how do I configure evision to see this on com 1?

What is this program that is on my care 7 disk? Is this to replace e vision?

So is it possible to use the usb stick for e vision?

I don't know what tonnage it was doing but it was doing 10.2°

.
Did not check discharge temp. Did check with refractometer, I checked the pressure drop across the evap and there is a chart in the manual that crosses foot of h2o diff to...

Yes I verified the sensors, I checked the water flow with pressure drop. I can't find anything in the manual about flow design with 35% fluid. Or how much this de-rates the chiller.

This chiller is designed to have 239-875 gpm flow. I have 450 and I can go as high as 550 if I turn up the drive. It was set to run at 250 gpm but I turned up the drive when I tested it. It is...

Both circuits run an approach of about 13 degrees loaded. Glycol is ethylene 35%. Is this normal with this concentration on glycol.

Check the input card for those inputs. If those are the only two things on that card I would suspect a bad input card. And check the settings. I have a 200 that is wye delta and it only reads half...

Cheap!

If you need any other bcus or cards that you can't find let me know I have all versions and cards.

Thats great do you have a copy of the software? I don't have a display to troubleshoot.

Does anyone have experience programming this controller or know what software to use and a cable pin-out. Any help would be appreciated. Sales rep says this is a honeywell industrial controller. Used...

I have these if you still need them email me.

Had a ahu controller mp580 that lost its application and program. After I downloaded the application and controller program I couldn't see the i/o's on the expansion modules. My version of rover will...

This morning I removed one gallon oil. Isolated low side and pulled strainer on oil return line that had plenty of trash in it but wasn't plugged. Ran for an hour it loaded fine and unloaded as it...

No I didn't think it was bs, I am used to the old rtaas that have a larger oil separators and over on oil wasn't a big deal. I just figured since it had that much in it from the factory for this...

I looked everywhere and cant find private messenger. My email is there.

Ok I think I just did. If not please let me know.

I will connect with techview in the morning and check and see what the eev position is. Could the extra gallon of oil be enough to coat the tubes in the evaporator and cause the high approach temp? ...
