N2 is rs485 but the zone bus has only one +com line and a common shown on the schematic. I assume the "Cable Pro box (AS-CBLPRO-?, eBay?) or the newer Converter Pro box (AS-CVTPRO-?)" converts the...

Fine. Whatever you say. I simply remember more details. Or realize I came across wrong. And seek to correct that. I dont expect anything. I ask only for what is freely given. And I have twice done...

Yes this is what I am studying now while waiting on the wisdom to straighten me out. Bacnet/IP from the Niagara workstation into the Metasys workstation via WAN. Failing that from the Jace's to a JCI...

No they want it the other way around. My opinion was not asked. It's the Metasys they want as the front end. All or most of the other sites are JCI.

Hi GregF
Thanks for the reply. I am not trying to combine field level networks. I did not read your post before replying this morning to the others. I get jumped when I come here. Must be my face....

I am not trying to change vendors. Nor to take someones work. Or bash any company or technology. I already have and have had the responsibility for the system in question. It is not a school but a 5...

Ok. I did not ask how to do it. I knew better. I was just looking for opinions. Guess I got that. I never said it was a good idea. Since when does that matter?

This is a tough one? Or I am just asking the wrong question? I work with so many different types of controls in the last few years. Seems like every property has their own. I have been caring for the...

Hi
I am wondering how one would approach integrating a site with multiple jace 501's with bacnet and lonworks feild devices all connected with an ethernet switch to a pc running R2 and a browser....

Hi guys
I am aware there are a lot of Tracker threads in the archives. But I am also aware of how quickly things change lately. I have a building with about 16 VariTrac ccp's X13650529-01. I say...

Heat mode, Room temp 67, Summit BCU.

Hi guys
Sorry for the delayed response. The minimum cfm idea is not it since I tried using a higher minimum and it did not work. It is on a summit BCU. I dont recall the terminal numbers but there...

Yes I am sure it is not cycling on high limit. The power/signal stops at the board itself. There are no fixed resistors either. I thought of that. Worked before. Dont now. I go back when I have a...

There are no discharge air sensors. On any of them.

Hi
Single duct electric heat VAV. The heat cycles on and off. The setup is identical to others that do not show the problem. Board # is x13690252-07 comm4, Voltage, flow, safteties etc all ok. Any...

A VFD can run more than one motor at the same time.

GT Jets is correct. Assuming the pumps are in parallel they have check valves on the discharges. Either of the pumps would have to produce a pressure differential equal to or greater than the...

service pack? I did not think of that. Had not needed to up till now.

You dont actually get a choice I think. Rover detects the BCU when you attempt to change modes and gives you a choice, Server connected or GTFO.

The Summit panel is less than two years old. I am unsure of the exact version. BMTX is all I remember and dont have my notes right now. I have Rover 6 all buttons active. And what you describe is the...

Well I can usually buy 1 or 2 of almost anything. It is the complete packages and fair pricing and access to support like upgrades that I need.

I had not tried using the BCU network variables. It would be a pain as you say figuring which is which. But I had assumed they would be even more "guarded". I like Trane stuff. Install a lot of it....

Sorry I was referring to Reliable. And I suppose I should not have. I did make a strong effort to purchase their stuff after encountering the MACHII in an AAOn unit the other day. Colorful. But I was...

Hello Dave
Thanks for the reply. "Sometimes bindings when you have a BCU can be tricky." Well yeah I think that is the heart of the problem. I have created the snvt output. And bound it to the vav....

If there are already delaers in your area then you cant buy except through them. And they wont do it. Oh if you will pay them to come to your jobsite and so on maybe. If I could actualy just buy...
