Have you used the trane BACnet setup tool yet. not sure what RTUs you are working with but all the Intellipaks and Voyagers I've worked on I had to use the Trane BACnet setup tool to program all...

Alerton is a whole other animal. they have specific AV and BV that are microset and other device specific and a whole bunch that were not used on that particular program. Lots of the AV/BV are up to...

That pricing seems kinda odd. i have several laptops and i have CCT14. it was hundreds not thousands to get it per laptop with both FX and Metasys files. I cant even get PCG/PCV series controllers...

if your supervisor is not licensed for more connections could you bring the points into the jace instead. you could create a bacnet ip network on the jace using the other ip port if needed and then...

The trane N4 maxline driver works well. they break it down by points count just like licensing a jace. they have a 500,1000,2000, and unlimited point license. you just have to be sure you have the...

does the trane BCI board have the large square USB port on it. if it's newer it should. you can get get the bacnet set up tool from trane and talk directly to the BCI with a laptop. you might be able...

i have done this conversion multiple times. once you get the gearset out which is pretty easy if i remember correctly. a couple screws and a couple set screws on the actual damper shaft. then you...

for smaller buildings i have used 3/8 for the run between roof and floors. i did a 19 story building and with that one we ended up running 3/4 PVC from the roof to the 1st floor with stubs on every...

I typically utilize the OSS programming at the JACE level. i determine if the site has heating and cooling units or just cooling. programming changes depending on the units. you also have to consider...

for PMs i would just use an existing floorplan and Paint.net to mark it up, save it to a file for other techs to use or print and leave on site. if you want to get fancy i use Visio for my controls...

ive never done what you are looking to do but why are you wanting to change. do you have controls and having issues scaling the 0-5 signal. if you have a BACnet building trane sells a BACnet retrofit...

Remember that UV will also deteriorate the insulation or equipment the light shines on. I use a bipolar needlepoint ion generator. these things work fantastic and surprisingly they eliminate odors....

VAV to reference I.LS02E.PVAV.L1.109:ROOM TEMP
VAV to peer to I.LS02E.PVAV.L2.236:ROOM TEMP

thanks in advance.

tell them its money well spent. they wont have to worry about retro fitting them later. i have done hundreds of the old varicone trane boxes. i just use a titus DECV with no box and a air tight take...

thanks, i will be back on site next week, i will try to get this info then.

I have a site im working on that has insight 3.15 and FLN TECs. Is there an easy way to peer to peer a zone temp from one TEC to another TEC.During remodeling they removed several walls to create an...

I have a building that has Trane Varitrac with the CCPiii panels and tracker 12 software. I am adding a FX80 for some other equipment. My customer understands that converting the CCP to jace and...

To use the balancer option when using PCT during commissioning there is a couple things you must do. after it's enabled you can set the flow to min, max flow settings or damper open or closed etc. if...

JCI uses the following addresses for system use, makes pulling in other brands into a FX jace interesting if they start their addressing at 1.
Address 0 is the supervisor
Address 1 is reserved for...

if your intellipak has the GBAS board then you wont have to re-engineer nothing. what points are you trying to control. most of the time I use a PCG to enable/disable the unit. monitor DA-T, RA-T,...

what you could is get a Johnson controls PCG or PCA general purpose programmable controller and write a program to the specifications you would need. you could easily set up one or more zone sensors...

The way drives are designed they vary not just frequency but voltage below 60 hz. Below 60HZ the motor creates a constant torque value and the HP is varied with the frequency and voltage. After 60hz...

I put an AC in my brother in-laws house 3 years ago. he lives in a cookie cutter neighborhood and his outdoor unit is quieter than the neighbors xl15. I worried for the first year cause working for...

we have lost a few trannys and a rear end on the E250's where I work but the dealer is usually able to get us the van either the same or next day. the dealer keeps a few spares on the shelf, im...

Do you have any light commercial or commercial experience. There is a shortage of good techs on the commercial side. A few years ago when the economy stopped the unions stopped accepting apprentices....

we cant find any good commercial service techs in the seattle area. both 66 and 32 unions have nobody to fill our needs.

I am, but Im a rare breed. I am a HVAC service journeyman for my local. I do controls but my background gives me an advantage. I am trained in building systems, air balancing etc. I was programming...

I have a location im working on that has a single GC1 from round 2000 controlling several zones and a boiler. I am looking for any information or manuals to help
me diagnose the controller. thanks...

hate to bring up old thread but im in a bind. anyone have a download link, email in profile. TIA.

Ok this sounds like some interesting reading. Email should be in profile, TIA.

I would check the schematic on the unit and isolate the dirty filter switch wires from the RTM board and see if there might be a short in the wires between the switch and the RTM.

We have custom grilles made for building exteriors and grilles for spiral duct. Im sure anything can be fabbed up but custom work is not cheap. I would contact a sheet metal fab shop in your area to...

Another consideration you will have to look at is motor minimum speed. VFD certified motors that have blowers built in will have a minimum safe speed in their specs to cool the motor. Usually i see...

Got a magnet. Sticks to its metal with iron in it. No stick to then a metal without iron like aluminin og magnesium.

I use a ToolPak 4 panel. have had it for a couple years and it's held up well. plenty of room for everything. going from a shoulder bag to a back pack has saved me some chiropractic bills. only time...

I got lucky since both my parents have high blood pressure. My dads is extreme and he has no stress at all and for a 80yo man he still gets around and is pretty fit.

This reminds me of when I was a apprentice. My journeyman would say here are my keys open the side door, second rack on your left, third drawer down back left corner bin is what i need. If i did not...

Its about pride in your workmanship. If you cant put your signature on it for everyone to see dont sell it.

Excessive noise at grilles is usually caused by air velocity. Check design cfm and room cfm requirements. If they are in individual offices get square footages and cfms at grilles to compare with...

For the most part you will see equal suction and discharge pressures along with low amp draw at the compressor.

Just thinking out loud here, but wouldn't a two stage condenser still only have one suction line and on liquid line coming out. The staging would be internal to the condenser, either two compressors...

Location Location Location. It all depends on where you live and what the market will maintain. I live in a market where I make the top end of your scale, along with most other commercial techs. but...

Wow, operable window anyone.

The vav's i run into most are fan powered and in both series and parallel configurations. If its not a fan powered box and just a damper with or without reheat its pretty much considered a squeeze...

This has happened to us with some ptacs, new unit showed up flat from factory. Factory sends replacement and says remove serial number and scrap the bad unit. Fixed leak, filled unit and gave to...

it happens, I had a 40hp drive go that way. It was on an intellipak I had shut the unit down with the BMS, then off at the unit itself. hit the 200a disco. do my work and turn back on. 1 of the 4...

the vav box for the most part will mix plenum/space air with supply air and reheat the 50-55 degree supply air. most of the vav systems I work on are supplied with cold air and reheat plenum air when...

I do quite a bit of work downtown and the endless amount of a-holes like to park up against my back bumper. Im in a full sized van and the doors in back leave nice hood scratches. oh and of course...

I use the fieldpiece SDMN5 dual port. works great for negative pressure gas regulators. also use it for general pressure testing of ducts, buildings and wherever I need a inch water column pressure.

if you go with a drive you can mount it in the blower compartment and add a remote panel for the lcd in the electrical cabinet. the factory mounts them in this manner and I have done a few retrofits...
