Glad everything worked out for you. Those damn programs can be such a pain sometimes

I have been working with a bms company on the rtu's and their rep had what sounds like the same issue with errors. I would try using the 2.1 version, that is what I have on my laptop and it worked. I...

The last time I used Trane tech support I called the local guys who then had to register my cell phone numb, name, co name, etc and then I was patched in and got a return call. New system for them in...

Apprentice3,
I had same issue with 14 Intellipac cards and this is what I used to get them programmed.

Tuba,
I had one like that years ago and it turned out to be a spider web right in the oriface. Had to tear it down to find it.

It is a MasterBilt box, chain store to remain unnamed at this time as they are an active customer. The drain heater was good, only went into drain line 1 inch allowing bottom 2 inches of drain to...

Yes that is the drain line. Here is another pic from the same box.

The customer actually asked if the ice build up was ok on a reach in freezer.

Found this while working on another tennant space. Found out later that another one of the guys I work with found this a year earlier and we both notified the tennant.

Found this on a roof last year. Apparently there had been a previous short in the box and this is how it was repaired. Water had actually gotten into distribution panel over time and caused the call...

I had a water cooled unit do the same thing and we were able to get it flushed. However I think with the glycol the whole unit should probably be replaced. In addition the the parts mentioned you...

MOre info needed. Is it short cycling? What are the pressures? Could be many differant things.

You may have a bad inducer motor or like Local 553 said a bad board. Those are 2 speed motors on that unit. I had a 5ton unit several years back that would not fire. All my readings were perfect....

This is a pic from a friend in NYC.

Have had similar issues in the past. I just cut out the molex and put in 1/4 insulated quick connect fittings.

Found these in my truck after cleaning up from a job the other day.

Found these units a few years ago. Glad they were not ours to service.

Have you tried creating your own using a Microsoft excell spreadsheet? That way you can customize it for your specific units. You can also set it up in a computer and keep it as a history for your...

Aircent1,
Your welcome. After rereading the posts I think your issue is with the economizer since you disconnected it. You could need a new module or the dampers and actuator may not be adjusted or...

You mention swapping all 3 boards: RTRM, RTAM and RTOM. All the setpoints are on the RTAM board along with 5 dip switches in the lower left corner of the board. Did you set the dip switches to the...

Does your vav require heat or is it an interior space for cooling only? I have usually see the fan powered boxes used for exterior vav's for cooling and with supplemental heating only. Interior...

What is the model num of the unit? Is it a VAV system as indicated by the pressence of the VFD? Is it controlled as an Occupied/Unoccupied unit? Sound like the unit has a discharge air setpoint that...

I have seen this half a dozen times or more. You should replace the motor. The ignition control board in the unit has the control relay on it to switch between high and low speed.

You wont get a call. It's not 5 deg out with a 30 knot North wind.
