Have who ever purchased the equipment contact their engineer and have them send you the correct bid docs. Unless you're going to attempt to throw S and see if it sticks.

XL50 is a different animal. Even though in Niagara the folder is named XL10 they have nothing in common. I may be wrong with this statement, Xl50 requires Care and you must have the original Care...
Yes and no. You can learn a program from an existing control but it will loose the structure of how it was laid out. It will stack the blocks on top of one another and if they were named I believe...
Without a backup you wouldn't have these virtual/xl10 folder files, so I don't follow.
What are the back up service settings? Is it excluding history and alarm dbs? Use station copy and make sure that copy alarm and histories are turned on for station copies and then review the size of...
They are the actual programs that should be present in the controllers. If you delete them and open a controller in engineering mode you will see a blank page. When placed in engineering mode you are...
It may not have web services enabled or possibly non standard ports. Like previously stated, ping it, do you get a response. There is a USB port that can be used for ethernet access and has DHCP....
What are the spring rates on both actuators, reverse or direct acting, is the valve norm open or closed and do they have positioners?
Dump the pneumatics entirely or add another EP and control the valve and actuator separately with the Distech controller as you would any other unit ventilator. I dont understand why any restrictor...
Manually add an enum point using add button at the bottom of the database pane and manually enter all the necessary fields to it. That should work.
Add it as enum and enter the values into the enum range.
Tried one the other day on a SE, no luck, there is no web ui for configuration of the unit controller. There is mention that it is the replacement for the MAP but one of the CVT manuals mentions...
The high limit reads the pressure within the unit. This is a mechanical switch and used as a safety should the duct get blocked or the downstream transmitter fails. The duct pressure is measured 2/3...
Where did you get a 90 degree return temp from? My unit had less than a 20 degree rise. This is from what was posted Return Air Temperature: Input Not Available A supply temperature setpoint of 100...
Perform a combustion test. I had a unit about 15 years ago with a low temperature rise. After performing a combustion test and finding readings that were way off, I pulled the burner apart. Found...
If you look at the IOM, it shows examples of wiring for a thermostat. It also shows the differences when using a thermostat or programmable controller. Look at a Viconics VT8350U5000B or contact...
Considering that sensor is for MPS style units the fan is probably what's running all the time. Post the model of the RTU.
Yes you can and they are required. Support pack and productivity something, cant remember the name, also needs to be installed. When you add them you select the folder for the installation path of...
If they werent addressed for the DNET, that is probably the issue.

I agree. A quick search and there is a photo of one with a date code 2508 and 4305.
Technically nothing. A few of the companies I have worked for had dedicated techs that dealt with preventive maintenance, which was usually less experienced techs and were classified as such. And...
If you work for a company and they state you need to be part of the on call rotation then yes. Not sure why maintenance would exempt. The only time i have seen a PM tech not part of on call is...
Off the top of my head and I think I am forgetting something. Create layers, assign what you want to the layers. Create an action button linked to hide of the layer. Or maybe the action linked to a...
Missing hx module
First thing that comes to mind is that it is a constant pilot with an automatic relight sequence. Pilot out and cold, glow coil is powered, pilot lit and hot, power sent to the CS and relays to allow...
If you use 0 min and max it will write when changed only. Since its written to flash memory there is no reason to continue writing. Do not do this for constantly changing values for reasons stated...
Any chance there are VFDs attached? Never ran into an issue with current switches in MCCs when attached to off/on motor control.
You cannot link to the override slots 1 and 8. Use a numeric schedule with null as default so when the schedule expires it outputs null and the normal setpoint is used. Link that schedule to input 9...
You wouldn't add it in the discharge line, so water or air cooled, I see no difference.
Easily done with operational equipment when the valves are in the correct location. And if the system is empty its better than dumping 30 lbs into the suction line.
The transformers that size would be rated in KVA. These are not your typical control transformer.
Cut the Canvas Pane, then delete the tabbed pane, then paste into the scroll pane.
Never had constant issues with connections. Points added if writable in the Jace will be writable in the other. Just won't have priority slots. If you need to write to them you need to reverse the...
Is the Tuning policy write on up enabled. What are the other tuning policy settings.
I have worked with those and have never seen that issue or any kind of noise when they operate. There is a calibration process that occurs every 24 hrs. What is causing the noise, actuator or flow?
Someone seems very confused on how this all works, unless I missed something along the way. Metal shavings would be the least of his worries if there is water entering the refrigeration system.
Close replacement, serves the same functions.

This should be in commercial, not controls.
Does it match any of the diagrams in this document.

It went from tripping limits with old contactor, to voltage being applied and no heat output? Is it 3 phase? Any wiring diagram on the unit that you may have taken a picture of?
No VFD, so no more motor protection, unless there was an external inline overload installed. The drive will do a good job at protecting itself which normally leads to it protecting the attached...
There should be an airflow proving switch that needs to close before the heat will run, so if the fan isn't running the heat should never turn on. VPEF has been made for a long time, what controller...
I agree the PUP stuff needed to go a long time ago. From a user stand point they lacked in many ways and yes the BACnet controllers were no better, other than being BACnet. With the limited...
Find the IOM for the unit and read through it, it is easily found with Google.
Looks like it had a remote panel, connected to TB4 Term 6, 7, 8, 9, 10. This would be just for indication of mode. If...
Find what com port the adapter was assigned by windows. Set the driver com port in Niagara. Done. Doesn't matter if it was assigned com 28 it will work.
I use a $30 USB - RS485 adapter connected to my laptop. If you have a demo license you can run any driver on it that allows demo mode without it being licensed.
Looks more like they absorbed, swallowed and left crumbs of a competitor. I dont understand the move to only obsolete everything they essential purchased. They kept the Aspect and Integra from AAM,...
You can run a station on your laptop with a pup network. It will run for 1 hour at a time as unlicensed.
All pup devices have been obsoleted along with solo pro. Future Solo pro licensing for even current holders was unknown the last time I inquired. ABB absorbed AAM.
Sounds like the thermostat is set for electric heat, set it for gas. There should also be setting whether the fan is controlled by the thermostat or unit. Set it for unit control.
The servers were shutdown. The updated license to meet your needs should have been automatically created years ago on the servers. You could try selecting import license and see what happens.
