Controls Submital Standards
Folks, we are trying to develop standards in developing professional control design submittals....can you give me some ideas on how you do the following
1) symbols ...Temp -pressure or humidity sensors..how do you define these in the symbols page....besides the physical shape do you assign code numbers?
2) system drawing device callouts...assuming you show a device to represent say a temp sensor...do you assign a code to this IE T1-T2..and then a point name ?..do you number these sequentially.....what if you have thermisters and rtd's.....do you use the same code or callout numbers for the same type of sensor from job to job ?....
3) how do you link the sensor device on drawings to the control panel termination locations....so it would be easy for an electrician to install by ?
thank you in advance for any suggestions.....really appreciated
Are you/do you work for a controls contractor? If so you might check the product line you rep. Many product lines have a lot of this in place in which it makes your life easier.

In the controls world there is no such thing as too much detail or information. The installation is only as good as the expertise level of the installer.

Controls submission standards
Hi. I am the senior engineer for the largest owner operated controls contractor in a major Canadian market.
My expectations for a set of shop drawings would include
- symbols are ASHRAE symbols - no need to reinvent the wheel
- a legend of symbols
- a controls schematic for each system
- a sequence of operations for each system
- a bill of materials for each system, and the overall project
- a DDC points list for each controller, sorted by function
- a valve schedule
- a motorized damper schedule
- an index
- a collection of standard wiring diagrams for various point types.
We (and everyone else I know) use Microsoft Visio software and tabloid sized paper.
However much effort you put into shop drawings, you will always run into a consultant that has some additional request , so your style will evolve.
BTW good shop drawings are conducive to predictable installation costs and smooth startups.
Pretty close to what we do.

We use Visio, Excel, and Word but I converted everything to a PDF format so you can see a sampling of how we do things.
Of course, it's not the complete submittal, and deatils about what project, what customer, etc have been removed.
But it shows a cover sheet and table of contents, some of the points sheets for each controller, some of the schedules, and some of the drawings.
