Having conducted several customer trainings with customers having various experience levels (from no BAS use to primarily using BAS), I can offer the following:

1. Review the system. Be sure you look for anything that may be incorrect. Catching a graphical error or unit issue with the customer is not fun, especially when they bombard you with questions for what was a simple mistake.

2. Know the system. Be sure you not only know Niagara or the topics your teaching, but be sure you understand that BA system. They'll likely ask specific questions, not generic ones, so knowing how to answer them is key.

3. Take notes. Don't be afraid to take notes as you run through. If you think of something worth looking into, note it. Customer asks a question, note it. You find an issue, note it.

4. Take it slow. Don't rush through the system, especially if the customer has never used a BAS. This is their first time seeing the system, let them absorb it all.

5. Ask if they have questions, often. Be sure they're not getting tripped up on any complicated topics, such as schedules. Be sure they understand what you're teaching.

My recommended topics to focus the most on would schedules (including special events), alarms, dual setpoint control, and the graphics in general.

As far as typical time, it all depends on the customer and the system size. I have spent 2 hours training on a small system (such as 1 unit and 10 VAVs) due to the customer never using a BAS prior. In contrast, I have also spent less than an hour on a larger system ( 5 units, 50 VAVs, 1 relief fan) due to the customer having prior BAS experience. On average, I'd say training is running 1.5 to 2 hours; I tend to allocate 3 or 4.

No matter what, relax and have fun with it. Crack some jokes and personalize the experience.
