Programming Schedules with the Graphical Schedule Editor

There are a few different ways to program a Schedule on a point in CBAS. Go to any output point in CBAS, click the point and go to Program. Then click the Program Schedule button. The most apparent way is to click on a day in the first cycle column and it gives you choices. It’s pretty intuitive because it gives you the appropriate choices and when you make a selection, it goes to the Time column and so forth. Pretty simple.

Controls, Arkansas State University

Tell us a little about yourself…
I’m the youngest of 4 children, born in Walnut Ridge, Arkansas to a farming family. We had 300 acres of rice and soybeans. I took computer science in high school and have been working with computers ever since.

I’ve been at ASU for 17 years where I started in the electrical department and was moved to the controls department when they learned I had a computer background. At the time I started, we had 4 control systems: Trane Tracer, Honeywell, KMC, and Computrols. We have since moved away from the other controls systems and have replaced 90+% of the older controls with Computrols with more being replaced every day. I’ve now been using Computrols Building Automation System for about 15 years. Continue reading CBAS Power User: David Foster

Plant Engineer, Saddleback College

Tell us a little about yourself…
I have been in the HVAC trade for 34 years now, with my past 22 years at Saddleback College. My first introduction to building automation was a Barber-Colman Network 8000 system featuring a server the size of a small desk and 8” floppy disks for backups. It seems DDC technology has improved a little since then. Continue reading CBAS Power User: Alan Cherry

Show Point Relations

Did you know that you can easily discover how points are related to each other through Logic or PID? This can come in handy when you have an Output point that has been commanded but you don’t know exactly where the command is coming from.

Find a point that you are interested in and click it. If it’s an Input point, it will go straight to the Program Screen. If it is an Output, click Program to get to the Program screen. Then click the Show Point Relations button in the top row to the right of the History button. Continue reading George’s CBAS Tips, October 2018

 

Load Shedding and One Approach in CBAS

 

What is Load Shedding?As I’m sure you know, power companies charge a premium when a certain demand threshold is reached. Load shedding during high electrical demand periods is a good way to lower electrical consumption and avoid paying premium prices for exceeding peak demand limits. Metering or monitoring the load for the building will tell you when that threshold is nearing.

Load shedding will probably not work if the demand follows a bell curve during the day, where the threshold is exceeded for a good portion of the day. In this case, the building needs to find ways of increasing energy efficiency, either by purchasing more efficient equipment, eliminating waste, etc. However, if there is a peak in the demand curve that is exceeded around the same time everyday, load shedding could help. The question is, what can you afford to shut down without making people uncomfortable and angry? Continue reading Load Shedding and One Approach in CBAS
