There is hardly a home or business that does not hve some kind of a network in place or wants one or has one that needs some tuning, repair or other service. But the problem is that in this day an age there are too many network "experts" and "gurus" that have mystified the whole process and for any network service at all, you have to hire an expert and have to pay for an evaluation, estimation, diagnostics and a whole lot of other formalites before you can get anything done at all!

At CITS we make everything very simple and straight forward for you. Simply call me directly and I will fly out there and do whatever you need done at your site. All you will be paying is the cost of travel, the air fare, hotel and my per diem and then a simple labor rate of $193.20 per hour, that's it. And of course the cost of materials. Who does that nowadays? Please ask aound and find out. Obviusly I am not looking to get rich here at this point. Just to keep busy and do YOU some good! That's all. Please don't fall for that high sounding network lingo and trust my experience. I solve problems just standing there!!

Remember, the good Microsoft and other great vendors may have invented and put the network systems in place in the first place and the network gururs are great people but they will make you go thrugh a very formal and stiff process. Whereas I will get it working informally and completely before they will figure out what to do even! And I will figure out and setup the network design without even using a piece of paper and pen! Well, may be a pen and a notebook. But I will give you a write up after all is setup. Don't worry there will be some documentation!

My number is (651)442-9044 and is almost alway ON. I am looking for a PROBLEM to fix!

And I forgot to say, I work on networks Small or Lage, at home or abroad. Nothing is too small or too big. I have not said "NO" in my life yet!

Thank you.

CITS0303             Microprocessor-based/DDC Systems


Class Type            Basic Operation


System                   DDC systems


Duration                1.0 Day


Class Audience    Operators of DDC systems such as Excel Plus systems with a Graphic user interface


Offered At             Customer site or St Paul


# of Students        Minimum 5, Maximum 8


Cost                        $2110 per person at site, $1827 per person at St Paul


Brief                      The class starts with a definition of DDC system. After background information on computer controlled DDC systems the class goes into a discussion of the functions/uses of a DDC system. Each function is explained with an example. System components of a DDC system are then discussed. In particular the discussion is centered on the controllers used and their types. The class then discusses the actual loops that a controller can perform and the overrides that can be implemented such as Night Cycle override. It is explained that the controllers also need different  levels of programming to function properly. In particular the data file and program file programming are identified. This leads to the custom programming capability of DDC controllers. The class concludes with examples of actual control loops. In particular the class focuses on the discharge control of cooling with damper sequencing.


                                The class does not use hands on lab stations but class worksheets are used to reinforce learning
