Brief                      The course starts with a brief introduction to an Excel Plus Graphic Central System using a simplified block diagram. The function and intent of a DDC program in an Excel Plus panel is then elaborated on and the difference between an Energy Management and a DDC program pointed out. The course then goes on into a study of the elements of the Honeywell Programming Language Deltanet Pascal, the language DDC programs are written in. Each set of elements of the language is introduced with an example program segments which is actually tested on line. The course also discusses the powerful Honeywell DDC operators which convert the Deltanet Pascal language into a truly structured programming language ideally suited for HVAC control. The operators are actually used in program segments and tested on line. 

To perform the above noted functions the course points out how the Customer Program Pak provides an editor to write a program, then a compiler to convert the program to executable code and then a downline load function to test and checkout the program on-line. All this is learned with detailed written Lab exercises.

The technical functions of flowcharting, writing, compilation, downloading and testing of programs are performed repeatedly to enhance learning and internalizing a certain definitive analytical thought-pattern.

Objectives             Upon completion of the course the student will be able to:

·         Identify the point and program files of an R7044 Controller database

·         Understand the nature and significance of an HVAC Control loop

·         Flow-chart an HVAC Control loop using Deltanet Pascal Standard Programming Symbology

·         Use the Editor program provided in the Customer Program Pak to write program code to implement a flow-chart for an HVAC control loop

·         Compile program code into the executable/object code format using the Pascal Compiler

·         Download object code for a DDC program into an R7044 memory

·         Test/checkout a downloaded program for correct on-line operation 

·         Use all Honeywell Pascal HVAC operators to write error-free and easily understood    

programs

·         Eliminate the use of the ‘IF’ statement from any already written programs to enhance program functionality and readability for trouble shooting purposes
