Temperature Control Systems And Why They Dont Work

TEMPERATURE CONTROL SYSTEMS: Why Don’t They Work ?

WHAT WENT WRONG?
WILLIAM J. COAD
COAD ENGINEERING

Where We’ve Arrived:
Digital control has replaced analog control with few exceptions
In the very near future, the “exceptions” will have been removed
Hardware is continually improving in reliability and capacity and decreasing in cost

Where We’ve Arrived:
As a percentage of cost, software development, custom programming and commissioning have become much more significant than hardware
Many companies have seriously underestimated the need for and the cost of custom programming and system commissioning. As a result, most systems have failed to perform to their capability.

Benefits of Digital Controls
They are information rich
They are infinitely flexible
They are expandable
