System 450™ is a family of modular, digital electronic controls that is
easily assembled and set up to provide reliable temperature, pressure,
and humidity control for a wide variety of HVAC/R applications,
commercial process applications, and industrial process applications.
The System 450 control system is designed to replace System 350™
and System 27 control systems, and to provide many additional
features and benefits with fewer than twenty model variations.
System 450 control modules provide a field-configurable out-of-the-box
solution. Most System 450 control modules can control temperature,
pressure, and humidity systems simultaneously.
