The System 450™ Series of microprocessor-based modular controls provides versatile, compact, cost-effective, and accurate digital control for a variety of HVACR and industrial controls applications. The nine model variations are each designed to be multipurpose, adaptable, and field configurable. They can monitor and control temperature, pressure, and humidity simultaneously. The enhanced design creates a versatile and durable custom control system that allows the user to monitor and control multiple control loops. The controls are designed to replace the System 350 and System 27 Series control systems, and can handle hundreds of custom applications, including heating and/or cooling control, boiler temperature reset, fan control, floating pressure of an actuator, and humidification/dehumidification control.
