Johnson Controls released the Metasys CCM09090 Critical Environment Controller, a room-level controller that provides precise control of temperature, humidity, and air handlers for spaces like complex labs with multiple fume hoods and health care facilities.

“The ability to monitor and maintain key environmental parameters at an accelerated rate is paramount to occupant safety and efficiency in critical environment spaces — places like intensive care unit rooms with vulnerable patients,” said Amrita Khemchandani, vice president of building automation systems for Johnson Controls. 

The CCM09090 continuously evaluates and responds to changing airflow and room conditions allowing facility managers and safety officers to consistently meet required critical environment standards set by the American National Standards Institute (ANSI), ASHRAE, American Society for Health Care Engineering (ASHE), and the U.S. Pharmacopeia (USP). Facility managers can also achieve energy savings with unoccupied space setbacks by reducing air changes and optimizing room temperature.

The CCM09090 is BACnet Testing Laboratories (BTL) listed and certified as a BACnet Advanced Application Controller (B-AAC). 

The CCM09090 is available as a standalone controller, panel-mounted, or factory-mounted on a Venturi valve to provide convenience and meet varying facility needs. 

The CCM09090’s fast mechanical response rates enable the controller to respond quickly to changes in pressure caused from doors opening in busy hospitals or fume hood sash movement in laboratories. The controller also provides 18 communication points to equip input/output flexibility. 

It includes pre-engineered controller configuration tool (CCT) applications for pressure and volumetric offset with pressure override to minimize engineering time and ensure standardization. Within the CCT applications, the controller contains pre-engineered .caf files to help users save time on programming. The .caf files are easily cloned so that they can be pushed out to all devices, making commissioning large projects faster and easier. In addition, an expansion module is also available for use with secondary parameters ideal for large spaces.

The CE360 is a wall-mounted display for room parameters controlled by the CCM09090 and provides users with continuous room status awareness. 

Featuring the 360˚ Safety Halo, when set parameters go out of range, the CE360’s screen color and action icon will change to reflect the new state: yellow for warning and red for alarm. Blue represents neutral.
