KMC BAC-190000 Series FlexStats Touchscreen Room Sensors/Controllers

KMC BAC-190000 Series FlexStats Touchscreen Room Sensors/Controllers

KMC Conquest™ BAC-190000 series FlexStats provide flexible, set-and-forget control over indoor environmental quality. They can do this as stand-alone HVAC control units without the expense of a large BAS (Building Automation System) or as integrated, networked components of a BAS. FlexStats are wallmounted, touchscreen, combined sensors and controllers. The intelligent integral temperature/humidity/motion/CO2 -sensing, wall-mounted thermostats simplify networked zone control for common HVAC equipment, which can be controlled via the on-board or custom libraries of programs. The integrated schedules, alarms, and trends enable these native BACnet Advanced Application Controllers (B-AAC) to be powerful edge devices for the modern smart building ecosystem. 

Key features include the following:

• A touchscreen operator interface provides system viewing and adjusting for users. The customizable screen features a title bar, room temperature and setpoint displays, four-object icon bar, time and date display, and up to 24 total rotation value displays (e.g., humidity, CO2, OAT, and DAT) in three areas of eight current values each. 

• Up to four internal sensors in a single package minimizes labor, wiring, and wall space, while standard temperature and optional humidity, motion, and CO2 sensors allow expanded energy-efficient control.

• Besides the internal sensors, input terminals for six external inputs are provided. Nine outputs provide a combination of relays and universal (analog) outputs.

• Communication options include BACnet MS/TP, Ethernet, or IP (Normal or Foreign Device). 

• An on-board library of programs permits models to be rapidly configured from the touchscreen for a range of control applications. For demanding custom requirements, these controllers are also fully programmable, using KMC software, to adapt the standard library to the unique application-specific requirements of a particular project.

  • KMC TotalControl™ additionally provides the capability of creating custom graphical web pages (hosted on a remote web server) to use as a remote user-interface for the controllers. 
  •  The IoT platform KMC Commander® provides remote monitoring and control with quickly createable dashboard thermostat and trend “cards” on a PC or mobile device as well as remote alarms and dedicated trend graph pages

    APPLICATIONS 

    BAC-19xx36C models:

    • Air Handling Units 

    • Unit Ventilators (4-Pipe) BAC-19xx63C models: 

    • Fan Coil Units (2- and 4-Pipe) 

    • Heat Pump Units 

    • Roof Top Units These applications can be configured from the touchscreen without using any software. Additional customization and applications beyond the standard library can be created using software.
