FlexStat Controller Family BAC-12X/13X/14X Erich Kreuter, KMC Controls, Inc. 1
What is FlexStat? • FlexStat is a family of intelligent, wall-mounted, thermostat/controllers. All models are native BACnet Advanced Application controllers (B-AAC). The Flexstat simplifies zone control for common HVAC systems which can be controlled via the integrated libraries of application programs. • All FlexStats include an integrated room temperature sensor as well as options for integrated humidity, motion, and CO2 sensors. • Application library includes control sequences for RTU, HPU, AHU, and FCU equipment.
Why FlexStat? • FlexStat provides flexible, set-and-forget control of the indoor environmental quality (IEQ) in your space without the expense of a large, centralized building automation system. FlexStat IEQ control optimizes the temperature, humidity, and ventilation for occupant health and comfort. • One-piece, room mounted control solution
FlexStat Features • During installation, easily select from the built-in, “factory” applications (RTU, HPU, AHU, and FCU). • Two-piece design allows easy rough-in and termination of field wiring to the backplate. Allows the FlexStat to be placed safely out of the way or configured off-site for later installation.
FlexStat Features (cont.) • Dot-matrix, high-contrast, backlit display with navigation buttons provide a friendly user interface with plain-English menus for controller configuration. • Display options include display precision, degrees F/C toggle, and configurable rotational values as well as hospitality or lockout modes. • Three levels of configurable passwords protect access to configuration, scheduling, and setpoint adjustment.
FlexStat Features (cont.) • Integral energy management control with energy deadband heating/cooling setpoints, economizer, optimum start, occupancy standby, and Demand Control Ventilation (DCV, via on board or remote CO2 sensor) options. • Built-in scheduling options (Entire Week, Weekdays, Weekends) with six On/Off or setpoint periods each day. • Optional Optimum Start/Stop provides adaptive control. • Integrated hardware Real-time Clock (RTC), with 72-hour backup.
FlexStat Features (cont.) • Networked or stand-alone control • Native BACnet with integral peer-to-peer BACnet MS/TP communications standard on all models. Configurable baud rate from 9600 to 76.8K baud) • “E” versions add Ethernet communication, supporting BACnet Ethernet, BACnet IP, and BACnet IP/Foreign Device. • BTL Listed as an Advanced Application Controller (B-AAC)
FlexStat Features (cont.) • Temperature sensing (standard) with optional humidity, motion (up to 33 foot range), and CO2 sensors. • Six additional analog inputs (field accessible) • Configurable for remote sensors, such as remote temperature, remote CO2, outside air temperature, mix air temperature, fan status, water supply temperature, and more… • Analog inputs accept industry standard 10Kohm thermistor (type II or III) sensors, dry contacts, or 0-12 VDC transmitters. • Nine total outputs (mix of relays and analog, model dependent)
FlexStat Controller Model Overview *NOTE: BAC-13xxxx/14xxxx models have an integrated CO2 sensor. Humidity sensors are standard on 13x/14x models. *NOTE: BAC-1xx1xx models have an integrated humidity sensor (applications support dehumidification). *NOTE: BAC-1x1xxx models have an integrated motion sensor (applications support occupancy operations). *NOTE: To order Ethernet connectivity, add “E” in the part number suffix (BAC-121163CEW). *NOTE: Standard color is white. To order light almond, remove “W” from the part number suffix.
