temperature, mixed air temperature, water
supply temperature, fan status, and other
sensors. Analog inputs accept industry-
standard 10K ohm thermistor sensors, dry
contacts, or 0–12 VDC active sensors.
• A total mix of nine relays (binary) and analog
outputs.
• Configurable password protection, with
three levels of password-protected access
to configuration, scheduling, and setpoint
adjustment, prevents disruption of operation
and configuration.
• Users can easily adjust the setpoint and (if
allowed) change system modes, occupancy
override, and fan speed.
• Built-in scheduling with Entire Week, Weekdays,
Weekend, Individual Days, and Holidays
options for easy configuration. Six On/Off and
independent heating and cooling setpoint
periods per day.
• Multiple built-in alarms and trend logs enhance
system monitoring.
• Integral energy management control with
energy deadband heating and cooling
setpoints, economizer, optimum start, standby,
DCV, and other advanced features. Selectable
constant or intermittent/auto fan operation in
either occupied or unoccupied modes.
• Two-piece design allows field rough-in and
termination of field wiring to the backplate
without needing the FlexStat at the site—
permitting FlexStats to be bulk-configured off-
site and plugged into the wired backplates at a
later time if desired.
• During installation, easily select from the
built-in, factory-tested library of configurable
application control sequences.
All this gives you automation power and support
you would expect to find in much larger building
automation systems—but in a low-cost, high-
value, compact device you can hang on the wall.
Hang it on yours.
• Real-time clock and 72-hour power (capacitor)
backup for network time synchronization or full
stand-alone operation.
• Integral peer-to-peer BACnet MS/TP LAN
network communications on all devices (with
configurable baud rate from 9600 to 76.8K
baud), and “E” versions add BACnet over
Ethernet, BACnet over IP, and BACnet over IP as
Foreign Device.
• FlexStats come with a printed installation
guide in the box. Plus, a large library of
additional support for operation, configuration,
programming, application, and more is
available on the award-winning KMC Controls
web site (www.kmccontrols.com).
