Overview
Applications and Installation
The KMC FlexStat series of intelligent temperature/
humidity/occupancy-sensing, wall-mounted, thermostat/controllers are native BACnet Advanced
Application Controllers (B-AAC) for use in a BACnet system. The FlexStat simplies networked zone
control for common packaged HVAC equipment,
such as packaged rooop units, fan coil units, heat
pumps, and other similar applications. In addition, applications such as pressure dependent VAV,
terminal reheat, and medium-sized central station air
handling equipment applications may also be addressed through the on-board libraries of programs
built into the devices.
The on-board library of programs permits rapid
conguration of a wide range of HVAC control applications.
The FlexStat series also provides the capability to
customize the standard library of sequences using
KMC’s BACstage programming tool. This enables a
local authorized KMC installing contractor to adapt
the standard library to the unique site needs and application specic requirements of a particular project.

Resetting the FlexStat
Types of Reset
If the FlexStat is not operating correctly or if a low
limit alarm has occurred, the FlexStat should be
reset (reinitialized). Any reset interrupts normal operation, and three types of reset exist:
• A warm start is generally the least disruptive op-
tion (restarting normal operation the quickest).
• If problems still persist, try a cold start. (This
should also be used aer a new Control Basic
program is loaded and compiled.)
• If problems still persist (or major changes in a
rmware update have taken place) restoring fac-
tory defaults (and reconguring and reprogramming the FlexStat) may be required.
Warm and Cold Starts
CAUTION
During a restart, the analog outputs go to zero,
and relays go to their normally open state. A restart is a process that lasts around ten seconds,
and it may result in several changes of state
for an output, turning equipment off and on
abruptly. Before resetting the FlexStat, manually
override equipment as needed. If a large fan
is controlled by the FlexStat, for example, set
a minimum off time. See Fan Setup on page 5
(built-in, selectable applications with compressors have a default programmed minimum off
time of 300 seconds).
A warm start does the following in the FlexStat:
• Restarts the controller’s Control Basic programs.
• Leaves conguration and programming intact.
NOTE: Menu changes may take up to about two
minutes to write to nonvolatile Flash
memory. If power to the FlexStat is lost
during this time, changes may be lost.
Restarting the FlexStat from its menu,
TotalControl, or BACstage are the
recommended methods.
NOTE: When power is restored aer an outage,
the FlexStat will aempt to do a warm
start as long as the values in RAM are
retained (up to about four hours). If
the the RAM checksum test fails, a cold
start will be done instead. (In custom
Control Basic programming, using the
POWERLOSS command may be desirable
to determine start-up conditions and to take
appropriate actions—see the Help system
in TotalControl or BACstage for more
information.)

Restore Factory
Restore Factory (restoring the FlexStat to the factory
seings) does the following:
• Clears present values.
• Restores the object database/conguration to the
defaults.
• Restarts the controller’s (factory installed) Control Basic programs.
NOTE: The MAC address and device instance are
not restored to their original defaults, and
custom Control Basic programs are not
deleted. If custom Control Basic programs are
installed, all factory programs are restarted
but all custom Control Basic programs are
halted. Custom programs may be restarted by
loading/running the programs from the CB
Programs menu. See (Advanced) CB (Control
Basic) Programs on page 6.
CAUTION
When returned to factory defaults, analog outputs will go to zero and relays will go to their
normally open state. Before restarting the thermostat, manually override equipment as needed.
CAUTION
After a return to factory defaults, applications are
unconfigured. You must select the desired application and appropriate settings before connected
equipment will operate properly. (See (Advanced)
Application Options on page 5.)
To restore the FlexStat to factory seings:
1. Select Restore Factory from the Advanced > Device menu.
2. When prompted for the required restart, press
Enter. (To Cancel, press the right buon and then

Network Connection
BACnet MS/TP Network Communication
Connect the network wiring and set the EOL switches accordingly. (See the Installation Guide for wiring
and end-of-line switch information.)
From the FlexStat menus, adjust the device instance
number, the MAC address, and baud rate from the
defaults as necessary. Set the Max Master to the
minimum necessary for the network. See (Advanced)
BACnet Device Properties on page 8 and (Advanced)
BACnet Communications on page 7.)
NOTE: The current FlexStat MAC address and
device instance numbers can be viewed in
the About menu. Each BACnet device on a
network must have a unique MAC address
and device instance.
PC Data Port Connection
The FlexStat is equipped with a PC data port located
at the boom of the thermostat housing. This port
provides a temporary EIA-485 (formerly RS-485)
connection to the digital network for network setup
or troubleshooting.
To connect a computer to the port, a means of
converting the EIA-485 signal to a USB or EIA-232
(formerly RS-232) signal will be needed. For USB,
use a KMC KMD-5576 USB Communicator. For
EIA-232, use a third-party interface. (See the instructions included with those devices and soware.) To
connect to the PC data port:
1. Connect the keyed, at end of the KMD-5624
interface cable (included with the KMD-5576) to
the port on the boom of the FlexStat.
2. Connect the modular plug of the cable to the
interface device that converts the EIA-485 signal
from the FlexStat into a USB or EIA-232 signal.
3. Connect the suitable cable from the interface
device to the computer’s serial or USB port.
Install any required soware and congure the
port as necessary.
NOTE: To avoid faulty communication with the
KMD-5576 USB Communicator, the Max
Master number may need to be reduced
to the minimum required for the network
and the driver and latency seings on
the computer may need to be checked or
updated. See Troubleshooting on page 17.

Troubleshooting
Alarm Issues
Alarm, (False) Fan Fail
• Check conguration. Be sure the Fan Status
option is not selected when there is no sensor/
switch for it.
• Check that the IN2 (fan status) input pull-up
resistor switches are fully latched in the correct
positions. Any passive, dry contact should use
the 10K Ohm seing. (See the Connections and
Wiring section of the relevant BAC-10000 Series
Installation Guide.)
• Check IN2 (fan status) input wiring.
• Check the connected fan status sensor/switch.
• Using BACstage or TotalControl, check that AI2
(fan status) is not congured as “Out Of Service.”
Alarm, (False) Low Limit (Freeze Stat)
• Check the Low Limit Alarm seing—see Damper
Setup on page 5.
• Check conguration. Be sure the Economizer
option is not selected when there is no mixed air
temperature sensor.
• Check that the IN3 (mixed air temp.) input
pull-up resistor switches are fully latched in the
correct positions (see the Connections and Wiring
section of the relevant BAC-10000 Series Installation Guide).
• Check IN3 (mixed air temperature) input wiring.
• Check the connected mixed air temperature sensor.
• Using BACstage or TotalControl, check that AI3
(mixed air temp.) is not congured as “Out Of
Service.”
NOTE: Aer a low limit alarm is generated, the
fan will not run until aer the FlexStat
is restarted. See Reseing the FlexStat on
page 14.)
Alarm, (False) Space Temp. or Humidity
• See Alarms on page 11.
• See Temperature Reading Is Incorrect on page 19.
• See Temperature Setpoint Is Not Maintained on
page 19.
• Using TotalControl, adjust the limits or time
delay.
Communication Issues
Firmware Upgrade Fails
• Ensure the WD (watch dog) jumper is temporarily removed during the upgrade process (see the
KMD-5699 Installation Guide, P/N 913-019-04).
Reinstall the pin on the le and center pins aer
the upgrade process is complete.
• Check connections.
• Ensure rmware for the correct model is selected
in the Firmware Upgrade Tool.
NOTE: If rmware for a wrong model is acciden-
tally installed, the outputs will not match the
applications/conguration on the display.
NOTE: Backing up the existing seings and
rmware image before or during the
upgrade process is good practice.
NOTE: Restoring to the factory defaults and
reconguring might be needed if how the
FlexStat operates changes. Read all notes
accompanying the rmware update!
KMD-5576 Communication Faulty
• Upgrade to the latest version of BACstage (ver.
2.4.0.25 or later required).
• Check the seings for the USB port on the
computer (Device Manager > Ports) and the
MS/TP port in BACstage (Access > Connection
Parameters).
• Reduce the Max Master number down to the
minimum needed for that network—see (Ad-
vanced) BACnet Communications on page 7.
• Install latest driver and check latency seings.
See Latency Seings for KMD-5576 Service Bulletin (SB0308A) on the KMC web site.
• See also MS/TP Network Communication Faulty
below.
MS/TP Network Communication Faulty
• Reduce the Max Master number down to the
minimum needed for that network—see (Ad-
vanced) BACnet Communications on page 7.
• Check that EOL switches are fully latched in the
correct positions (see the relevant BAC-10000
Series Installation Guide).
• Check MAC address and device instance numbers.
• Check baud rate.

Cover and Display Issues
Custom Programming and Web Issues
Cover Binds on Backplate
• Carefully remove the FlexStat cover from the
backplate and inspect for bent pins and/or terminal socket connectors. If cover pins are bent, use
a needle-nose pliers to straighten them. If socket
connectors are bent, use a pointed object (such
as a thumbtack or straightened paperclip) to
straighten them. (Pushing the pointed object into
the socket from the back side can be helpful.)
• Replace the backplate.
NOTE: When installing the cover on the
backplate, be sure to not pinch or dislodge
any wiring. Do not use excessive force.
If there is any binding, pull out cover
and examine pins and terminal socket
connectors.
Display Is Blank or Erratic
• Check that Display Blanking is not unintention-
ally enabled. (See System Setup on page 13.)
• Check for a tripped circuit breaker to the transformer.
• Check for proper supply voltage from transformer and that the transformer has enough
capacity (VA) for all connected devices (see their
respective data sheets).
• Carefully remove the FlexStat cover from the
backplate, check pins and connectors, and reinsert. (See Cover Binds on Backplate on page 18.)
• Check connections.
• Put another FlexStat on the installed backplate,
and if the second FlexStat functions properly,
replace the rst FlexStat.
Display Freezes (Buttons Have No Effect)
• Carefully remove the FlexStat cover from the
backplate and ensure the WD (watch dog)
jumper (near the boom of the board) is installed
on the le and center pins. The jumper is temporarily removed during a rmware update and
should be reinstalled when the process is completed. (See the KMD-5699 Installation Guide,
P/N 913-019-04, for more information.) Reinstalling the cover on the backplate will restart the
FlexStat.
Control Basic Programs Do Not Work
NOTE: The FlexStat has a library of built-
in applications and options that are
congured through the FlexStat’s display.
Beyond these standard congurations,
custom changes can be added to a FlexStat
using KMC’s BACstage (ver. 2.4.0.26 or
later) or TotalControl (ver. 2.0.5 or later).
NOTE: Control Basic (read-only) programs 1
through 5 are used for built-in applications
and can not be modied directly. Programs
6 through 10 are empty and can be used for
additional programming. Using BACstage
or TotalControl, a program (1 through 5)
can be copied, pasted into a new program
code object (6 through 10), edited, and
run in place of the original. (Although
programs 1–5 cannot be edited, they can be
halted and set to not autorun aer restart.)
NOTE: Customized programs are the responsibility
of the user. KMC Controls does not provide
support for such programs.
• In the BAC-10000 Series Application Guide (P/N
913-019-03), carefully REVIEW ALL the infor-
mation in the Custom Programming section!
• Set programs to autorun and/or check if they
have halted. Review (Advanced) CB (Control
Basic) Programs on page 6.
• Ensure objects are wrien to correct priority
levels. See the Custom Web Graphics section in
the BAC-10000 Series Application Guide (P/N
913-019-03).
• Custom programming requires BACstage (ver.
2.4.0.26 or later) or TotalControl (ver. 2.0.5 or
later). Upgrade to the latest version for the most
complete functionality.
• For assistance with Control Basic commands, see
the Help system in TotalControl or BACstage.
Custom Web Graphics Do Not Work
• In the BAC-10000 Series Application Guide (P/N
913-019-03), review the Custom Web Graphics
section.
• See also Control Basic Programs Do Not Work
above.
BAC-10000 Series 18 Operation Guide, Rev. J
Page 19
Input, Sensor, and Value Issues
Input Values Are Outside the Expected Range
• Check that ALL the input pull-up resistor
switches are fully latched in the correct positions.
See the Connections and Wiring section of the
relevant BAC-10000 Series Installation Guide. A
single incorrect switch position may aect multiple inputs. All input switches must be latched
in either 10K Ohm or 0–12 VDC positions even
if no input is connected! Input switch pairs (3-4,
5-6, and 7-8) must never have both switches set
to the le or both to the right—if switch 3 is set
to the le, for example, 4 must be set to the right
(or vice versa).
• Check that the correct input type is selected on
the Inputs screen. A Type III thermistor is the
default on IN2 through IN4. See (Advanced)
Inputs on page 8.
• Check input wiring. See Wiring Issues on page 21.
• Check connected sensors.
• Using BACstage or TotalControl, check that the
input is not congured as “Out Of Service.”
• Restore the FlexStat to factory seings (see Reset-
ting the FlexStat on page 14) and recongure.
Motion/Occupancy Sensor Does Not Work
• The initial rmware (R.1.0.0.0 and earlier) did not
support this sensor within the built-in selectable
programs. Custom programming was required—
see the BAC-10000 Series Application Guide, P/N
913-019-03. Upgrade to the latest rmware for
built-in support.
• Aer an initial power-up or restart, the motion/
occupancy sensor requires about 30 seconds
before it will begin responding to motion.
• The motion/occupancy sensor initiates override
only during “o” times in the schedule. See
Schedules on page 12.
• Check that the motion sensor is enabled and
detects motion. See (Advanced) Motion Sensor on
page 8.
• Using BACstage or TotalControl, check that BI6
(occ status) is not congured as “Out Of Service.”
• The FlexStat must be installed where there is a
clear view of typical trac area (reliable range is
out to about 33 feet). Remove or move obstacles.
Reinstall the FlexStat in a more optimal location
if necessary.
• Connect remote motion sensors to an input
(requires custom programming).
• For more information on detection performance,
paerns, conguration, programming, and other
issues, see the Motion/Occupancy Sensor section
in the BAC-10000 Series Application Guide.
Temperature Reading Is Incorrect
• Aer applying power for the rst time (or aer
an outage), allow the FlexStat to self-calibrate a
few minutes before verifying temperature reading.
• If the discrepancy is small, adjust the calibration
oset—see (Advanced) Inputs on page 8.
• Check that the thermistor is centered in its hole at
the boom of the case and has an air gap around
it. Also check that its leads are not pinched,
shorted, or broken and that the tape holding
down the leads is not loose. (Some early models
with humidity sensors did not have the additional thermistor—temperature was derived from
the same chip that measured humidity.)
• Using BACstage or TotalControl, check that
AI1 (space temp.) is not congured as “Out Of
Service.”
• Check that the FlexStat is not mounted on an
outside wall, is not exposed to heat sources or
sunlight, is not exposed to dras from windows
or air vents, or is not blocked from normal air
circulation.
• See also Input Values Are Outside the Expected
Range on page 19.
Temperature Setpoint Is Not Maintained
• Select Occupied mode from the Home Menu—
see H/C, Fan, Occupancy, and Override on page 3.
• Override the fan to On from the Home Menu—
see H/C, Fan, Occupancy, and Override on page 3.
• Check that the appropriate application is selected—see (Advanced) Application Options on
page 5.
• Check that room temperature is being sensed
correctly—see Temperature Reading Is Incorrect
on page 19.

Output, Fan, and Relay Issues
Analog Output Does Not Work
CAUTION
Do not mistakenly connect 24 VAC to an analog
output ground. This is not the same as a relay’s
switched common. See the backplate’s terminal
label for the correct terminal.
NOTE: The maximum current of an analog output
is 20 mA @ 12 VDC. Excessive loads will
be clamped at the maximum. Relays may
chaer or fail to latch if they need more
current than the maximum allowed. KMC
REE-3111/3112 relays, for example, could be
connected to the analog outputs, but REE3211/3221/3213 relays would not operate
reliably with analog outputs because their
required power exceeds the FlexStat’s
capacity. (REE-3211/3221/3213 relays could,
however, be used with the FlexStat relays
and a separate power source.)
• Check current draw of load—it must be 20 mA or
less. Substitute an output device that draws less
current.
• Check that the output is on.
• See Wiring Issues on page 21.
• See also Fan Does Not Run on page 20.
• If Restore Factory has just been performed, see
the Note and Cautions in Restore Factory on
page 15.
• If the rmware has just been upgraded, rmware for the wrong model type may have been
installed (e.g., BAC-1xx63 rmware accidentally
installed in a model BAC-1xx36). In the About
menu, ASV may simply read “CUSTOM” instead
of something like “BAC_1xx36 R1.1.0.5” as it
normally would have done. If so, repeat the rmware upgrade and ensure that the correct type of
rmware is selected for the connected model.
NOTE: ASV in the About menu will also show
CUSTOM if any built-in Control Basic
program (1–5) is not running or has autorun disabled.
Fan Does Not Run
NOTE: The animated fan icon is coupled with
BV18 in the packaged programming (not
the actual fan output terminal).
• Select Occupied mode from the Home Menu—
see H/C, Fan, Occupancy, and Override on page 3.
• Override the fan to On from the Home Menu—
see H/C, Fan, Occupancy, and Override on page 3.
• See Wiring Issues on page 21.
• Check that the appropriate application is se-
lected—see (Advanced) Application Options on
page 5.
• Check the fan conguration—see Fan Setup on
page 5.
• Restart the FlexStat. Aer a low limit alarm is
generated, the fan will not run until aer the
FlexStat is restarted. (See Reseing the FlexStat
on page 14.)
Relay (Internal) Does Not Work
CAUTION
Relays are for Class-2 voltages (24 VAC) only.
Do not connect line voltage to the relays!
NOTE: Max. output current is 1 A for individual
relays @ 24 VAC/VDC or a total of 1.5 A
per bank of 3 relays (relays 1–3, 4–6, and
7–9). Do not aach a device that draws
current that exceeds the corresponding
value. Relays are NO, SPST (Form “A”).
• Check current draw of load. Substitute an output
device that draws less current.
• Check that the output is on.
• See Wiring Issues on page 21.
• Restart the FlexStat.
• If Restore Factory has just been performed, see
the Note and Cautions in Restore Factory on

Programming (Custom)
The FlexStat has a library of built-in applications and
options that are congured through the FlexStat’s
display. Beyond these standard congurations, custom changes can be added to a FlexStat using KMC’s
BACstage (ver. 2.4.0.26 or later) or TotalControl (ver.
2.0.5 or later). See the BAC-10000 Series Application
Guide (P/N 913-019-03) for more information.
NOTE: Customized programs are the responsibility
of the user. KMC Controls does not provide
support for such programs.

Definitions of Terms
For denitions of various terms in this
document, refer to the award-winning
pocket-sized Green Building and Con-
trols Glossary (SB-046). A hyperlinked
online version can be downloaded from
the Brochures section of KMC Controls
web site, www.kmccontrols.com. Some
of the more important glossary terms
for this document are included on this page:
Air Handling Unit (AHU)—An HVAC system compo-
nent that conditions and delivers air through the
system. It typically contains one or more supply
and return fans, heating/cooling coils, and lters
to condition the air.
®
BACnet
(Building Automation Control Network)—
An interoperable, nonproprietary, communication protocol standard conceived by a consortium of building managers, system users, and
manufacturers. BACnet denes how information
is packaged for transportation between building
automation system vendors.
EIA-485—A serial communications standard in
which the voltage dierence between two wires
conveys the data. It is commonly used to network
controllers via twisted-pair wiring. It was formerly known as RS-485.
Fan Coil Unit (FCU)—A fan terminal unit that condi-
tions the air in a single room or zone. FCUs generally contain heating and cooling coils and have
the ability to supply outside air to a space.
Heat Pump Unit (HPU)—A unit that uses direct
expansion to remove or add heat to a space. On
a call for heat, the heat pump pulls heat from a
source such as outside air or the ground and puts
it into a space. On a call for cooling, the process is
reversed.
Max Master—The highest MAC address a device will
aempt to locate when polling for master devices
on the local network.
MS/TP (Master Slave/Token Passing)—A protocol
(using the EIA-485 signaling standard) in which
master devices can initiate requests for data but
slave devices cannot (since slaves can only reply
to messages from other devices). KMC advanced
application controllers are all MS/TP master
devices.
Native BACnet Device—A device that is fully BACnet
compatible and uses BACnet as its primary, if not
exclusive, method of communication.
PID (Proportional Integral Derivative) Control—A
control algorithm that enhances the PI control
algorithm by adding a component that is proportional to the rate of change (derivative) of the
deviation of the controlled variable. This compensates for system dynamics and allows faster
control response.
PID Loop Controller—A controller with an algorithm
that calculates an output value that is based on
the sensed value and the required setpoint. PID
loop controllers provide more accurate and stable
control than simpler controllers.
Proportional Control—A type of control in which a
controlled device may operate at any position between fully closed to fully open. Within a specic
range, the output response maintains a constant
ratio to the input signal.
Protocol—A denition or set of communication rules
by which information is exchanged between devices on a network.
Real Time Clock (RTC)—A device that keeps track of
the current time in a controller even if power is
interrupted for a period of time.
Relative Humidity (RH)—The ratio of the amount of
water vapor in air to the maximum amount of
water vapor that could be in the air if the vapor
were at its saturation conditions.
Roof Top Unit (RTU)—An HVAC unit that is supplied
as a package and installed outside of a building.
Router—A device that connects two or more networks
and chooses the best path for data packets.
USB (Universal Serial Bus)—A popular, plug-and-
play, high-speed, serial computer interface.
UTC (Coordinated Universal Time)—An international
standard for determining time zones.
Variable Air Volume (VAV)—A method of tempera-
ture control in which the volume of constant temperature supply air exiting a duct is modulated
(via dampers) to maintain a temperature setpoint
in an individual space.
