TotalControl would show “00:10:00.00”
(hours:minutes:seconds.hundredths of

“60000” (hundredths of seconds) instead.
NOTE: If applicable to the model, the humidity
sensor is AI5 and the motion sensor is
BI6, which can also be configured for trend
logs. See the BAC-10000 Series Application

Resetting the FlexStat
Types of Reset
•
•
Restarts the controller’s Control Basic programs.
Leaves configuration and programming intact.
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 op-
eration, and three types of reset exist:
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 aſter an outage,
the FlexStat will aꢀempt 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.)
•
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 aſter a new Control Basic
program is loaded and compiled.)
•
If problems still persist (or major changes in a
firmware update have taken place) restoring fac-
tory defaults (and reconfiguring and reprogram-
ming 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 re-
start 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 compres-
sors have a default programmed minimum off
time of 300 seconds).

Connect the network wiring and set the EOL switch-
es 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)
The FlexStat is equipped with a PC data port located
at the boꢀom 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 instruc-
tions included with those devices and soſtware.) To
connect to the PC data port:
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.
1. Connect the keyed, flat end of the KMD-5624
interface cable (included with the KMD-5576) to
the port on the boꢀom 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.

issues, see the Motion/Occupancy Sensor section
in the BAC-10000 Series Application Guide.
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 affect mul-
tiple 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 leſt or both to the right—if switch 3 is set
to the leſt, for example, 4 must be set to the right
(or vice versa).

Check that the thermistor is centered in its hole at
the boꢀom 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 addi-
tional thermistor—temperature was derived from
the same chip that measured humidity.)

Definitions of Terms
Native BACnet Device—A device that is fully BACnet
compatible and uses BACnet as its primary, if not
exclusive, method of communication.
For definitions 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
of the more important glossary terms
for this document are included on this page:
PID (Proportional Integral Derivative) Control—A
control algorithm that enhances the PI control
algorithm by adding a component that is pro-
portional to the rate of change (derivative) of the
deviation of the controlled variable. This com-
pensates for system dynamics and allows faster
control response.
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 filters
to condition the air.
BACnet® (Building Automation Control Network)—
An interoperable, nonproprietary, communica-
tion protocol standard conceived by a consor-
tium of building managers, system users, and
manufacturers. BACnet defines how information
is packaged for transportation between building
automation system vendors.
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 be-
tween fully closed to fully open. Within a specific
range, the output response maintains a constant
ratio to the input signal.
Protocol—A definition or set of communication rules
by which information is exchanged between de-
vices on a network.
EIA-485—A serial communications standard in
which the voltage difference between two wires
conveys the data. It is commonly used to network
controllers via twisted-pair wiring. It was for-
merly known as RS-485.
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.
Fan Coil Unit (FCU)—A fan terminal unit that condi-
tions the air in a single room or zone. FCUs gen-
erally contain heating and cooling coils and have
the ability to supply outside air to a space.
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.
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.
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-
Max Master—The highest MAC address a device will
aꢀempt to locate when polling for master devices
on the local network.
play, high-speed, serial computer interface.
UTC (Coordinated Universal Time)—An international
standard for determining time zones.
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.
Variable Air Volume (VAV)—A method of tempera-
ture control in which the volume of constant tem-
perature supply air exiting a duct is modulated
(via dampers) to maintain a temperature setpoint
in an individual space.
