1. Select the appropriate model for the intended
application and options (see the FlexStat Data
Sheet).
2. Mount and wire the unit (see this Installation
Guide).
3. Congure/program the unit (see the FlexStat
Operation and Application Guides).
4. If necessary, troubleshoot any issues (see the
FlexStat Operation Guide).
5. Operate the unit (see the FlexStat Operation
Guide).

For optimum temperature sensor performance,
the FlexStat must be mounted on an interior wall
and away from heat sources, sunlight, windows,
air vents, and air circulation obstructions (e.g.,
curtains, furniture). Additionally, for a model with
an occupancy sensor option, install it where it will
have unobstructed view of the most typical trac
area. (See the FlexStat Application Guide for more
information.)
If replacing an existing thermostat, label wires as
needed for reference when removing the existing
thermostat.
1. Complete rough-in wiring at each location prior
to thermostat installation. Cable insulation must
meet local building codes.
CAUTION
To prevent mounting screw heads from touching the
circuit board in the thermostat, use only the mounting
screws supplied by KMC Controls. Using other screws
may damage the FlexStat. Do not turn screws in
farther than necessary to remove the cover.
2. If the cover is locked on the backplate, turn the
hex screws in the boom and top of the FlexStat
CLOCKWISE until they (just) clear the cover.
(See Illustration 1.) Pull the cover away from the
backplate (mounting base).
3. Route the wiring through the backplate.
4. With the embossed “UP” and arrows toward the
ceiling, fasten the backplate to a wall handy-box.
BAC-12xxxx models mount directly on vertical 2
x 4 inch boxes, but they require an HMO-10000/
HMO-10000W wall mounting plate for horizontal
or 4 x 4 boxes. BAC-13xxxx/14xxxx models mount
directly on any of those types of boxes.

Connections and Wiring
Wiring Considerations
• Because of the many connections (power,
network, inputs, outputs, and their respective
grounds or switched commons), be sure wiring
is well planned before installation of conduit!
• Make sure that conduit for all wiring has adequate diameter for all necessary wiring. Using
1-inch conduit and junction boxes is recommended! Use external junction boxes above the ceiling
or in another convenient location as needed
to make connections that run to the FlexStat’s
junction box.
• To prevent excessive voltage drop, use a conduc-
tor size that is adequate for the wiring length!
Allow plenty of “cushion” to allow for transient peaks during startup.
• Using multiple conductor wires for all relevant
inputs (e.g., 8 conductor) and outputs (e.g., 12
conductor) is recommended. Grounds for all the
inputs can be combined on one wire.
CAUTION
To avoid damage from ground loops and other
communication issues in networked FlexStats,
correct phasing on MS/TP network and power
connections on ALL the networked controllers is
critically important.
Network Wiring
For Ethernet or IP communications, plug an Ethernet
cable into the RJ-45 jack on the back of the FlexStat.
MS/TP EOL (End-Of-Line) Termination
The controllers/thermostats on the physical ends of
an EIA-485 wiring segment must have end-of-line
termination installed for proper network operation.
(See Illustrations 2 through 4.) If a FlexStat is at the
physical end of the MS/TP network line, set both the
EOL termination switches to On (to the right/up)
on the back of the circuit board. If not on the end,
ensure that both switches are O (le/down).

Input Connections
Passive input devices require pull-up resistors in the
circuit. For passive input devices (e.g., switch contacts and 10K ohm thermistors) on IN2 through IN4
and IN7 through IN9, set the pull-up switches on
the back of the circuit board to the 10K position. For
active voltage devices, set the switches to the 0–12
VDC position. (See Illustrations 3 through 5.)
NOTE: Unlike the EOL switch pairs, the INPUT
switch pairs must NOT have both switches set to the same direction—if one of the
pair’s switches is set to the le, for example,
the other must be set to the right (or vice
versa). ALL the input pull-up resistor
switch pairs must be fully latched in either 10K Ohm or 0–12 VDC position even
if a switch pair has no input connected! A
single incorrect switch position may cause
errors in multiple inputs.
NOTE: Type II or III 10K ohm thermistors can
be selected by changing the menu seing
in Advanced > Inputs > Input # > Sensor
(see the Conguration section). If a remote
space temperature sensor is connected to
AI7, space temperature can be congured
for onboard, remote, averaging of the two,
the lowest reading, or the highest reading.
NOTE: FlexStat inputs do not support 1K ohm
RTDs.
NOTE: To use a 4–20 current loop input or map
analog inputs as binary values, see the
FlexStat Application Guide.
NOTE: To use a remote SAE-10xx CO2 sensor, see
the FlexStat Operation Guide.
NOTE: For more information on wiring specic
applications (AHU, FCU, HPU, RTU), see
the Applications section starting on page
5. (These applications are the packaged
programs selectable from the Advanced
> Application menu in the BAC-1xxx63C
models.)
CAUTION
Relays are for Class-2 voltages (24 VAC) only. Do not
connect line voltage to the relays!
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.
Output Connections
Connect the device under control between the desired
output terminal and the related SC (Switched Com-
mon for relays) or GND (Ground for analog outputs)
terminal. (See Illustration 5).
For the bank of three relays, there is one Switched
(relay) Common connection (in place of the GND
terminal used with analog outputs). (See Illustration
6.) For the relay circuit, the phase side of the AC
should be connected to the SC terminal.

Do not aach a device that draws current exceeding
the FlexStat’s output capacity:
• Maximum output current for individual ANALOG outputs (7–9) is 20 mA @ 12 VDC (each).
• Max. output current is 1 A for individual
RELAYS @ 24 VAC/VDC or a total of 1.5 A per

For example, (discontinued) KMC REE-3211 relays
would exceed the FlexStat’s analog output capacity,
but they can be used with the FlexStat’s internal
relays 1–3 as shown in the following applications
pages. (Use a Core Components CVR11C-0/LD96200
in the REE-3211’s place in those applications.)
FlexStat relays 1–6 are NO, SPST (Form “A”). (To
emulate binary outputs with the analog outputs, set
the output voltage to be either 0 or 12 VDC in Control
Basic.)
NOTE: Applications on pages 5–9 are the packaged
programs selectable from the Advanced >
Application menu in the BAC-1xxx63 (only)
models. Other FlexStat models have other
applications.
NOTE: Humidity, motion, and CO2 sensor options
are dependent on the FlexStat model.
For detailed conguration, operation, troubleshoot-
ing, and other information, see the FlexStat Operation Guide.
Power Connection
The FlexStat requires an external, 24 volt, AC power
source. Use a KMC Controls Class-2 transformer to
supply power. Connect the transformer’s neutral
lead to the 24 VAC Common/–/C terminal and the
AC phase lead to the 24 VAC Phase/~/R terminal.
(See Illustration 5.) Power is applied to the FlexStat
when the transformer is powered.
KMC Controls recommends powering only one controller/thermostat from each transformer. If installing
a FlexStat in a system with other controllers/thermostats powered from a single transformer, however,
phasing must be correct and the total power drawn
from the transformer must not exceed its rating.
Configuration
To congure the FlexStat, navigate the menus and
change seings by pressing a combination of buons.
Press the Right (Menu) buon and then the:
• Enter buon to select and/or exit value editing.
• Up/Down buon to move among entries (up/
down lines).
• Le/Right buon to move among value elds
(le/right spaces).
• Le buon to return to the Home screen.
For additional wiring, customization, program-
ming, and application information, see the FlexStat
Application Guide.
