Installation Guide, Rev. C
Configuration
To configure the FlexStat, navigate the menus and
change settings by pressing a combination of buttons.
Press the Right (Menu) button and then the:
• Enter button to select and/or exit value editing.
• Up/Down button to move among entries (up/
down lines).
• Left/Right button to move among value fields
(left/right spaces).
• Left button to return to the Home screen.
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 CO
2
sensor options
are dependent on the FlexStat model.
For detailed configuration, operation, troubleshoot-
ing, and other information, see the FlexStat Opera-
tion Guide.
For additional wiring, customization, program-
ming, and application information, see the FlexStat
Application Guide.

Applications Notes and Cautions
CAUTION
Relays are for Class-2 voltages (24 VAC) only. Do not
connect line voltage to the relays!
Do not mistakenly connect 24 VAC to an analog
output ground.
NOTE: Do not use REE-3211s with analog outputs!
See Output Connections on page 3.
NOTE: For Bill of Materials listings of the various
accessories shown in the sample diagrams,
see the FlexStat Application 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 con-
troller/thermostat from each transformer. If installing
a FlexStat in a system with other controllers/thermo-
stats powered from a single transformer, however,
phasing must be correct and the total power drawn
from the transformer must not exceed its rating.
Maintenance
Remove dust as necessary from the holes in the top
and bottom. Clean the display with a soft, damp
cloth and mild soap.
To maintain maximum sensitivity of the built-in
motion sensor, occasionally wipe dust or dirt off the
lens—but do not use any fluid on the sensor.
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: The KMC REE-3211 is discontinued. Use Core
Components CVR11C-0/LD96200 in its place.
Do not use either with analog outputs! See
Output Connections on page 3.
