Quick Start
The KMC FlexStat series of intelligent temperature/
humidity-sensing, wall-mounted, thermostat/
controllers are native BACnet Advanced Application
Controllers (B-AAC) for use in a BACnet system.
The FlexStat simplifies networked zone control for
common packaged HVAC equipment by including
an on-board library of programs that permits rapid
configuration of a wide range of HVAC control
applications.
To use the FlexStat:
1. Mount and wire the unit (see this Installation
Guide).
NOTE: This document gives basic mounting,
wiring, and setup information only. For
configuration, programming, operation,
and other information, see the KMC
Controls web site (www.kmccontrols.com)
for the latest documents and firmware. For
installation instructions of FlexStats with
output configurations other than 6 relays
and 3 analog outputs, see that model’s
respective installation guide.
2. Configure/program the unit
(see the FlexStat
Operation and Application Guides).
3. If necessary, troubleshoot any issues
(see the
FlexStat Operation Guide).
4. Operate the unit
(see the FlexStat Operation
Guide).

Cover hex screws
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).
(See the Application Guide for
more information.)
Additionally, for a model with an occupancy sen-
sor option, be sure to install it where it will have
unobstructed view of the most typical traffic area
(see the 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.
2. Turn the hex screws in the bottom and top of
the FlexStat
clockwise
until they 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 toward the ceiling, fasten
the backplate directly to a
vertical
2 x 4 inch wall
handy-box. (For horizontal or 4 x 4 applications,
use the HMO-10000 wall mounting plate.)
5. Make the appropriate connections to the terminal
blocks. (See the Connections and Wiring section.)
6. Place the FlexStat cover over the backplate
while
being careful not to pinch or dislodge any
wiring
. Back the hex screws (
counterclockwise
)
out of the brackets until they engage the FlexStat
cover and hold it in place.
CAUTION
To prevent mounting screw heads from touching the
circuit board in the thermostat, use only the mounting
screws supplied by KMC Controls. Using screws other
than the type supplied may damage the FlexStat.
