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.

1. Wire the FlexStat’s backplate to the desired
equipment and set the FlexStat’s end-of-line and
input pull-up resistor switches.
2. Select the relevant application and options from
the (Advanced) Application submenu of the
Advanced Menu and other appropriate menus.
3. Congure the FlexStat for the BACnet network.
(See Network Connection on page 16.)
For general mounting and connection details,
including network wiring, EOL termination, power
connections, input/output connections, pull-up

The Input 2 sensor (AI2) can be congured for
discharge air temperature (Type III thermistor is the
default), fan status (dry contact), or unused.
• If set for discharge air temperature, the sensor
can be calibrated and changed from the default
Type III thermistor to a Type II. See (Advanced)
Inputs on page 8.
• If set for discharge air temperature, Trend Log
#2 is automatically created and monitors the
discharge air temperature, but it has no eect on
operation.
• If set for fan status and no closed contact is
detected when there is a call for fan operation, a
Fan Fail Alarm is created. See Alarms on page 11.
• If set for unused, built-in applications will not
use AI2, but the input would be available to
custom programming.

If the FlexStat is used in a BACnet network with UTC
(Coordinated Universal Time) synchronization (via
broadcasting or addressing a single thermostat) set
the UTC Oset value. The UTC Oset value is in
minutes and corresponds to the distance of the local

Access to the Main Menu, Setpoint Adjust, and

each function to None, Operator, or Administrator
through the Access Levels menu. Passwords are set
in the Passwords menu.
Any person can view the display but might not be
able to change any seings without logging in with
one of the three levels of passwords:
• None (Level “0”): No password is required
(everyone has access).
• User (Level 1): See the Menu Items Access Levels
chart.
• Operator (Level 2): See the Menu Items Access
Levels chart.
• Administrator (Level 3): Can access all menus
and change all editable values. DO NOT
FORGET THIS PASSWORD!
NOTE: Seing a password to (the default) 0000
eliminates the password prompt and
allows full access for that level. If no
password is set for ADMIN, no password
prompt will occur. If any password is set
for ADMIN, the menu items accessible
at the various levels are shown in the

Administrator log-in has timed out. Log-
