Overview; Applications And Installation - KMC Controls FlexStat BACnet Operation Manual

Overview

The award-winning KMC FlexStat series of intelli-
gent temperature/humidity/occupancy-sensing, wall-
mounted, thermostat/controllers are native BACnet
Advanced Application Controllers (B-AAC) for use
in a BACnet system. The FlexStat simplifies net-
worked zone control for common packaged HVAC
equipment, such as packaged rooftop 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
configuration of a wide range of HVAC control ap-
plications.
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 ap-
plication specific requirements of a particular project.

CAUTION
To avoid damage from ground loops and other
communication issues in networked FlexStats,
correct phasing on network and power
