finished and returned the ventilation
rate to “normal” operation).
• Pre-purge—If enabled in the
programming (disabled by default),
the space is ventilated with maximum
outside air for 60 minutes before the
occupied start time. (See Startup.)
• Startup—If pre-purge is disabled
(default) and the motion sensor
detects motion during the 20 minutes
after occupied start time, the space is
ventilated with maximum outside air
until 20 minutes after occupied start
time.
• Standby—After the motion sensor has
not detected motion for 30 minutes,
temperature setpoints are adjusted
(down for heating and up for cooling),
and the outside air damper is closed.
• Recovery—After a period in which
the supply fan was off, the space is
ventilated with an increased percentage
of outside air (to compensate for the
previous reduced ventilation).
• Override—Ventilation override has
been manually selected from the DCV
menu, and the space is temporarily
(30 minutes default) driven to the full
ventilation position (for maximum
design occupancy) if it is not already
at that position. See DCV (Demand
Control Ventilation) on page 24 .
VENT OVRIDE (MINS) = Amount of time for
Ventilation Override operation (30 minutes
default). See DCV (Demand Control

MS/TP
For MS/TP communications, connect the EIA-485
wiring to –A and +B terminals on the backplate (see
the relevant model’s installation guide). For Ethernet
IP, and Foreign Device communications (on relevant
“E” models), plug an Ethernet cable directly into the
RJ-45 modular jack on the back of the FlexStat.
To set protocol and parameters for BACnet
communications,
1. Select Active: Configure.
2. Configure the desired protocol.
3. Select Active: [protocol] and restart the FlexStat.
NOTE: Even if MS/TP is the only option in
firmware R2.0.0.6 and later, ACTIVE:
CONFIGURE MUST FIRST BE
SELECTED before any of the values can
be changed! Otherwise the values are read
only.
Only one protocol can be enabled at any time. The
IP/Ethernet modes do not serve as routers for the
MS/TP connection.
To communicate with a KMD-5576 through the data
port at the bottom of the case, IP/Ethernet-enabled
FlexStat models in one of the Ethernet or IP modes
must (temporarily) be set for MS/TP mode (and
restarted)!
