Max Info Frames
(view only) is the maximum
number of information frames (data packets) that
a controller may send out before it must pass the
token.
For
IP
and
IP Foreign Device
communications,
consult with the system administrator for the
appropriate settings for the IP Address, Subnet
Mask, Gateway, and UDP Port.
Ethernet
communications are essentially plug-
and-play, and the MAC address is not changeable.

Set the desired CO

menu. See
For maximum sensor accuracy,
enter the eleva-
tion (altitude) above sea level
of the building’s
location. (The default value is 0.) Elevation for any
particular location can be found at such sources as
. (For very tall buildings, the
upper floors would have a higher elevation than
lower floors.)
After power is first applied or the FlexStat is
restarted, the sensor goes through a
warm-up
for
approximately half a minute. During the time the
sensor count will be 0 ppm and the Status line
would display WARMUP instead of NORMAL.
The
sensor and its firmware
are identified by the
model, the compilation subvolume (SUB VOL),
compilation date (SW DATE in yymmdd format),
and serial number.
NOTE: With the CO
2
sensor enabled, a trend log
is automatically generated. See
The CO
2
models have a patented self-calibration
technique designed to be used
in applications
where concentrations will drop to outside ambi-
ent conditions (approximately 400 ppm) at least
three times in a 14 day period,
typically during
unoccupied periods.

If the MAR7000 is used in a BACnet network with
UTC (Coordinated Universal Time)
synchroniza-
tion (via broadcasting or addressing a single ther-
mostat) set the UTC Offset value. The UTC Offset
value is in minutes and corresponds to the distance
of the local time zone to the zero degree meridian.
For example, USA/Canada Pacific Standard Time
(8 hours) =
480
minutes and USA/Canada Eastern
Standard Time (5 hours) =
300
minutes.
In stand-alone operation or networks that do not
have UTC broadcasts, setting this value is not nec-
essary.
NOTE: The BACnet standard for this offset
value is: “The time zones to the west
of the zero degree meridian shall be
positive values, and those to the east
shall be negative values.” The value is in
minutes
, not hours.
For areas that observe
DST (Daylight Saving
Time)
, select True/On for DST ENABLE and DST
AUTO. The
DST period is currently the second
Sunday of March through the first Sunday of
November, but these rules can be changed in the
menu if the official period changes or if the in-
stalled location needs a schedule adjustment for
better operation.
NOTE: If DST is enabled but the Auto setting is
not, the actual calendar dates (instead of
using the general rules) will need to be
entered every year.
