GFB. The LogiStat microblock supports the
LogiStat, LogiStat Plus, and LogiStat Pro
sensors.
If you are using WebCTRL, you do not need to
enter point identifiers for this microblock in
Eikon for WebCTRL or WebCTRL. If you are
using SuperVision, you do not need to enter
channel numbers for this microblock in Eikon
or SuperVision. For more information, refer to
the Eikon for WebCTRL Microblock Reference
Guide or the Eikon Microblock Reference
Guide.
The U141v+ has an improved flow control
algorithm designed to reduce wear and tear
on the actuator motor. Since this actuator is
covered by the module warranty, you must
use the Airflow Control and Zone Controller
microblocks in the U141v+'s GFB. Refer to the
Eikon Microblock Reference Guide for details
about these microblocks.
You do not need to use BACnet microblocks
when writing the GFB, unless you have a
BACview Keypad Display connected to the
UNI. You must then use BACnet point
microblocks to access U141v+ points through
the keypad.

Point Identifiers

A point can be identified in WebCTRL by its
point number and point type; in SuperVision,
a point is identified by its channel number. On
both systems, expander number zero
represents I/O points on the U141v+.
Point Identifiers in WebCTRL
Enter the point identifiers in Eikon for
WebCTRL before the FB is made or on the FB's
Properties page in WebCTRL. Set the type,
number, and minimum and maximum
present values for each point on the U141v+.
Select a physical point type from the Point
Type field and enter the number of the input
or output. If needed, enter an expander
number. To scale a linear signal type, enter
Revised 8/14/02 • U141v+
the appropriate minimum and maximum
present values on the microblock's dialog
box.
If you are not using a LogiStat in a WebCTRL
system but would like to use the two inputs
that are available on the LogiStat port, assign
an address of 16 for the temperature input
and 17 for the setpoint input.
Channel Numbers in SuperVision
Refer to Table 2 and Table 3 for channel
numbers for each physical point on the
U141v+. The channel number, offset, and gain
for each point can be entered in Eikon before
the Function Block is made, or on the FB's
Parameter page in SuperVision.
