Point Addresses
A Point Address uniquely identifi es a point within the WCC
III system. All point addresses have an associated “analog” or
“binary” value. The term “analog” simply means a value which
is represented by a number (such as room temperature, duct static
pressure, etc.). The term “binary” means the value is represented
by one of two conditions, ON or OFF. An input is a signal sent
to the WCC III system, and an output is sent from the WCC III
system. Therefore, room temperature is an analog input, fan status
is a binary input, and controlling a fan relay is a binary output.
In addition to the inputs and outputs that are wired to the SAT III
controllers, there are several software point addresses within the
system. For example, the WCC III system has 128 week schedules.
This means that separate day/night schedules can be assigned to
128 different areas of the building.
For example, assume that you have three different areas in a
building that have different schedules as shown in the following
table.
Area Occupied Time
Week Schedule #1 1st Floor West 8:00 am - 5:00 pm, M-F
Week Schedule #2 1st Floor East 7:00 am - 7:00 pm, M-F
Week Schedule #3 2nd Floor 9:00 am - 4:00 pm, M-Th
Week Schedule #1 is named W1, and the value of W1 will be On
between 8:00 am and 5:00 pm, Monday through Friday, etc.
The Name column in the table that follows is the name that you
should use when specifying a point address to the system. The “n”
is where a “point number” for the point address is to be entered.

Constant Point Addresses
The following list shows several point addresses within the
system that are always available for use on many of the data input
screens.
Name Description Associated Data Type
0 Logical Zero Always Off
1 Logical One Always On
//// Logical Null Ignored
. . . . Logical Off Always Off/Not Used
NOTE: When a point option is not required, replace the
default value (/ / / /) with either a zero (0) or dot (. . . .)
to force the system to realize that the option is always
OFF. If the slashes are not replaced, the system will
ignore that input and the system can, in rare cases, see
the slashes as being ON.
