Station Numbering
Fixed Station Numbering Description
The controller is configured with Fixed Station Numbering.
Each bay is set up to accept a 6 station module and reserve
the station number for future use if a 6 station module is
NOT installed in Bays 2, 3 or 4.
Station numbers are pre-assigned as follows:
Bay 1
Bay 2
Bay 3
Bay 4

Example Of Optimum Installation Of 19 Stations
Module Configuration
Why Proper Configuration Is So Important
Example of installation with station numbering gaps:
d
l
A total of 19 stations are installed.
d
l
The Base Module is installed in Bay 1 and uses Stations
1 through 4.
d
l
A 6-Station Expansion Module is installed in Bays 2 and
3.
d
l
A 3-Station module is installed in Bay 4 and uses
stations numbered 17 through 19.
Because a 3-Station module is installed in Bay 4, only the
first three station numbers assigned to that bay will be
used and the unused numbers will be “reserved” for future
use.
During programming, the controller will skip any unused
station numbers, creating a gap in station numbering.
In our example a 3-Station module was installed in Bay 4, so
stations 20-22 will be unavailable for programming. During
programming the missing stations will show on the display
as 20NOMOD, 21NOMOD, etc.
20NOMOD
STATION
The screen displays “20NOMOD” with the “20” flashing to
indicate that Station 20 (and also 21-22) are unused and
unavailable for programming.

NOTE
: Station numbering gaps will not prevent the
controller from operating properly. It only affects
station numbering. During programming when
connected to AC power, the controller will skip any
unused stations where a module is not installed.
