TBOS

Field Transmitter
Multiple stations and programs
If you want more than eight start times per day on a
site equipped with only one valve, you can wire the
valve to several stations on a Two or Four Station
Control Module and program multiple start times
for each station.
For example, if you wire the same valve to both sta-
tions on a Two Station Control Module, you can
obtain up to 16 starts (2 x 8). If you connect the same
valve to three stations on a Four Station Control
Module, you can obtain up to 24 starts (3 x 8).
Stations assigned to this valve, however, cannot be
assigned to other valves. If you use this method,
make sure that there is no program overlap. The pro-
gram run time must be shorter than the time inter-
val separating the two start times.
Note: A One Station Control Module can
use only one program.
Now you can begin setting up your watering cycles.
Standard and Turbo modes
The TBOS Field Transmitter has two modes of opera-
tion: Standard and Turbo.
The Standard mode of operation is identical to the
UNIK Field Transmitter. This mode offers only the 7-
day cycle and is useful when only 7-day (custom)
cycles are needed or when using the TBOS Field
Transmitter to program UNIK Control Modules.
Note: Standard mode is the default
mode of operation.
The Turbo mode offers even day, odd day and odd-
31 (odd days with the 31st of the month) cycles and
1 through 6 day cycles for use with TBOS Control
Modules.

Note: If the display shows AM and the
current time is actually PM, advance or
reverse the clock until the display
shows PM.
Important: When you change the batter-
ies in the Field Transmitter, the time
reverts back to the 24-hour display.
Programming the Field
Transmitter
Before you begin programming the Field
Transmitter, please take some time to learn
some of the programming and connection
options you have with your irrigation system.
Three independent programs
The Field Transmitter has three programs:
A, B and C. This allows you to select a program
according to plant type; for example,
A for grasses, B for shrubs and C for trees. Stations
assigned to the same program operate sequentially.
For seven day cycles, these are independent pro-
grams. You can consider each program as a separate
controller with its own water days, start times and
run times.
For odd, even or 1 through 6 day cycles, all pro-
grams use the same water days but start times and
run times may be programmed independently for
each program.
Note: A station may be assigned to only
one program, either A, B or C.
Simultaneous watering start
If you assign a separate or different station to each
program with the same water days, start times and
run times, you will obtain an almost simultaneous
start of all three stations.
