Baseline Systems WaterTec S100 - Manual (Page 8)

Step 3
Setup Sprinkler Controller and Set Cycle Window
2. The cycle window is the time allowed to complete a watering cycle once the first zone has
started watering. The S100 comes preset with a 12 hour window. Adjust this value to be at
least one hour more than your complete cycle time.
Reasons to re-set the cycle window :
● If your system needs more than twelve hours to complete a watering cycle once the
cycle has started.
● If you choose to water your lawn several times per day (this can result in poor root
development).
To set the cycle window hold the “Bypass” button for 2 seconds. This will display the current
cycle window. Use (+)/(-) buttons while holding the “Bypass” button to change the cycle
window to a value between 0 and 24 hours. When the cycle window is finished, and the
moisture is still below the threshold, the cycle window will start again if a valve is running. It
is important the cycle window is set to fit all watering needs plus an additional hour for
padding.

Step 4
Connect the biSensor
NOTE: It is very important that you use waterproof connectors after all connections
have been verified in Step 7.
1. Before burying the biSensor, verify communications by pressing the “Read / Set” button.
A numeric reading indicates success. A display of Er1 or Er2 indicates a wiring error.
Consult the Troubleshooting section on pages 11-12.
2. Manually run the station to which you connected the biSensor to verify connection.
3. Once connections have been verified, disconnect the biSensor from the valve as this
simplifies burial.

SPRINKLER TIMER
Connect sensor wires across valve solenoid.
1. Set your sprinkler controller to apply
1/2” to 3/4” of water to each zone each
day. This will allow the in-ground
moisture biSensor to choose the best
possible days to water. For instructions
on how to check distribution rate, see
STEP 2 on page 15 of the
Troubleshooting section. (If needed,
refer to the sprinkler timer’s manual for
operational instructions).
