Upper Threshold Moisture Sensor-Based Watering
When you configure the BaseStation 1000 to use the upper threshold watering strategy, you are telling
the controller to start watering based on a day and start time and stop watering when the biSensor
detects that the moisture content in the soil has reached the upper limit, which is equivalent to field
capacity.
Overview of the Steps for Configuring the Upper Threshold Watering
Strategy
Perform the following steps to configure the controller for upper threshold watering:
Step 1 – Install the biSensor in the landscaping according to the instructions that came with the device.
Step 2 – In the BaseStation 1000 controller, search for and assign the biSensor.
Step 3 – Set up the biSensor and assign that sensor to the zone that will water it.
Step 4 – Assign the zones in the area that is monitored by the biSensor to a program by giving the zones
runtimes.
Step 5 – Set up a Day & Time start condition for the program.
Step 6 – Set up the Soak Cycles for the program.
Step 7 – Set up the stop condition and the limit: you can find the limit manually or you can calibrate the
biSensor to find the limit.
Step 8 – Set the controller to run.
Step 1 – Installing the biSensor
The biSensor needs to be placed in the effective root zone of the plant it is monitoring. Usually the
biSensor will be making the irrigation decision for many plants or even multiple zones of plants with
similar water needs, so it should be placed in the effective root zone of a representative plant.
Take note of the serial number of the biSensor that you are installing in the landscape. You will need this
number when you program the controller.
Follow the wiring instructions in the biSensor installation guide to connect the biSensor to the two-wire
path or to the biSensor ports on the controller or on the powered biCoder.
Make sure that you maintain polarity on the wire connections.
Fasten the wiring with wire nuts, and then test communication with the controller before you complete
the installation with waterproof connectors.
