SMRT-Y Soil Moisture Sensor
26
Special Notes
1.
This Soil Moisture Sensor is compatible with installations using pump start relays.
2.
You can use this Soil Moisture Sensor with installations running multiple stations or valves
simultaneously.
3.
This SMRT-Y Soil Moisture Sensor can be used with a Rain Bird Rain Sensor (part number: RSDBEX). The
system will operate as follows:
•
Connect the Rain Sensor to the sensor terminals inside your controller as directed.
•
Connect the SMRT-Y user interface to the controller as described in this manual.
•
When the rain sensor is activated, the common wire will be disrupted and the power to the SMRT-Y user
interface may be disabled. If this occurs, the display will go blank and the user interface will cease to
function until the rain sensor has dried out. The SMRT-Y programming will not be lost. Even if the user
interface was in bypass mode, that mode will be restored when power is reapplied.
•
When power is restored the SMRT-Y user interface will immediately take a moisture reading and set
either the ‘Suspended’ or ‘Allowed’ mode. The 30 minute timeout requirement will be reset so that the
mode change will occur immediately.
4.
Long-term exposure to direct sunlight could damage the SMRT-Y LCD display. Use the protective cover
(see Figure 12) when installed in direct sunlight.
