Loss of Communication
If the sensor and receiver do not communicate within a 24-hour period, the
sensor system will remain in its current state (Active or Monitor). To alert
you to this condition, the Warning icon will be displayed. The Antenna
icon and current air temperature (TWRFS-I only) will be flashing and the
signal bar indicator will be cleared. See Figure 25.
If communication is not restored within 48 hours, the sensor system will
automatically revert to the Monitor mode; allowing automatic irrigation to
resume as scheduled. The Warning and Antenna icons will continue to
flash. On the TWRFS-I model, the temperature is replaced with two dashes.
The Water Conservation indicators will flash in unison. See Figure 26.
Prolonged Active Mode
If the sensor system remains in the Active mode for seven consecutive days,
it will revert to the Monitor mode, allowing the irrigation system to resume
automatic operation.
The Sensor Status indicator will flash continuously and the Warning
icon will be displayed to alert you to this condition. See Figure 27.
Note: A prolonged Active mode generally indicates a stuck sensor.
Check the sensor test spindle to confirm that it moves freely when the sensor discs are dry.
• To reset the receiver, press the Smart Bypass button one time.
