Weather Sensor System Operations

The XTRA Smart Weather Sensor system provides two important elements of weather information to the
EC·XTRA timer: Rain/Freeze Hold, and Watering Schedule Management.
• Rain/Freeze Sensor Feature
The Rain/Freeze sensor signals the Smart Pod to suspend automatic watering when
it has detected a specified amount of rainfall, or the temperature drops to near-
freezing. The red
and turn Off when the automatic watering schedule resumes.
Note: To bypass the Rain/Freeze sensor function while watering is suspended, press
the ENTER button to select the Sensor Bypass mode. The red
blinking, and watering operation will resume as scheduled. To return to sensor-controlled
operation, press the ENTER button again.
Important: Freeze sensors should always be used in conjunction with visual checks of the sprinkler system. While
the Weather Sensor is designed to postpone watering when air temperature is detected near freezing, watering can
still occur under certain conditions. For example, the air temperature may rise above the sensor shut-off point, while
the temperature of the landscape and walkways remains below freezing. Or, a drop in air temperature may occur so
rapidly, the sensor is unable to suspend scheduled watering in time. Watering in these conditions can result in icing!
• Watering Schedule Management Feature
The EC·XTRA watering schedule is managed by the Weather Sensor system by
continuously monitoring key weather conditions, and sending this information
to the Smart Pod/EC·XTRA. The watering run time duration is evaluated and
automatically adjusted up or down according to the current demand for irrigation.
When an adjustment occurs, the percent symbol (%) is visible in the timer display.
Note: To view the actual % adjustment value, turn the EC·XTRA dial to Season Adjust.
Refer to the EC·XTRA User's Guide for detailed Season Adjust feature information.
