Toro WIRED RAINSENSOR 53853 - Manual (Page 6)

RainSensor Operation
v
Automatic Operation
When the RainSensor activates due to sufficient rainfall (or freezing conditions
- model 53853 only), watering will be terminated until the RainSensor automati-
cally resets. The reset rate will vary depending on temperature, solar radiation,
humidity and wind—the same conditions exposed to your landscape.
v
Bypass Operation
To bypass RainSensor operation, place the timer’s sensor switch in the Bypass
position, or temporarily remove the RainSensor from the valve common wire cir-
cuit.
Model 53853 only: The freeze sensor is designed to terminate auto-
matic watering when air temperature reaches approximately 3 °C (37°F)
+/- 2 °C. Once freezing has occurred, the air temperature can increase
above the sensor trigger point, while the ground temperature remains at
or below freezing – resulting in icing conditions. Additionally, watering
can occur if the automatic watering schedule coincides with a very rapid
decrease in temperature.
