RainSensor Operation

vAutomatic 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.

vBypass 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.
