Q: I have a rain sensor, it is raining and the sprinklers are running. Why?

A: It may be that it has not rained enough to trigger the sensor. If this is not the case, check to make sure the receiver is not set on ‘bypass’ and that the controller is not set on ‘rain bypass’. Check the receiver signal light – is it flashing green? This can be due to a temporary weak signal or the battery is low and needs to be replaced.
