It sounds like you have a pump or master valve as well as a rain sensor, correct? I usually recommend hooking it all up except for the sensor as it gets connected very different usually. The old sensor usually goes in-line with the common wire which rain causes the common to get disconnected and thereby not allowing power to flow to the valves. Rachio reads the rain differently and skips the watering without recording that it did some watering, etc.
