Operation with Rain Sensor
US
The timer can be connected to a wired Rain Sensor (item 90915) or to a
wireless RF Rain Sensor (item 90831) + RF Rain Sensor Interface (item
8480).
The sensor informs the timer whenever the rainwater collected in the cup
has reached 0.17 ounces/5 mm ('rain' status), and when the water has
evaporated ('normal operation' status).
The timer suspends the watering program as long as rain status persists,
and the active state of the sensor is displayed (see

The Rain Sensor must be connected to the relative electrical contacts in-
side the water timer, having first removed the jumper from the contacts
➊
(fig.6 -
).
If the Rain Sensor is not going to be used, the jumper must
remain in place across the contacts.
1. RF RAIN SENSOR: install the RF Rain Sensor Interface, routing the
wire antenna through the relative clips (fig.6
2. WIRED RAIN SENSOR: plug in the sensor connector (fig.6
Check that the two-core cable enters the timer by the way of the
recess located on the rear side of the housing (fig.6
