RAIN SENSOR
The Rain Sensor function requires the connection of an external rain sensor with “normally closed” con-
tacts, such as the Toro Wired Rain Sensor (Product Code TRS). When sufficient rain is sensed, the relay
contacts close, resulting in the suspension of the automatic watering programs.
To install and use the rain sensor:
1
Open the Controller box and remove the cover
to reveal the Backup Battery and Control Wiring
Terminals.
Note
: If a rain Sensor is not connected, leave the factory link as supplied
2
Remove the factory fitted link between the
“C” and “R” terminals.
3
Connect the rain sensor to the “C” and “R” terminals,
bringing the 2 wire cable through a hole in the bottom
of the box. The connections are not polarity sensitive.
4
Replace the terminal cover.
5
Turn ON the Rain Sensor switch in the top right corner
of the control panel.
Note:
If left in the OFF position, the controller ignores the condition of the
Rain Sensor
Each station can be individually set to override the rain
sensor. This is useful, for example, if you have an area of
your garden that is under cover and does not receive any
rainfall.
The default position for the rain sensor is “off”, and it must
be turned “on” for each Station:
1

Control Dial

2

3

4
Press and the Station number will flash.
5
Use and to select another Station number and repeat steps 2 to 4 until rain sensing is turned
on for all required Stations.
Note:
When OFF is selected for a station, the controller overrides the rain sensor for that particular station.
Programmed watering may be suspended for between 1 and 10 days, a useful feature if, for example,
rain is forecast in your area for the next two days. Instead of turning the timer off (with the risk of
forgetting to turn it back on), watering can be delayed for three days, after which, programmed
automatic watering will resume at the next start time.
