Connecting a Rain Sensor (optional)

The Rain Dial-R is designed to work in conjunction with Irritrol Rain
Sensor models RS500, RS1000 or Rain/Freeze sensor RFS1000 to
restrict watering when moisture and/or temperature limits are met .
Note: If connecting an alternate make of rain sensor, ensure it pro-
vides normally-closed switch circuit operation.
IMPORTANT: If a rain sensor is not installed, the sensor
terminal jumper wire must remain in place, and the sensor
switch must remain in the Bypass position . If either of these
conditions are not met, automatic and manual operation will be
disabled .
1 . Insert the sensor cable through the bottom of the cabinet .
2 . Loosen the Sensor terminals and remove the jumper wire .
3 . Refer to the installation instructions provided with the Rain Sensor
and connect wires accordingly .
4 . Place the Sensor switch in the Active position .
Note: When the Rain Sensor is active, all watering
operations will be terminated and SEn (Sensor)
will be displayed (in the current time dial position).
