HOW THE RAIN SENSOR FEATURE WORKS
The Total Control is equipped to operate with an optional rain sensing device, commonly
called a “Rain Switch,” to prevent automatic watering during rain.
The rain switch is a simple device, typically installed on a roof overhang or stationary
structure exposed to rainfall and full sun, and shielded from irrigation spray.
A two-position Sensor switch (see item 12 on page 3) is provided to enable you to easily
bypass operation of the rain switch at any time. If you choose to disregard rain switch
input, place the SENSOR switch in the Bypass position. To enable rain switch operation,
place the Sensor switch in the Active position. When the dial is in the RUN position,
SEN will be fl ashing if the sensor switch is open.
NOTE: A jumper wire is installed across the sensor terminals. The jumper must be
removed when the rain switch wires are connected.
See page 23 for sensor installation procedure.
NOTE: If using the Climate Logic Automatic Weather-Following System, do not connect a
rain sensor into the terminals. Leave the jumper wire in place.

Automatic Weather-Following System
The Irrritrol Climate Logic system consist of a wireless weather sensor, to be mounted
outdoors in the yard or graden, and a receiver module to be plugged into the controller
(See item 29 on page 3). Weather data is automatically sent to the module and it will
automatically modify the controller program’s water budget percentage to increase or
decrease watering accordingly. Follow the installation and setup instructions that come
with the Climate Logic system.
NOTE: When using the Climate Logic Automatic Weather-Following System, do not
connect an additional rain sensor to the controller. Leave the jumper wire in the Rain
Sensor terminals.
