The wireless sensor system is comprised of a programmable, weather-resistant receiver module and a sensor module with built-in transmitter. The receiver installs next to the irrigation controller and connects to the controller’s 24 Vac power source and sensor input terminals (if equipped)

or splices directly into the irrigation valve common wire. The sensor module is installed within range of the receiver in a location that best represents the landscape’s sun/shade exposure and can provide reliable communication from the sensor to the receiver.

Once activated by preset rain or low temperature levels (Rain/Freeze model only), the sensor communicates to the receiver via ultra high-frequency radio signal. The receiver responds by placing the controller’s automatic watering schedule on hold or by simply opening the valve common circuit to prevent sprinkler valve operation. When watering is once again needed, the sensor system automatically resets, allowing automatic irrigation to resume.

More than just an accurate rain switch, the wireless sensor system actually adapts to your landscape with the simple, yet sophisticated Water Conservation feature. Just choose the conservation level that corresponds to your landscape soil type and the sensor location.

A dry-out period, adjusted for actual rainfall duration, is automatically placed after the sensor system resets to effectively delay automatic watering until it is actually needed.

Other standard features include a Smart BypassTM button that gives you manual control over the sensor system with a single touch, system status indicators to see at glance that your sensor system is active and watering is on hold, watering delay to postpone automatic watering from

1 to 5 days, air temperature displayed for Rain/Freeze sensors and even a Fail-safe mode to allow irrigation in case the sensor system is not performing properly.
