The Hard-wired Rain and Freeze Sensor prevents your automatic sprinkler system from watering during a storm, helping to conserve water. The rain sensor is adjustable to accommodate rainfall from .31 cm (1/8 inch) to 2.54 cm (1 inch). The freeze sensor reduces the risk of standing water in your pipes during freezing conditions, so pipes don't rupture or crack.
RAIN DELAY: No more watering during rain or freezing conditions.
ADJUSTABLE RAIN SENSITIVITY: Choose how much rainwater your sensor collects from .31 cm (1/8 inch) to 2.54 cm (1 inch) of precipitation before it signals your timer to turn off the sprinklers.
INCLUDES: 9.14 m (30 feet) of wire to connect your sensor to your sprinkler timer.
DIGITAL FREEZE SENSOR: Prevents your sprinkler system from watering in freezing conditions, reducing damage and costly repairs.
UNIVERSAL DESIGN: Works with most existing sprinkler systems.
MOUNTS SECURELY: Using 1.27 cm (1/2 inch) female pipe thread, PVC pipe using included slip-to-male pipe thread adapter, rain gutters, or mounting bracket for flat surfaces.
