that could possibly cause interference of the signal. The transmitter should be mounted on any surface
where it will be exposed to unobstructed rainfall, but not in the path of sprinkler spray. Gutters are ideal
locations for the transmitter, and the specially designed bracket makes this installation as simple as
tightening the supplied thumbscrew onto the gutter lip once the transmitter is in place. However, the
transmitter can be mounted on any suitable surface using the enclosed screws. The unit should be mounted
in a vertical orientation with the antenna wire protruding straight down from the housing. Once again,
avoid an installation where the antenna wire comes in contact with any metallic object.
Prior to final placement, the transmitter should be tested once again be lightly pressing on the spindle for a
few seconds, the “System Off - Rain” light should illuminate. If the light is not visible to the installer,
simply set the controller to water a zone which is visible from the installation location and the activation of
the transmitter will shut off water flow to the “test” zone.
Note: If for some reason the location of the transmitter is not providing a valid signal to the receiver (this
could be due to an out of range installation or possible electric or sub-material interference), verify the
transmitter at close range and choose another mounting location as close as possible to the receiver/valve
controller.

The Wireless Rain Sensor is now fully functional and should provide you with years of worry free, water
saving service. When the rain sensor activates due to sufficient rainfall the “System Off - Rain” light will
illuminate on the receiver - there is no guessing when your rain sensor is active. Should it be necessary to
temporarily deactivate your Wireless Rain Sensor, it can be bypassed using the built in by-pass switch.
Simply press this switch once and the “System Off - Rain” light will go out until the next time the Wireless
Rain Sensor resets - all automatically.
When the “Battery Low” indicator light illuminates, this serves as a warning that the battery in the
transmitter is getting low. The battery should be replaced at the next convenient time - don't panic when
this happens, the Wireless Rain Sensor will function properly for some time after this indicator is present.
To replace the batteries, simply remove the transmitter from its bracket, slide the cover off the housing and
gently pull the circuit board partially out of the unit. The two batteries should then be accessible and can be
replaced.
