Installing the Sensor Module
1. Adjust the sensor module to the preferred rainfall threshold activation point.
The settings, provided in metric on one side of the cap and U.S. standard on
the other, include 3mm, 6mm, 12mm and 19mm. The factory setting is 6mm
and is generally a good starting point. The 3mm setting is not
recommended
for high humidity or foggy locations. To adjust, turn the cap to align the
stationary pin with the vertical slot. Guide the cap to the preferred slot
position, then turn it just enough to engage the pin.
2. To install the sensor module on a rain
gutter, position the Quick Clip bracket
on the outer edge of the gutter and
secure by tightening the thumb screw
(Figure 12). Use the provided stainless
steel screws when installing the sensor
on a solid structure, such as a fence or
the side of a roof. See Figure 13.
Note: For optimum signal strength,
the antenna wire should hang straight
down. Ensure the antenna is not in
contact with any metal objects .
