1.Hold the base of the rain gauge flat against the mounting surface then use a level to make sure the rain gauge (as it rests on the mounting surface) is hori- zontally level.

2.Use a pencil to trace the inside of the mounting holes on the base of the rain gauge to mark the screw locations.

3.Drill a small pilot hole (shallow and

slightly smaller in diameter than the sup- plied M3 17 screws) in the center of each marked location to guide the screws.

4.Hold the rain gauge against the mount- ing surface so the holes on the base are

aligned with the pilot holes, then thread the supplied M3 17 screws into each hole and use a Phillips screwdriver to tighten them.

INSTALLING THE OUTDOOR THERMO/HYGRO SENSOR

Selecting a Location

Select a mounting location for the outdoor thermo/hygro sensor that is within 10 feet of its solar transmitter.

Caution: To avoid false outdoor temperature and humidity readings and prevent damage to the sensor’s electronic components, do not place the sensor where it will be:

in direct or reflected sunlight

close to a surface that easily absorbs or reflects heat (such as a metallic surface or a window with reflective coating)

near hot or cold sources, such as a grill, stove or clothes dryer vent, or a heating or air conditioning unit

in an area where it might get wet

in an area where these substances are likely to be present in the air: salt, inor-

ganic gases (such as sulphur dioxide, chlorine, or ammonia), or organic gases (such as alcohol, glycol, aldehydes, and so on)

Connecting the Outdoor Thermo/ Hygro Sensor to a Solar Transmitter

1.Use a Phillips screwdriver to loosen the screws on the cover of the remaining solar transmitter, then remove the cover.

2.Install two AA batteries in the compart- ment according to the polarity symbols (+ and –) marked inside.

Cautions:

Use only fresh batteries of the re- quired size and recommended type.

Do not mix old and new batteries, dif- ferent types of batteries (standard, al- kaline, or rechargeable), or recharge- able batteries of different capacities.

3.Insert the outdoor thermo/hygro sen- sor’s modular plug into the modular jack inside the solar transmitter’s battery compartment.

4.Align the rubber gasket on the outdoor thermo/hygro sensor’s cord with the groove in the solar transmitter.

5.Replace the cover and secure it with its screws.

6.Mount the connected solar transmitter in a place that will be close to the outdoor thermo/hygro sensor.
