Mounting the Outdoor Thermo/ Hygro Sensor

1.Hold the sensor’s mounting bracket flat against the mounting surface and trace the inside of the pilot holes with a pencil to mark the screw locations.

2.Drill a small pilot hole (shallow and

slightly smaller in diameter than the sup- plied M3 ⋅ 12 screws) in the center of each marked location to guide the screws.

3.Hold the bracket against the mounting surface so the bracket and pilot holes

are aligned, then thread one of the sup- plied M3 ⋅ 12 screws into each hole and tighten them with a Phillips screwdriver.

4.To mount the sensor on the bracket, press the grooved area on the sensor against the clip-arm on the bracket so it pops into place. Then press the sensor’s modular cord into the guides on the bracket’s arm and base.

INSTALLING THE INDOOR THERMO/HYGRO/BARO SENSOR

Selecting a Location

Set the thermo/hygro/baro sensor indoors on a flat surface (such as a desk or counter) using its built-in stand, or mount it on an indoor wall.

Caution: To avoid false atmospheric pres- sure, temperature, and humidity readings, do not place the sensor where it will be:

•outdoors

•in direct sunlight

•in water or in a location where it is likely to get wet

•on or close to a surface that easily absorbs or reflects heat (such as a win- dow or metal surface)

•near hot or cold sources, such as stoves, heating and air conditioning vents, and radiators.

Before mounting the thermo/hygro/baro sen- sor, install its batteries.

1.Slide the battery compartment down to remove it.

2.Install four AAA 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.Replace the cover.

Mounting the Thermo/Hygro/Baro Sensor on a Wall

To mount the thermo/hygro/baro sensor on a wall, you need a screw (not supplied) with a head that fits into the keyhole slot on the back of the sensor.

1.Drill a hole in the wall at the desired mounting location.

2.Thread a screw into the wall until the head extends about 1/4 inch from the wall.

3.Position the keyhole slot over the screw and slide the sensor down to secure it.
