As a general precaution, avoid placing or routing the temperature sensors or cable
near cables from other systems in order to decrease the possibility of picking up
disruptive signals and of interfering with other systems. Also, avoid placing and
routing sensors on or near metal gutters, metal windows, metal door frames, or
directly on a metal tower. These items may attract an electrostatic discharge (possi-
bly lightning) which could jump to the grounded cables and cause damage to the
sensors and/or console.
Note: Sensors and cables mounted to properly earth grounded metal masts and
towers may receive some protection from electrostatic discharge.
Using insulated standoffs (user supplied, or see Section 4) when routing cable helps
avoid these problems.
Mount the temperature sensor. It may be located anywhere, but in order to obtain an
accurate wind chill reading, it must be located outdoors. It should be mounted in a
location shielded from direct or reflected sunlight. Mounting the sensor under roof
eaves is appropriate in most applications. Avoid locations where ice and snow will
accumulate, or near heat radiating objects such as patios, sidewalks, reflective
siding, attic vents, etc.
Note: If desired, radiation shields (reflector type or aspirated) that will house the
temperature sensor are available from various sources. Contact Columbia Weather
Systems for more information if interested.
Once the temperature sensor has been placed, route the cable back to the console.
CAUTION - There may be electric wires in the wall. We recommend that you
shut off the electricity in the room(s) where you are drilling.
For best results:
a. drill a 3/8" hole though the wall
b. insert small plastic wall bushings (user supplied, or see Section 4) on either
side of the wall; and
c. thread the cable through the bushings. (It may be convenient to combine this
step with routing of the wind sensor cable. See “Mounting the Wind Sensor
Assembly,” page 27.)
Using a Phillips screwdriver, attach the three wires from the cable to the “Tempera-
ture” terminal post screws labeled “red,” “black,” and “bare” on the back panel.
