In this time the intelligent weather station and remote
temperature/humidity sensor will begin to communicate with each other
and the display will show the temperature/humidity, outdoor
temperature/humidity. If the intelligent weather station does not display
all information after the 15 minutes, please retry the set up as stated
above. After all information has been displayed for 15 minutes you can
place your sensors outdoors and set your time.
Important Notes on Set-up and Operation
The remote temperature/humidity sensor should be placed in a
dry, shaded area.
Fog and mist will not harm your remote temperature/humidity
sensor but direct rain must be avoided.
The remote temperature sensor should be placed in a dry,
shaded area. The remote temperature sensor has a range of 330
feet. Keep in mind that the 330 feet is in open air with no
obstructions and that radio waves DO NOT curve around objects.
Actual transmission range will vary depending on what is in the
path of the signal. Each obstruction (roof, walls, floors, ceilings,
thick trees, etc.) will effectively cut signal range in half.
Example: A wireless weather station receiver with a 330 feet
range is mounted on an interior wall, so that the signal has to pass
through one interior wall, one exterior wall, and across the 10 foot
width of the room between the 2 walls. The first wall will reduce
the range to 165 feet, and the second wall will reduce the range to
87 feet. Factoring in the 10 foot room, this leaves a maximum of
77 feet of remaining signal range.
This allowance is typically enough for a frame wall with non-
metallic siding; however certain materials can reduce range even
further. Metal siding, stucco, and some types of glass can reduce
signal range by as much as ¾ or more, compared to the ½
reduction typical of most obstructions. It is possible to receive a
signal through these materials, however maximum range will be
much less due to their tendency to absorb or reflect a much larger
portion of the sensor’s signal.
The remote temperature/humidity sensor transmits a signal every
4 seconds – with variations during updating periods. After the
batteries have been installed, the intelligent weather station will
search for the signal for the duration of 45 seconds. If there is no
temperature or humidity reading in the OUTDOOR LCD after 5
minutes, make sure the units are within range of each other, or
repeat the battery installation procedure.
