at a height at or above the receiver. If a north facing wall is not possible, choose a shaded area,
under an eve.
Direct sunlight and radiant heat sources will result in inaccurate temperature readings. Although
the sensor is weatherproof, it is best to mount in a well-protected area, such as an eve.
1.
Use a screw or nail to affix the remote sensor to the wall, as shown in Figure 6.
2.
Hang the remote sensor up on string, as shown in Figure 7.
Note:
Make sure the sensor is mounted vertically and not lying down on a flat surface. This
will insure optimum reception. Wireless signals are impacted by distance, interference (other
weather stations, wireless phones, wireless routers, TVs and computer monitors), and transmission
barriers, such as walls. In general, wireless signals will not penetrate solid metal and earth (down a
hill, for example).

Best Practices for Wireless Communication
Wireless communication is susceptible to interference, distance, walls and metal barriers. We
recommend the following best practices for trouble free wireless communication.
1.
Electro-Magnetic Interference (EMI)
. Keep the console several feet away from computer
monitors and TVs.
2.
Radio Frequency Interference (RFI).
If you have other 433 MHz devices and communication
is intermittent, try turning off these other devices for troubleshooting purposes. You may need to
relocate the transmitters or receivers to avoid intermittent communication.
3.
Line of Sight Rating.
This device is rated at 300feet line of sight (no interference, barriers or
walls) but typically you will get 100feet maximum under most real-world installations, which
include passing through barriers or walls.
4.
Metal Barriers.
Radio frequency will not pass through metal barriers such as aluminum siding. If
you have metal siding, align the remote and console through a window to get a clear line of sight.
The following is a table of reception loss vs. the transmission medium. Each “wall” or obstruction
decreases the transmission range by the factor shown below.
