6.11 Best practices for wireless communication
Note:
To ensure proper communication, mount the remote sensor(s) upright on a vertical surface such
as a wall. Do not lay the sensor flat.
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 display several feet away from
computer monitors and TVs.
2. Radio Frequency Interference (RFI): If you have other 433/868/915 MHz devices and
communication is intermittent, try turning off these other devices. You may need to
relocate the outdoor units or receivers to avoid intermittent communication.
3. Line of Sight Rating: This device is rated at 300 feet line of sight (no interference,
barriers or walls) but typically, you will get 100 feet 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 outdoor unit and display through a window to
get a clear line of sight.
The following is a table of the transmission medium vs.reception loss. Each “wall” or obstruction
decreases the transmission range by the factor shown below.
7 Operation
Note:
Because of the default settings already determined by the manufacturer, it may not be necessary
for the majority of users to perform – except the relative air pressure (see further down) - any
further basic settings. Changes, however, can be easily made.
For basic settings, the following menu is started by touching the touch screen in the desired
display area.
The basic settings can now be performed in the following successive order:
Note:
The setting procedure can be exited at any time by touching any other function area (except “+”,
“-” or “ON/OFF”).
