then 4 minutes for the rain sensor. If not successful within 4 minutes, the thermo-hygro
sensor will stop looking for the other sensors.
5. Setup troubleshooting: If the sensor data fails to display for any of the outdoor sensors
within 10 minutes, ("- - -" is displayed), remove the batteries from all units for 1 minute
and start the Setup procedure again at Step 1.
MOUNTING THE SENSORS AND PLACEMENT OF THE WIRELESS DISPLAY:
IMPORTANT: Ensure that all of the sensor data can be received at the intended mounting
locations before you drill mounting holes. The wind and rain sensors have a wireless range of
200-feet & the thermo-hygro sensor has a wireless range of 200-feet. Keep in mind that the
ranges equate to an open air scenario with no obstructions. Each obstruction (roof, walls,
floors, ceilings, etc.) will reduce the range.
The thermo-hygro sensor measures outdoor temperature & humidity and collects the data
from the wind and the rain sensors. It sends all outdoor weather data to the wireless display,
so the thermo-hygro sensor must be within the 200-foot wireless range of the wireless display.
This allows the wind and rain sensors to be placed relative to the thermo-hygro sensor rather
than the wireless display. See Wireless Data Diagram above.
 The wind and rain sensors must be mounted within the 200-foot wireless range of the
thermo-hygro sensor and on the same side of the house.
 The wireless display must be within the 80-foot wireless range of the USB transceiver to
send weather data to the PC.
 In addition, 915 MHz sensors transmit better at a minimum mounted height of 6 feet.
