4.3 Outdoor Channel Selection and Scroll Mode

Press the CHANNEL/+ button to switch the display between remote sensors 1 through 8, and scroll

mode

. In scroll mode, all of the remote sensors will be displayed in five second intervals.

4.4 Temperature Units of Measure

The default temperature units of measure are degrees Fahrenheit. To toggle between degrees Celsius

and degrees Fahrenheit, press and hold the MIN/MAX button for 3 seconds.

4.5 Sensor Search Mode and Resyncing the Sensors

If any of the sensor communication is lost, dashes (--.-) will be displayed on the screen. To reacquire

the signal:

1. If a specific channel is lost, press the CHANNEL/+ button to display this channel, then Press

and hold the CHANNEL/+ button for 3 seconds, and the remote search icon

constantly displayed for up to 10 minutes. Once the signal is reacquired, the remote search

icon

will turn off, and the current values will be displayed.

2. If new sensors are added, subtracted, or multiple sensor channels are lost, Press and hold the

CHANNEL/+ button for 5 seconds, and the remote search icon

displayed for up to 10 minutes. Once the signal is reacquired, the remote search icon

will turn off, and the current values will be displayed.

4.6 Best Practices for Wireless Communication

Note: To insure proper communication, mount the remote sensor 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 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 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 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.
