WEATHER ECHO AND WEATHER ECHO PLUS INSTALLATION MANUAL The Weather Echo and Weather Echo Plus displays act as radio receivers showing weather data transmitted by any “DavisTalk“compatible host station. When transmitted by a host station with the appropriate sensor installed, the Weather Echo and Weather Echo Plus can show the data in the table below.
The Echo and Echo Plus communicate on one of 8 different ID codes. This allows you to operate multiple systems in the same geographic area. The receiver operates on a low power frequency that does not require you to have a FCC license.
L OCATING THE W EATHER E CHO /W EATHER E CHO P LUS Try to position the Echo or Echo Plus display and the host station transmitter as close as possible for best results. The typical maximum ranges are as follows: ✦ Through walls and ceilings: 100 to 200 feet (30 to 60 m) ✦ Through trees and foliage: 100 to 200 feet (30 to 60 m) I NSTALLING THE W EATHER E CHO /W EATHER E CHO P LUS The Echo and Echo Plus comes supplied with a 3 Volt Lithium battery. To install the battery: 1.
Attaching the Power Adapter The Weather Echo Plus comes with a 110 VAC power adapter. To attach the power adapter: 1. Insert the power adapter plug into the jack at the side of the unit. 2. Remove the backing paper from the cable tie mount and affix to the back of the unit as shown below. (This prevents the power adapter plug from accidentally unplugging.
M OUNTING THE W EATHER E CHO AND W EATHER E CHO P LUS There are two ways you can position the display: ✦ On a shelf or other horizontal surface. ✦ On a wall mounting bracket. To sit on a horizontal surface: ✦ Slide the metal stand into the groove at the back of the display unit. Adjust the stand up or down to hold the display at a comfortable viewing angle. Remove the stand to sit the display vertically on a shelf.
To mount on a wall using a mounting bracket: You need the following: ✦ A mounting bracket (supplied) ✦ Two #6 x 1/2” (1.7 cm) flat head screws (supplied) ✦ A small Phillips-Head screwdriver 1. Remove the metal stand if attached. 2. Fasten the mounting bracket to the mounting location using the two 1/2” (1.7 cm) screws, making sure to position the bracket with the thumb grip on the left.

The Weather Echo and Weather Echo Plus display has 4 keys: MODE, SET, - and + . Use each key as follows: ✦ MODE—to select (in a sequential round robin fashion) in Modes 1 and 3. ✦ SET—to set data that alternate in Mode 1 and 2 and for data entry in Mode 3. ✦ “-”—to scroll backward in Mode 1 and 2 and to decrement in Mode 3. ✦ “+”—to scroll forward in Mode 1 and 2 and to increment in Mode 3. Use each mode as follows: ✦ Use Mode 1 to view the current weather data as shown below.
✦ Use Mode 2 to view the high and lows for the current day and the previous 7 days. HIGHS TEMPERATURE N ¡ OUT ¡ IN HUMIDITY MPH W ¡ E . . DATE RAIN . S in TEMPERATURE LOWS ¡ OUT ¡ IN HUMIDITY ¡ . . DATE RAIN . in MODE 2 SCREENS ✦ Use Mode 3 to set up the time, date, transmitter ID, and rainfall total, to calibrate rainfall, barometric pressure, and to choose your hemisphere. Enter ID Code here MONTH DAY ID CODE YEAR TIME . . TOTAL RAIN .
Interpreting the Forecast Icons The Echo and Echo Plus can display forecast when they receive data from a weather station with a built-in barometer. You can view forecast icons when a minimum of three hours of weather data is stored in memory. The forecast is derived from barometric readings, three-hour barometric trends, the prevailing wind direction, the season, the hemisphere, and whether or not it is raining. To get a more accurate forecast, your weather station should include a rain gauge.
S ETTING UP THE W EATHER E CHO /W EATHER E CHO P LUS Before you begin to read data from your display, you need to set up: ✦ The display preferences ✦ The current information You also need to calibrate for barometric pressure and rainfall. Setting up the Display Preferences If you have a US model, the default display unit for rainfall is inches. If you have an OV model, the default display unit for rainfall is millimeters.
Note: In the Highs and Lows mode, press the MODE key once to change to the home screen. In the Set-up mode, press and hold the MODE key for 4 seconds to return to the home screen. To set the unit to power saving mode: ✦ Press and hold the + and - keys simultaneously for 4 seconds in Mode 1. A bull’s-eye appears in the bottom left corner of the display, to indicate the unit is in power saving mode.
To set the date: 1. Press the MODE key to change from Time to Day. The first of the day digits flashes. Flashing digit MONTH DAY ID CODE YEAR TIME . . TOTAL RAIN . in SETTING THE DATE 2. Input the correct digit value using the + or - key. 3. Press the SET key to accept the value and move on to the next digit. 4. Repeat steps 2 and 3 to input the remaining day digit. 5. Press the MODE key to change from Day to Month. 6. Repeat steps 2 and 3 to input the remaining month digit. 7.
To add past rainfall totals: 1. Press the MODE key to change from ID Code to Total Rain. 2. Input the first digit value using the + or - key. MONTH DAY ID CODE YEAR TIME . . TOTAL RAIN . in Flashing digit ADDING PAST RAINFALL TOTALS 3. Press the SET key to accept the value and move on to the next digit. 4. Repeat steps 2 and 3 to input the remaining digits. Next, you need to input barometric data, select the correct hemisphere for forecasting, and calibrate the rain gauge.
To select the hemisphere: 1. Press the MODE key to change from Barometer to Hemisphere. Enter hemisphere here Hemisphere N=0 S=1 . . RAIN BAROMETER in . in SELECTING THE HEMISPHERE 2. Input a value of 0 for the Northern hemisphere and 1 for the Southern hemisphere using the + or - key. Note: If you do not specify a hemisphere, the default hemisphere is the Northern hemisphere. Hemisphere is used in the weather forecasting feature of your display. To calibrate the rain gauge: 1.
V IEWING C URRENT W EATHER D ATA You can view the following current weather data automatically while in Mode 1: ✦ Outside temperature ✦ Inside temperature ✦ Wind speed ✦ Wind direction ✦ Daily rain alternating with total rain N ¡ TEMPERATURE OUT MPH W ¡ IN ¡ E WINDCHILL TIME S . . TOTAL RAIN .

Reading the Wind Direction There are eight wind direction arrowheads. A single arrowhead turns on when the wind is within ±12° of the direction of the arrowhead. When the wind is in the middle 21° between two arrowheads, both arrowheads turn on. The wind direction is halfway between these two arrows This wind direction is South N N MPH W E MPH W S E S WIND DIRECTION DISPLAY V IEWING H ISTORICAL W EATHER D ATA In Mode 2, you can view historical highs and lows as far back as seven days.
