Detailed Setup Guide

hygro sensor, but direct rain must be avoided.

I. BATTERY INSTALLATION (When one thermo-hygro sensor is being used)

1.First, insert the batteries to the thermo-hygro sensor (see “A. thermo-hygro sensor” below).

2.Within 2 minutes of powering up the sensor, insert the batteries to the Wireless Weather Station (see “B. Wireless Weather Station” below). Once the batteries are in place, all segments of the LCD will light up briefly. Following the indoor temperature and the time as 12:00 will be displayed. If they are not shown in LCD after 60 seconds, remove the batteries and wait for at least 60 seconds before reinserting them. Once the indoor data is displayed user may proceed to the next step.

3.After the batteries are inserted, the Weather Station will start receiving data signal from the sensor. The outdoor temperature and humidity should then be displayed on the Weather Station. If this does not happen after 2 minutes, the batteries will need to be removed from both units and reset from step 1 and the signal reception icon is no longer shown.

5.Press and release the SET/CH button to exit the SET UP mode.

Note: If no buttons are pressed for 10 seconds, the Wireless Weather Station will automatically return to the normal display.

II. FEATURES

A. MINIMUM AND MAXIMUM TEMPERATURES AND HUMIDITY

1.Press and release the MIN/MAX button, “MIN” appears at the bottom of the LCD and the recorded minimum temperatures and humidity are displayed.

2.Press and release the MIN/MAX button again to view maximum recorded temperatures and humidity. “MAX” appears at the bottom of the LCD and the maximum temperatures and humidity are displayed.

3.Press and release the MIN/MAX button once more to return to the current temperatures and humidity.

B. RESETTING THE MINIMUM AND MAXIMUM TEMPERATURES AND HUMIDITY

To reset both the minimum and maximum temperatures and humidity-press and hold the MIN/MAX button for 5 seconds.

A.THERMO-HYGRO SENSOR

1. Remove the Battery Cover.

2. Observing the correct polarity, install 2 “AA” Alkaline Batteries-make sure they do not spring free, or start-up problems may occur. Replace the Battery Cover.

B. WIRELESS WEATHER STATION

Note: After the batteries are installed, DO NOT press any buttons. This may interfere with the signals, causing temperatures to register incorrectly.

1.Remove the Battery Cover on the back of the Wireless Weather Station.

2.Observing the correct polarity, install 2 “AAA” Alkaline Batteries.

C.ADDING ADDITIONAL REMOTE SENSORS (OPTIONAL)

The WS-7220U-IT is able to receive signals from 2 additional thermo-hygro sensors.The following are instructions for the set-up of thermo-hygro sensor units with the WS-7220U-IT. These extra sensors can be purchased through the same dealer as this unit.

1.Remove all the batteries from the receiver and sensor(s) and wait 60 seconds. During these 60 seconds, press any button 20 times to discharge any excess power.

2.Insert the batteries to the first thermo-hygro sensor.

3.Within 2 minutes of powering up the first sensor, insert the batteries to the Weather Station. Once the batteries are in place, all segments of the LCD will light up briefly. Following the indoor temperature and the time as 12:00 will be displayed. If they are not shown in LCD after 60 seconds, remove the batteries and wait for at least 60 seconds before reinserting them.

4.The outdoor temperature and humidity from the first sensor (channel 1) should then be displayed on the Weather Station. If this does not happen and the signal reception icon is not shown, after 2 minutes, the batteries will need to be removed from both units and reset from step 1.

5.Insert the batteries to the second sensor as

3.Replace Battery Cover.

4.Wait 15 minutes before pressing any buttons.

Sensor signal reception icon*

*When the signal is successfully received by the Weather Station, the icon will be switched on. (If not successful, the icon will not be shown in LCD) So the user can easily see whether the last reception was successful (icon on) or not (icon off). On the other hand, the short blinking of the icon shows that a reception is being done now.

•If the signal reception is not successful on the first frequency (915MHz) for 45 seconds, the frequency is changed to 920MHz and the learning is tried another 45 seconds. If still not successful the reception is tried for

soon as the outdoor temperature and humidity readings from the first sensor are displayed on the Weather Station.

NOTE: You must insert the batteries into the second sensor within 30 seconds of reception of the first sensor.

6.The outdoor temperature and humidity from the second sensor and the “channel 2” icon should then be displayed on the Weather Station. If this does not happen after 2 minute, the batteries will need to be removed from all the units and reset from step 1.

7.Insert the batteries to the third sensor as soon as the “channel 2” icon and outdoor data are displayed on the Weather Station. Then within 2 minutes, the channel 3 outdoor data from the third sensor will be displayed and the channel icon will shift back to “1” once the third transmitter is successfully received. If this is not happen, user shall restart the setting up from step 1.

NOTE: You must insert the batteries into the third sensor within 30 seconds of reception of the second sensor.

IMPORTANT: Transmission problems will arise if the setting for multiple sensors is not followed as described above. Should transmission problems occur, it is necessary to remove the batteries from all units and start again the set- up from step 1.

45 seconds on 910MHz. This will also be done for re-synchronization.

C.SELECTING 12 OR 24 HOUR TIME DISPLAY

1.Press and hold the SET/CH button for about 5 seconds.

2.“12h” will begin to flash in the TIME section of the LCD

3.Press the MIN/MAX/+ button to toggle between “12h” and “24h” time.

Note:

•Selecting 12 hour time will automatically select ˚F as your temperature unit.

•Selecting 24 hour time will automatically

select ˚C as your temperature unit.

4.Press and release the SET/CH button again to enter Time Setting.

D. TIME SETTING

1.After exiting the 12/24 Hour Setting, the hour will begin flashing in the time display.

2.Press and release the MIN/MAX/+ button to select the desired hour.

Note: PM will appear to the left of the time display for PM hours. For AM hours, that area will remain blank.

3.Press and release the SET/CH button again, and the minutes will begin to flash.

D. VIEWING AND OPERATING WITH MULTIPLE REMOTE SENSOR UNITS

1.To view the temperature of a different thermo- hygro sensor unit, press and release the SET/ CH button. A shift from one “boxed” number to the next should be observed on the right side of the OUTDOOR LCD.

2.To view the Minimum/Maximum temperature & humidity: first select from which thermo- hygro sensor to read data (indicated by the “boxed” number). Pressing and releasing the MIN/MAX button will toggle through the minimum and maximum indoor temperature, and the minimum and maximum outdoor temperature and humidity.

3.To reset the Minimum/Maximum readings, press and hold the MIN/MAX button for 5 seconds.

III. MOUNTING

Note: To achieve a true temperature reading, avoid mounting in direct sunlight. We recommend that you mount the thermo-hygro sensor on an outside North-facing wall (under the eve of a house is ideal). The sending range is 330 feet; obstacles such as walls, stucco walls, concrete, and large metal objects will reduce the range. Place the Wireless Weather Station and thermo- hygro sensor in their desired locations before permanently mounting.
