USER’S MANUAL

SECTION 1 INTRODUCTION

Congratulations on your purchasing the WMR112/112U Cable Free Weather Station. An all-purpose easy-to-use system, the WMR112/112U lets you monitor the following weather elements:

- Air temperature

- Relative humidity

- Barometric pressure

- Wind speed and direction

- Rainfall The WMR112/112U is also equipped with:

- RF calendar clock with daily alarm

- Weather forecast within 32 to 48 km (20- to 30-mile) radius

- Weather alarms

- Memory for maximum and minimum readings

- Touch-screen plus key button operation

STANDARD PACKAGE

The original WMR112/112U comes complete with the following:

- Main unit (WMR112/112U)

- Anemometer (WGR918N)

- Thermo-hygrometer (THGN228NX)

- Rain gauge (PCR918N)

- Baro-thermo-hygrometer (BTHR918N)

- 12V AC adapter

The rain gauge is powered by solar transmitter STR928 while the anemometer is powered by solar transmitter STR938.

The WMR112/112U can support up to seven different remote instruments. You can connect up to three optional thermo or thermo-hygro sensors to the system.

Optional items include:

- Thermo-hygro sensor (THGR228N/THGR238N)

- Thermo sensor (THR228N/THR238N)

Contact an authorized dealer for optional items.

SECTION 2 INSTALLATION

The WMR112/112U operates at 433MHz. No wire installation is required among units.

The WMR112/112U has an effective range of 100 meters in an open area. Position the units within the range and be sure the transmission path is clear of interference and obstacles.

Note: The anemometer, thermo-hygrometer and rain gauge should be installed outdoors and in locations that best measure the weather elements which the instruments are designed for. As for the barothermo-hygrometer, it must be installed indoors. If you have any optional thermo or thermo-hygro sensors, they can be installed outdoors or indoors.

THE ANEMOMETER

The anemometer measures wind speed and direction.

To install it,

1. Unscrew the solar transmitter STR938.

2. Plug in the connector of WGR918N into the solar transmitter as shown.

3. Secure the screws again.

4. Place the wind cup over the thinnest shaft on the anemometer’s T-bar.

5. Tighten the screw on the base of the wind cup.

6. Align the red markings on the wind vane’s shaft.

THE RAIN GAUGE

The rain gauge measures the total amount and rate of rainfall.

To install it:

1. Unscrew the solar transmitter STR928.

2. Plug in the connector of PCR918N into the solar transmitter as shown.

3. Secure the screws again.

7. With the aid of a compass, face the red marking south before mounting the anemometer.

8. Mount the anemometer and its solar transmitter safely in place.

The wind speed and direction window on the main unit should read 180° if the main unit is installed.

9. Press [RESET] of STR938 after installation.

THE THERMO-HYGROMETER

The thermo-hygrometer measures outdoor temperature and humidity. It uses two (2) UM-4 or “AAA” size batteries.

Follow these steps to install / replace batteries:

1. Remove the screws on the battery compartment.

RESET

2. Insert the batteries strictly according to the polarities shown

therein.

3. Replace the battery compartment door and secure its screws.

4. Press the [RESET] button.

4. Open the cover of the rain collector.

5. Remove the fiber tape from around the bucket assemblies.

6. Mount the rain gauge and its solar transmitter safely in place.

7. Put drops of water on the cross at the base on the rain collector to check the leveling.

Water stay at position 1 - 4 means the gauge is not leveled

8. Use metal ring to adjust the leveling of the rain collector if necessary.

9. Close the cover of the rain collector.

10. Press [RESET] of STR928 after installation.

THE SOLAR TRANSMITTERS

The solar transmitters make use of solar energy to power the instruments they are connected to. Two pieces of UM3 or "AA" sized batteries are needed as back-up power.

Note: It is recommended to insert two UM3 or “AA”-sized super lithium batteries for weather condition under 0 °C.

For the solar transmitters to function properly, make sure the solar receptors on the transmitters are exposed to sunlight and the connectors of the connection cable are securely plugged in.

THE BARO-THERMO-HYGROMETER

The baro-thermo-hygrometer measures the atmospheric pressure, temperature and humidity.

The sensor uses four UM4 or “AAA”-sized batteries.

To install it,

1. Insert alkaline batteries accordingly.

2. Mount the unit where you want to monitor the readings. Or you can make use of its table stand to place it on a flat surface.

THE MAIN UNIT

The main unit gives you all the readings and controls. It should be placed indoors.

The main unit is powered up by the 12V AC adapter.

To install it,

1. Position the main unit and other units within effective range (100 meters).

2. Insert four UM4 or “AAA”-sized alkaline batteries for backup purpose.

Stylus

Docking bracket

4. Connect the AC power adapter to the main unit and a wall socket.

DC 12V

5. Press the [RESET] button on the main unit to initiate operation. The main unit will start searching for signals for about four minutes.

Upon successful reception, the readings will be displayed. The main unit will update the readings at regular intervals.

TABLE-STAND

A docking bracket is provided so that you can rest the unit into it as well as for placement of the Stylus provided. The Stylus is designed to facilitate the touch-screen operation but you can also operate this function simply by touching the screen with your finger.

Caution: Do not press the screen too hard with the Stylus or it would cause damage to the display.

3. Mount the main unit safely in place. Or use its docking bracket to place it on a flat surface.

LOW-BATTERY WARNING

There are low-battery indicators [

] for the main unit, rain

gauge, baro-thermo-hygrometer, thermo-hygrometer and optional remote thermo and thermo-hygro sensors. Replace the batteries when the respective indicators light up.

Note: The readings collected from the thermo-hygrometer and any optional remote thermo and thermo-hygro sensors share the same display window. The “OUT” and remote channel will share the same low-battery indicator. When the battery level of the thermohygrometer is low, the low-battery indicator will turn on. If it is one of the optional remote sensors, the low-battery indicator will blink. To locate the channel in question, press the window to scan through all available devices. The low-battery indicator will stop blinking if the battery level is low for that one.
