MODEL: WMR112A
USER’S MANUAL
SECTION 1 INTRODUCTION
Congratulations on your purchasing the WMR112A Cable Free
Weather Station. An all-purpose easy-to-use system, the WMR112A
lets you monitor the following weather elements:
- Air temperature
- Relative humidity
- Barometric pressure
The WMR112A 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
PACKAGE
The original WMR112A includes the following:
- Main unit (WMR112A)
- Baro-thermo-hygrometer (BTHR968)
- Thermo-hygrometer (THGR268)
- 12V AC adapter
The WMR112A 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:
- Anemometer (WGR968)
- Rain gauge (RGR968)
- Thermo sensor (THR238/THC268)
- Outdoor Thermo-hygrometer(THGR968)
Contact an authorized dealer for optional items.
SECTION 2 INSTALLATION
The WMR112A operates at 433MHz. No wire installation is required
among units.
The WMR112A has an effective range of 300 feet in an open area.
Position the units within the range and be sure the transmission
path is clear of interference and obstacles.
Note: The thermo-hygrometer should be installed outdoors and in
locations that best measure the weather elements which the
instruments are designed for. As for the baro-thermo-hygrometer,
it must be installed indoors. If you have any optional thermo or
thermo-hygro sensors, they can be installed outdoors or indoors.
THE THERMO-HYGROMETER
The thermo-hygrometer measures outdoor temperature and
humidity. It uses two (2) UM-3 or “AA” size batteries.
Follow these steps to install / replace batteries:
1. Remove the screws on the battery compartment.
2. Assign a channel to the sensor by changing the channel switch
in the battery compartment of the remote sensor.
3. Select the unit of measurement for the temperature display on
the degrees C and degrees F slide switch
4. Insert the batteries strictly according to the polarities shown
therein.
5. Press the [RESET] button.
6. Replace the battery compartment door and secure its screws.
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
(300 feet).
2. Insert four UM4 or “AAA”-sized alkaline batteries for backup
purpose.
