THE THERMO-HYGROMETER
GB
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.
RESET
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.
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 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.

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.
LOW-BATTERY WARNING
There are low-battery indicators [
] for the main unit, 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 or the optional remote sensors is low, the lowbattery indicator will blink. To locate the channel in question,
press the window to scan through all available devices. The lowbattery indicator will stop blinking if the battery level is low for
that one.

ABOUT RADIO CONTROLLED CLOCK RECEPTION
Whenever the WMR112A is brought within range of the radio
signal with its radio reception function activated, it will search for
the clock signal at a predefined time on each day while the manual
calendar clock settings will be overridden.
When the unit is new and just out of the box, synchronization with
the U.S.atomic clock can take upto 72 hours. The unit will receive
the mostdependable and interference free signal automatically
between Midnightand 4 AM.
While receiving the signal the radio reception indicator will blink.
A complete reception generally takes 2 to 10 minutes, depending
on the strength of the radio signal.
The indicator will stop blinking when the reception is complete.
The status of reception will be shown:
For best signal reception, place the unit away from other equipment
that emit RF or microwave signals such as TV's, radios, PC'sor
microwave ovens. Other causes for signal interference include
electrical power transmission towers, steel reinfoced concrete
construction, and/or metal siding.
After receiving the initial signal, updates are accomplished with
greaterease. Even though there are areas that may have more
difficulty in receiving a signal, the RF clock contains very accurate
quartz movement and will retain precise time even if a signal is
missed on a rare occasion.
To disable the radio reception function:
1. Press the RF calendar clock and alarm window.
2. Press and hold [
] to disable the function. The radio reception
indicator will disappear.
To enable the function again,
