HIGH/LOW TEMPERATURES
The High and Low recorded indoor temperatures and those of each chan-
nel will be automatically stored in memory. To display them,
1.
Select the channel to be checked.
2.
Press HIGH/LOW MEMORY Button (on front) once to display the High
temperature and again to display the Low temperature. The respective
indicators, High or Low will be displayed.
To clear the memory, press CLEAR. All segments of the display will light up
for two seconds. The display will return to the last screen with High and
Low temperature erased from memory. If you press HIGH/LOW MEMORY
Button (on front) now, the High and Low temperatures will have the same
values as the current temperature until different readings are recorded.
TROUBLE-SHOOTING
Disconnected Signals
If without obvious reasons the display for a particular channel goes blank,
press CHANNEL and HIGH/LOW MEMORY Button (on front ) to enforce an
immediate search. If that fails, check:
1.
The Remote Sensor of that channel is in place.
2.
The batteries on all units. If batteries are suspect, use fresh ones.
Note:
When the temperature falls below freezing point, the batteries of
outdoor units may freeze, lowering their voltage supply and effective range.
3.
The transmission is within range and path is clear of obstacles and
interference. Shorten the distance between the sensor and receiver
when necessary.
4.
If all else fails, use the reset button on both the remote and the
receiver and try again.
Transmission Collision
Signals from other devices, such as security systems and entry controls,
may interfere. This is normal and does not affect the general performance
of the product. The transmission and reception of temperature readings will
resume once the interference recedes.
Low Battery Warning
When it is time to replace batteries, the low battery indicator will show up
when the respective channel is selected. The battery level of the main unit
will be shown on the indoor temperature display when it is running low.
HOW TO RESET THE UNIT
This button located on the back of the receiver and sensor is only used
when the unit is operating in an unfavorable way or malfunctioning. Use a
blunt stylus to hold down the button. All settings will return to their default
values.
Table Stand or Wall Mount
The Receiver has a retractable stand, which when flipped open can support
the unit on a flat surface. Or you can close the stand and mount the unit on
a wall using the recessed screw hole.
The Remote Sensor comes with a wall-mount holder and a removable
stand. Use either to hold the unit in place.
MAINTENANCE/REPAIR
After final installation of the Model WMS Wireless Temperature Monitor, no
routine maintenance is required. A periodic check of system calibration is
recommended. These devices are not field repairable and should be
returned to the factory if recalibration or other service is required. After first
obtaining a Returned Goods Authorization (RGA) number, send the mater-
ial, freight prepaid, to the following address. Please include a clear descrip-
tion of the problem plus any application information available.

HOW TO CHECK REMOTE AND INDOOR TEMPERATURE
The indoor temperature is shown on the bottom line of the display. As the
Remote Sensor sites or channels, press CHANNEL to go from one channel
to another. The Kinetic Wave Display on the channel number indicates the
reception of that particular channel is in good order. If no readings are
received from one particular channel for more than two minute, blanks “- -
-” will be displayed until future readings are successfully found. Check that
the Remote Sensor is sound and secure. You can wait for a little while or
press CHANNEL and HIGH/LOW MEMORY button (on front) simultane-
ously to enforce an immediate search. No reading will be shown if no
Remote Sensor is assigned to that channel.
The temperature trend indicator on the screen shows the trend of readings
collected at that particular Remote Sensor site. Three trends: rising, steady,
and falling, will be shown. If the temperature goes above or below the
temperature measuring range of the Receiver or the Remote Sensor, “HHH”
or “LLL” will be displayed.
HOW TO USE TEMPERATURE ALARMS
The temperature alarms allow you to set the upper and lower limits of read-
ings for individual channels. The alarm will sound if a limit is exceeded. To
set alarm:
1.
Select the channel to be set.
2.
Press the HI/LO Switch (on back) for the upper (HI) or lower (LO) limit.
An “OFF” message will be displayed if the alarm for that limit is turned
off.
3.
Use the advance button (
) to set the Hi or Lo temperature. If this is
the first time you set the limits, the lower limit will start from -58˚F (50˚C)
and the upper limit 158˚F (70˚C). Otherwise, the reading will start from
the temperature last selected. Each press on the button will increase
the temperature by one degree. Holding down the button will raise the
reading by five degree increments.
4.
Press TEMP AL ON/OFF button to switch off the “OFF” message. The
set limit will be displayed.
5.
Press HI/LO button to set another limit or return to normal display. The
respective HI, LO or both indicators will light up to signify the status of
the alarm.
When the alarm goes off, the display will switch to the respective channel
with the display flashing. If undisturbed, the alarm will sound for one
minute. Press any key to mute the alarm momentarily. The alarm will sound
again if the temperature still exceeds the set limit. To disable an alarm alto-
gether, select the channel and use TEMP AL ON/OFF to turn it off. If you
have set the upper and lower temperatures for more than one channel and
limits are exceeded, the alarm will go off with the display switching from
one channel to another at five second intervals.
HOW TO SELECT THE UNITS OF MEASURE
Use the ˚C/˚F slide switch on the receiver to select unit of measure. Select
˚C for Celsius and ˚F for Fahrenheit.
Note:
The Remote Sensor temperature units of measure are controlled by
the Receiver. Whatever the display units of the Remote Sensors are, they
will be automatically converted and displayed to the chosen measurement
of the Receiver.
HOW TO READ THE KINETIC WAVE DISPLAY
The kinetic wave display shows the signal receiving status of the Receiver.
These are three possible forms.
