How To Set Up Your Wireless Thermometer

5

• Place the receiver unit as close as possible to
the remote unit. This will ensure easy synchron­ization between the transmission and reception of
signals as you set up your wireless thermometer.
After set up is completed, position the receiver
unit and remote unit within effective transmission
range which, in usual circumstances, is 100 feet.

Note: The effective range is vastly affected by the
nearby building materials and where the receiver
and remote units are positioned. Try various set ups
for the best results. Shorten the distance between
receiver and remote units when necessary.

Important: Though the remote unit is weather

proof, it should be placed away from direct

sunlight, rain, snow and should never be

submerged in water. Also please note that

below 32ºF / 0ºC the LCD readout on the remote

unit may begin to fail display. When this

happens the remote will still transmit correct

temperature readings to the receiver unit but

can not be viewed at the remote location. When

the temperature rises above 32ºF / 0ºC the

display will begin to function normally again.

Battery Installation

6

For the initial installation, insert the
batteries into the receiver unit first,
then the remote unit:

Receiver

1. Lift off the battery compartment cover, located

on the back of the unit.

2. Insert 2 AA alkaline batteries as indicated by
the polarity symbols marked inside the battery
compartment.

3. Replace the battery compartment cover.

Remote

1. Lift off the bracket stand, located on the back
of the unit, to access the battery compartment
cover.

2. Remove the 4 screws that secure the battery
compartment cover and then remove the
cover.

3. Select the Channel setting by sliding the CH
switch to Channel 1 to register the first
sensor, included in this package.

Note: Maximum 3 remote sensor units can be

registered. Should you purchase one or two additional
remote units (Model 1459, sold separately) to expand
your thermometer monitoring capabilities to multiple
locations, slide the CH switch to Channel 2 to register the
second sensor and select Channel 3 to register the third
sensor.

4. Insert 2 AA alkaline batteries as indicated by
the polarity symbols marked inside the
battery compartment.

How to Read Temperatures and Other Displays

8

Important: When the temperature falls below
freezing point, the batteries of outdoor units may
freeze, lowering their voltage supply and effective
range. Use Lithium batteries to insure operation
below 10°F (-12° C).

5. Press the F/C button to select the desired

temperature measurement scale.

6. The remote will automatically send a

transmission to the receiver. The red LED
Indicator light will flash when a signal is
transmitted. Remote unit temperature
updates will then be transmitted at 2 minute
30 second intervals.

Note: If dashes are still displayed on the
receiver unit, press the TM button to send a
transmission.

7. Replace the battery compartment cover,

replace and tighten screws and reattach the
bracket stand.

• The top half of the receiver display will show

the temperature, humidity and heat index of
one remote unit (set to Channel 1). If more
than one remote unit is set, simply press the
Channel button on the receiver unit until it
correlates to the designated channel of the
second /third remote location(s).

How to Read Temperatures and Other Displays (continued)

9

•The bottom half of the receiver display will show

indoor temperature and humidity at its location.

•The Temp Trend/Humidity Trend graphs on top &

bottom of the receiver unit display show an Up
symbol when the temperature increases more
than 1 degree (humidity 3%), a Steady symbol
when temperature change is less than 1 degree
(humidity less than 3%), or a Down symbol
when the temperature decreases more than 1
degree (humidity 3%) for 60 minutes in the
remote and receiver locations.

•To view high/low daily temperatures (Max/Min

Memory) press Mode button on the receiver unit
(see Features & How to Access Functions section
of this manual).

•The Heat Index combines temperature and

relative humidity for an “apparent” temperature,
or how hot it actually feels. As the heat index
rises, so do the risks of heat disorders.

Trouble-Shooting

Disconnected Signals

• If the receiver unit does not receive a

transmission from a remote unit channel for 1
hour, the display will show dashes. To correct this
problem:

1. Go to the remote location of that channel to

check that the unit is properly positioned,
within the appropriate transmission range.

2. If new batteries are faulty on the initial

installation, install fresh batteries. If you did
not notice the Low Battery icon warning and
the product performed correctly after initial
set up, the batteries have lost their charge.
Replace batteries (see steps for Battery
Installation in the How To Set Up Your
Wireless Thermometer section of this
manual.)

3. Check to make sure the transmission path is

clear of obstacles and interference.

Battery Replacement (continued)

Note: When replacing batteries in the remote unit,
remember to clear the corresponding channel of
the receiver unit by 1) pushing the channel button
to select the respective channel; 2) holding the
channel button for 3 seconds to clear the
registration.

• When the batteries on the receiver unit or the

remote unit are low, the Low Battery Indicator
icon will light up on the relevant displays.
Follow the steps for Battery Installation in the
How To Set Up Your Wireless Thermometer
section of this manual.
