GETTING STARTED

POWER

Insert batteries before first use, matching the polarity (+

and -).

NOTE Install batteries in the remote sensor before the

main unit. Press RESET after each battery change. Do

not use rechargeable batteries. We recommend that you

use alkaline batteries with this product for longer usage

and lithium batteries in temperatures below freezing.

UNIT LOCATION

Main Indoor temperature area

Remote Outdoor temperature area

REMOTE SENSOR

The sensor collects temperature readings approx. every

40 seconds and sends them to the main unit. The main

unit can collect data from up to 3 sensors.

To set up the sensor:

1. Remove the screws from the battery door.

2. Insert the batteries, matching the polarity (+ / -).

3. Select a channel. Make sure you use a different

channel for each sensor.

4. Place the sensor near the main unit. Press RESET

on the sensor.

5. Simultaneously press CHANNEL and MEM on the

main unit to initiate signal sending between the

sensor and main unit.

6. Close the battery door and secure the screws.

7. Place the sensor in the desired location using the

table stand or wall mount.

For best results:

• Place the sensor out of direct sunlight and moisture.

• Do not place the sensor more than 30 meters

(100 feet) from the main (indoor) unit.

• Position the sensor so that it faces the main (indoor)

unit, minimizing obstructions such as doors,

walls, and furniture.

• Place the sensor in a location with a clear view to

the sky, away from metallic or electronic objects.

• Position the sensor close to the main unit during

cold winter months as below-freezing temperatures

may affect battery performance and signal

transmission.

The transmission range may vary depending on many

factors. You may need to experiment with various locations

to get the best results.

Standard Alkaline batteries contain significant amounts of

water. Because of this they will freeze in low temperatures

of approximately -12°C (10°F). Disposable Lithium batteries

have a much lower threshold for temperature with an

estimated freezing range of below -40°C (-40°F).

Wireless ranges can be impacted by a variety of factors

such as extremely cold temperatures. Extreme cold may

temporarily reduce the effective range between the sensor

and the base station. If the unit’s performance fails due to

low temperature, the unit will resume proper functioning

as the temperature rises to within the normal temperature

range (i.e. no permanent damage will occur to the unit due

to low temperatures).

SENSOR DATA TRANSMISSION

Data is sent from the sensor(s) every 40 seconds. The

reception icon in the outdoor temperature area shows the

status.

ICON DESCRIPTION

Main unit is searching for the

sensor(s)

A channel has been found

Sensor 1 is sending data

The sensor cannot be found.

Search for the sensor or check

batteries

To search for a sensor:

Simultaneously, press and hold

MEM and CHANNEL for

2 seconds.

NOTE If the sensor is still not found, check the batteries,

obstructions, and remote unit location.

CLOCK

CLOCK RECEPTION

This product is designed to synchronize its date and time

automatically once it is within range of the WWVB-60

signal from the atomic clock in Boulder, Colorado.

The sensor collects the radio signals whenever it is within

1500 km (932 miles) of a signal.

NOTE Initial reception takes 2-10 minutes for first set up or

when RESET is pressed. Once complete, the reception icon

will stop blinking. If the signal is weak, it can take up to 24

hours to get a valid signal.
