REMOTE SENSOR
FEATURES
• Remote temperature transmission to the main unit via
433 MHz signal
• Case can be wall mounted using built-in hanger
• 100 feet (30 meters) transmission range without interference
• Selection of the temperature display in Celsius or Fahrenheit
BEFORE YOU BEGIN:
1 The remote sensor can be placed indoors or outdoors, the
main unit must be placed indoors.
2 We recommend using alkaline batteries for the remote
sensor and main unit when temperatures are above 32°F (0°C).
We recommend using AA lithium batteries for the remote
sensor when temperatures are below 32°F (0°C).
3 Avoid using rechargeable batteries. (Rechargeable batteries
cannot maintain correct power requirements).
4 Insert batteries before first use, matching the polarity in the
battery compartment.
5 ALWAYS install batteries in the remote sensor before the
main unit.
6 Press RESET after each battery change with a paper clip or
similar tool.
7 During an initial setup, place the main unit as close as
possible to the remote sensor.
8 After reception is established (the remote temperature will
appear on the main unit’s display), position the remote
sensor and the main unit within the effective transmission
range of 100 feet (30 meters).
NOTE:
1. Avoid setting manually the time and date on the main unit
before the remote temperature is displayed.
2. The effective operating range may be influenced by the
surrounding building materials and how the receiver and
transmitter are positioned.
3. Place the remote sensor so that it faces the main unit
(receiver), minimizing obstructions such as doors, walls,
and furniture.
4. Though the remote sensors are weather-resistant, they
should be placed away from direct sunlight, rain or snow.
NOTE: When the temperature falls below freezing, the
batteries in the outdoor remote sensors may have reduced
voltage supply and a shorter effective range. We recommend
using lithium batteries at temperature 32°F (0°C) and below.
A LED INDICATOR
• Flashes once when the remote sensor transmits a reading
to the main unit.
• Flashes twice when battery power is low.
B BATTERY COMPARTMENT
• Holds two AA-size batteries.
C WALL-MOUNT RECESSED HOLE
• Keeps the remote sensor on the wall.
D RESET
• Resets all readings.
E °C/ °F SWITCH
• Selects the temperature display in Celsius or Fahrenheit.
