TEMPERATURE AND HUMIDITY INFORMATION IN A TWO LINE LCD DISPLAY D B C B. CHANNEL BUTTON • Selects the desired remote channel or indoor readings C. SEARCH BUTTON • Enforces the remote sensors signal search D. MEMORY BUTTON • Toggles between current, minimum and maximum readings of the indoor and remote temperature and humidity • Clears the maximum and minimum memory of registered temperature and humidity 5 REAR VIEW E F G E. WALL-MOUNT RECESSED OPENING H • Keeps the main unit on the wall F. BATTERY COMPARTMENT • Accommodates 2 (two) UM-3 or AA 1.5V alkaline batteries. G. C°/F° SWITCH (located inside the battery compartment) • Selects temperature display in Celsius or Fahrenheit H. UNFOLDING TABLE STAND • Supports the main unit on the flat surface 6 5 REMOTE SENSOR FEATURES • Remote temperature and humidity transmission to the main unit via 433 MHz signal • 100 feet (30 meters) transmission range without interference • LCD display of measured temperature and humidity • Three (3) channels selection • Selection of the temperature display in Celsius or Fahrenheit • Case can be wall mounted using built-in hanger A. LED INDICATOR • Flashes once when the remote sensor transmits a reading to the main unit. • Flashes twice when battery power is B. BATTERY COMPARTMENT • Holds two AA-size batteries C. RESET • Resets all readings D. CHANNEL SWITCH 7 • Selects the desired channel E. WALL-MOUNT RECESSED OPENING • Keeps the remote sensor on the wall F. °C/ °F SELECTOR • Selects the temperature display in Celsius or Fahrenheit BEFORE YOU BEGIN • The remote sensor can be placed indoors or outdoors; the main unit must be placed indoors. • 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). • Avoid using rechargeable batteries. (Rechargeable batteries cannot maintain correct power requirements). • Insert batteries before first use, matching the polarity in the battery compartment. • ALWAYS install batteries in the remote sensor before the main unit. • Press RESET after each battery change with a paper clip or similar tool. • During an initial setup, place the main unit as close as possible to the remote sensor. • 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). 8 7 NOTE: 1. Avoid pressing any buttons on the main unit before the remote temperature is displayed for about 2 minutes. 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 sensor may have reduced voltage supply and a shorter effective range. We recommend using lithium batteries at temperatures of 32°F (0°C) and below. BATTERY INSTALLATION REMOTE SENSOR NOTE: Install the batteries; select the channel and temperature in C° or F° before mounting the remote sensor. • Remove the screws from the battery compartment with a small Phillips screwdriver. • Set the channel. The switch is located in the battery compartment. Channel 1 is typically selected if only one remote sensor is being used. • Install 2 “AA” size alkaline batteries (not included) matching the polarities shown in the • Replace the battery compartment door and secure the screws. • Secure the remote sensor in the desired location. 9 MAIN UNIT • Open the battery compartment door. • Install 2 batteries (UM-3 or “AA” size 1.5V) matching the polarity as shown in the battery compartment. • Replace the battery compartment door. LOW BATTERY WARNING A low-battery indicator [ ] will appear on the indoor or remote temperature and humidity reading line of the main unit warning that the corresponding batteries need replacement. GETTING STARTED After batteries are installed; remote sensor will transmit temperature readings at 45 second intervals. The main unit may take up to two minutes to receive the initial readings. Upon successful reception, remote temperature will appear on the larger section of the main unit’s display (the default remote channel is channel one). The main unit will automatically update readings at 45-second intervals. If no signal is received from the remote sensor within two minutes, dashes [ - - - ] will be displayed. Press and hold the SEARCH button on the main unit for two seconds to initiate another signal CHECKING REMOTE AND INDOOR TEMPERATURE AND HUMIDITY The default display shows the and humidity information (temperature is on the top, and humidity is on the bottom line)...
