- Temperatuursensor: Measures the outdoor temperature.
- Transmissie-indicator: A small LED light that flashes when data is transmitted.
- Batterijcompartiment: Houses the batteries for the outdoor sensor.
- Kanaal wisselen: (Typically inside the battery compartment) Allows selection of a specific channel (1, 2, or 3) if using multiple sensors.
Instellen
- Plaats de batterijen in de buitensensor:
- Open het batterijvak aan de achterkant van de draadloze sensor.
- Plaats 2 AAA-batterijen (niet meegeleverd) volgens de polariteitsmarkeringen (+/-).
- Sluit het batterijvak.
- Note: If there is a channel switch inside the compartment, ensure it is set to Channel 1 for initial setup.
- Install Batteries in the Main Display Unit:
- Open het batterijvak aan de achterkant van het hoofddisplay.
- Plaats 2 AAA-batterijen (niet meegeleverd) volgens de polariteitsmarkeringen (+/-).
- Sluit het batterijvak.
- Het display licht op en begint te zoeken naar de buitensensor.
- De sensor koppelen:
- Place the outdoor sensor and the main display unit close to each other during the initial setup.
- The main unit should automatically detect and connect to the outdoor sensor within a few minutes. The outdoor temperature will appear on the display.
- If the outdoor temperature does not appear, press and hold the "CH" button on the main unit for 3 seconds to initiate a manual search for the sensor.
- Plaatsing van de buitensensor:
- Choose a shaded location for the outdoor sensor, away from direct sunlight and rain, to ensure accurate readings.
- Avoid placing it near heat sources (e.g., vents, appliances) or metal objects that could interfere with the wireless signal.
- The maximum wireless range is approximately 30 meters (100 feet) in open air. Walls and obstacles will reduce this range.
Bediening
Reading Temperatures
The main display unit shows the indoor temperature at the top and the outdoor temperature (from the wireless sensor) at the bottom. Both displays show the current temperature, along with the recorded high (HI) and low (LO) temperatures for the day, and a trend indicator.
Schakeltemperatuureenheden (°C/°F)
Druk op de ° C / ° F button once to switch between Celsius and Fahrenheit temperature units.
Clearing HI/LO Records
The thermometer automatically records the highest and lowest temperatures since the last reset. To clear these records and start new ones, press the DUIDELIJK button once. The HI/LO values will reset to the current temperature.
Kanaalselectie (voor meerdere sensoren)
If you are using multiple outdoor sensors (sold separately), you can switch between their readings by pressing the CH button. Each press will cycle through the available channels (e.g., CH1, CH2, CH3). Ensure each sensor is set to a unique channel via its internal switch.
Onderhoud
- Schoonmaak: Veeg de units af met een zachte, damp doek. Gebruik geen schurende reinigingsmiddelen of oplosmiddelen.
- Batterij vervangen: Replace batteries in both the main unit and the outdoor sensor when the low battery indicator appears on the display. Always replace all batteries at the same time with new ones of the same type.
- Opslag: If storing the thermometer for an extended period, remove all batteries to prevent leakage. Store in a cool, dry place.
