4. Impostazione
4.1 Installazione della batteria
- Unità interna: Aprire il coperchio del vano batterie sul retro dell'unità principale. Inserire 2 batterie AAA, rispettando la polarità corretta (+/-). Chiudere il coperchio.
- Sensore esterno: Aprire il coperchio del vano batterie sul retro del sensore esterno. Inserire 2 batterie AAA, rispettando la polarità corretta (+/-). Chiudere il coperchio.
4.2 Accoppiamento dei sensori
The indoor unit and outdoor sensor should automatically pair once batteries are installed. If the outdoor temperature/humidity is not displayed after a few minutes, follow these steps:
- Assicurarsi che entrambe le unità abbiano batterie nuove.
- Place the outdoor sensor close to the indoor unit.
- Press and hold the 'CLEAR' button on the indoor unit for 3 seconds to clear previous data and initiate a new search for the sensor.
- If pairing fails, remove batteries from both units, wait 1 minute, and reinsert them.
4.3 Posizionamento
- Unità interna: Place the indoor unit on a flat surface using its retractable stand, or mount it on a wall using the hanging hole. Ensure it is away from direct sunlight, heat sources, or drafts that could affect readings.
- Sensore esterno: Mount the outdoor sensor in a shaded, dry location, protected from direct rain and sunlight, to ensure accurate readings. Avoid placing it near metal objects or large electrical appliances that could interfere with the wireless signal. The maximum effective range is 100m/328ft in an open area, but walls and obstacles will reduce this distance.
