Key Features and Benefits

• Indoor and outdoor climate monitoring – displays indoor and outdoor temperature and relative humidity on a single screen for convenient environmental monitoring.
• Wireless outdoor sensor – transmits temperature and humidity data via 433 MHz radio communication over distances of up to 60 m in open areas, eliminating the need for cables.
• Support for up to 3 sensors – allows monitoring of several locations using two additional optional sensors. Sensor channels can be selected manually or displayed alternately.
• Weather forecast and barometric pressure – five animated weather symbols and an atmospheric pressure trend indicator help assess general weather developments over the next 12 hours.
• Indoor comfort and ventilation guidance – the DRY / OK / WET humidity comfort indicator and OPEN / CLOSED ventilation recommendations help determine when opening or closing windows may improve indoor conditions.
• Temperature alerts – adjustable upper and lower outdoor temperature limits trigger an audible warning. A frost symbol appears when the outdoor temperature is between –1 and +2.9 °C.
• Measurement history and trends – displays maximum and minimum temperature and humidity values, together with rising or falling trends. MAX/MIN values are automatically reset at midnight.
• DCF-77 radio-controlled clock – provides automatic time synchronisation, date and weekday display, two independent alarms and an adjustable snooze interval.
• Adjustable display illumination – three brightness levels are available during mains operation, while battery operation provides temporary backlighting.

Applications

The OAK weather station is intended for everyday indoor climate and local weather monitoring.

It is suitable for homes, offices, studies and other dry indoor environments. With optional additional transmitters, temperature and humidity can be monitored in different rooms or measuring locations.

The station helps users monitor indoor comfort, plan ventilation and follow general weather changes throughout the day.

Compatibility and Limitations

• Compatible additional temperature/humidity transmitter: TFA Dostmann 30.3253.02.

The display presents weather conditions, temperature, humidity, atmospheric pressure, time, date, moon phase and relevant status indicators.

Functions are controlled using SET/MODE, CH, ALERT, ALARM, + and – buttons, together with the touch-sensitive SNOOZE/LIGHT button.

When powered by the mains adapter, the backlight can remain continuously illuminated. During battery operation, the backlight can be activated for 15 seconds.

The outdoor transmitter has its own temperature and humidity display and a channel selection switch.

• The outdoor transmitter is splash-resistant but not waterproof. Install it in a shaded location protected from rain and direct sunlight.
• Keep the base station away from radiators, other heat sources and direct sunlight to avoid inaccurate temperature readings.
• Relative atmospheric pressure should be calibrated using local meteorological information before operation.
• Only use the supplied power adapter.
• Alkaline batteries are recommended.
• After replacing transmitter batteries, wireless pairing may need to be re-established.
