Product information

Description

TFA Horizon Black is a wireless indoor/outdoor thermometer-hygrometer that displays temperature and humidity trends and provides additional environmental information for home, office or greenhouse monitoring. The device measures indoor temperature and humidity and receives outdoor temperature via a 433 MHz radio transmitter. A built-in electronic barometer tracks air pressure and displays a weather symbol based on pressure changes; a bar chart shows air pressure history for the last 12 hours. The unit accepts AAA/AA 1.5 V batteries and has compact dimensions of 158×123×26 mm. The display also shows moon phase and sunrise/sunset times, and time and date are updated via the DCF77 atomic clock signal. The instrument includes alarm clock functions with two wake-up alarms and snooze, and a blue backlight that can be switched on with a button.

Advantages

TFA Horizon Black combines indoor humidity and temperature measurement with wireless outdoor temperature reception on 433 MHz, allowing coordinated monitoring of living climate and external conditions. The integrated electronic barometer and 12-hour pressure history chart support short-term weather forecasting with clear weather symbols. Compact size and battery operation make the unit flexible to install where needed, while DCF77 time synchronisation and dual alarms add everyday convenience. The front panel backlight improves display readability in low light.

Suitable for

  • Home rooms for tracking indoor climate and receiving outdoor temperature
  • Office spaces where compact monitoring of temperature, humidity and pressure is needed
  • Greenhouses and plant rooms where humidity and temperature trends are important
  • Cellars or secondary rooms when additional optional transmitters are used

Key specifications

  • Functions: indoor temperature, indoor humidity, outdoor temperature (via wireless transmitter), barometer with weather symbol, pressure history chart, moon phase, sunrise/sunset times, time and date display, dual alarm with snooze, backlight
  • Wireless transmission frequency for outdoor sensor: 433 MHz
  • Power supply: AAA/AA 1.5 V batteries (battery type supported)
  • Dimensions: 158 × 123 × 26 mm
  • Pressure history span: 12 hours (bar chart)

How to use

Place the main unit in a central indoor location within radio range of the outdoor transmitter. Insert the required AAA/AA 1.5 V batteries into the main unit and into the outdoor transmitter following manufacturer polarity markings. The device will receive outdoor temperature readings via the 433 MHz link and update indoor measurements continuously; pressure readings and the 12-hour chart update automatically. Time and date are synchronised via the DCF77 signal when available. Use the front panel buttons to view trend information, switch the blue backlight on, set the two wake-up alarms and activate the snooze function.

Usage recommendations

For reliable outdoor temperature reception, position the external transmitter in a sheltered location away from direct sunlight and heavy precipitation, and keep it within the recommended radio range of the main unit. Replace batteries in both the main unit and transmitter at regular intervals to ensure continuous measurements and time synchronisation.
