## Long description

The TFA SEASON (black/grey) is a compact indoor/outdoor weather station that displays temperature, humidity and barometric pressure with visual seasonal weather images. It measures indoor temperature from 0 to 37 °C and outdoor temperature from -40 to 60 °C, and reports outdoor relative humidity in the 10–99% RH range. The unit includes a built-in display with two brightness levels, a radio-controlled clock with weekday and date, and runs on a single AA alkaline battery. A separate wireless transmitter supplies outdoor temperature and humidity readings while the station shows pressure trends and a 24‑hour bar chart for quick weather assessment.
Advantages
The device combines multiple measurements—indoor/outdoor temperature, indoor humidity, outdoor humidity and atmospheric pressure—into one compact instrument with a clear built-in display. Seasonal weather images and weather symbols illustrate forecast changes based on barometric pressure trends, while the 24‑hour pressure chart helps track pressure shifts. Additional functions include alarm limits for temperature and humidity, daily max/min values, dew point and heat index calculations, and a moon phase indicator. Two display brightness levels and battery operation make it flexible for home, office or greenhouse placement.
Suitable for
Home monitoring of indoor comfort and energy-efficient heating/ventilation control
Office rooms where stable temperature and humidity tracking is required
Greenhouses or plant rooms where outdoor/indoor climate differences must be monitored
Hobbyists and small-scale weather observers who need a simple barometric trend and forecast

How to use
Install the wireless outdoor transmitter at the desired outdoor location and insert the AA battery into the main unit. Place the main station indoors where the built-in display is easily visible and avoid direct sunlight or heat sources to ensure correct indoor readings. The station receives outdoor sensor data wirelessly and updates temperature, humidity and pressure information on the display. Use the radio-controlled clock setting for automatic time and weekday synchronization. Configure alarm limits, max/min memory and preferred temperature units (°C or °F) via the device controls according to your needs.
Usage recommendations
For reliable outdoor readings mount the wireless transmitter in a sheltered, ventilated position away from direct sun, rain or snow. For accurate indoor climate monitoring avoid placing the main unit near radiators, kitchen appliances or windows with direct sunlight. Regularly replace the AA battery to maintain wireless reception and accurate time keeping.
