## Long description

tfa dostmann Casa White LCD is a compact indoor/outdoor weather station designed for home monitoring of room and external conditions.

The station provides weather icons and air pressure-based trend information to indicate changing conditions and synchronises the time via the DCF77 atomic clock signal.

How to use
Install AA 1.5 V batteries in the main unit and in the outdoor transmitter according to the polarity markings, then place the transmitter at the desired outdoor location within the wireless range. The station will automatically search for the transmitter signal on 0.433 GHz and display outdoor temperature and humidity when a stable connection is established. The internal sensors measure indoor temperature continuously while the DCF77 signal updates the displayed time. Use the device controls to view maximum and minimum values, enable or disable the backlight and set or acknowledge the frost alarm.
Usage recommendations
Place the outdoor transmitter in a shaded, well-ventilated position protected from direct rain and strong sunlight for representative temperature and humidity readings. Keep the main unit away from heat sources and drafts to ensure accurate indoor measurements. Replace batteries in both the station and transmitter promptly when low battery indicators appear to maintain reliable wireless transmission and time synchronisation.
