Wireless weather data transmission module for the seven weather data of the multi-sensor MS. With inner antenna. Standby loss of only 0.3 watts. For panel mounting. 45mm long, 45mm wide, 18mm deep. Supply voltage 24V DC from the 33mm low switched-mode power supply SNT61-230V/24V DC-0.25A, also 45mm long and 45mm wide. This switched-mode power supply simultaneously supplies the multi-sensor MS including the heating of the rain sensor. If necessary, place a deep flush-mounted socket together for both devices. This weather data transmission module receives the seven currently recorded weather data brightness (from three directions), twilight, wind, rain and outdoor temperature via cable J-Y (ST) Y 2x2x2x0.8 from the multisensor MS attached to the outside of the building once per second and sends these with the following priority as radio telegrams in the Eltako building radio. The evaluation is done with the building radio visualization and control software GFVS, the radio multi-function
