The Steca TA AF1 is a temperature sensor for recording the external temperature in weather-guided heating circuits. The recorded external temperature is transferred to the heating controllers Steca TH A603 M or Steca TH A603 MS, which then set the corresponding supply temperature.

In room guided heating circuits, Steca TA AF1 can be used optionally to display the external temperature.

A robust, impact-resistant casing protects the external temperature sensor against the effects of the weather.
