The key can be operated with a sharp object (paper clip, tip of a pen, etc. ) (single short pressing of the key). 3.

The HT78 measures the temperature directly and also receives the measurements of up to a maximum of 5 IROX thermo radio sensors. In the two information windows ) the temperature currently measured is displayed in °C (or °F).
