are short-circuited to start remote
operation.
Once this short circuit is established, ordinary
operation via the AT3 panel is disabled.

The maximum absolute rating is 50 V for voltage and 100 mA for current.
The recommended value is half or less of the rating.
In case of adding an inductor (e.g., relay), install a noise limiter (approx. 33 Ω + 0.1 μF), diode, or
the like.
