Commands can be triggered by a phone call. Number codes are not required for this.
The assigned command is run on calling a target number.
This procedure is secure and comfortable, as only calls from known phone numbers are executed and the functions can be entered directly as "name" in the phone book of a mobile telephone.
Speed dial and target dial buttons can be assigned (e.g. in office environments). Individual commands can be run from any workplace, as the target numbers and the phone number of the caller can be combined with each other.
For example, one single target number can be used for "Light ON" for all workplaces in an office. However, only the actuator of the workplace whose telephone number has been assigned is switched.
The list is edited using the control knobs to the right of it: Insert, Delete, Change/Edit
