Remote control by text messages
The 4430 unit can be controlled remotely by sending text messages to the unit.
This can be done by a normal GSM phone.
The unit has a number of commands for guiding the process. Each command is different and contains a letter, which
assigns a property to the text message. In addition to letters, numbers 1 and 0 are used as abbreviations for the
ON/OFF function.
The setting can vary, but they are explained in this section.
Note that one text message can contain a combination of several commands.
General preconditions for sending a text message:
• Use the GSM phone and write your text message.
• Start the text message with the default code 1234, and then write the command.
• Send the message to the telephone number assigned to the SIM card of the 4430 unit.
