4.1.6 Alarm functions
In emergencies, the unit can emit an alarm signal or even
actively deal with the problem by functioning in a special
mode.
This special operation replaces the normal operation of the
unit (during the day and at night time) until the signal is no
longer active (435 is 0 again).
