STATUS DISPLAY - MAINS POWER FAILURE:
In the case of a power failure, the red LED flashes once every 2 secs. Parallel to
this, an acoustic alarm sounds. A mains power failure is displayed even when the
unit is switched off, but then without an acoustic alarm. This function is available if
the control is equipped with an emergency power supply accumulator.
