If you want to check, which unit is actually under operation, you may press again the << MODE >> button
shortly (less than 2 seconds) to get to the unit indication screen (Fig. 4-6). Here you can see in the upper
line the actual operating unit number ( 0 = unit 1, 1 = unit 2, 2 = unit 3). In the lower line you can see the
set switch over time value (e. g. 1 hour). No settings are available in this screen.

Don't forget to switch back to the main screen with temperature display (press << MODE >> button
several times until you see the green screen with the temperature display.
In case of any alarm occuring, the display will automatically jump to the red alarm display (Fig. 4-7) and an
alarm signal is output. During an alarm you can still go to the other screens. In the main screen however the
alarm will be displayed as long as there is an alarm present.
Following will cause an alarm:
• Set temperature limit is exceeded in case Alarm is set to "on"
• Any of the units outputs an alarm
In case any of the set temperature limits is exceeded, this alarm can be rest by simply pressing the
<<1/2/SET>> button.
In case any of the units outputs an alarm, that alarm can not be reset manually, it will automatically reset by
following conditions:
• All indoor units do not output an alarm any more (In that case there is a time delay to avoid loosing an
alarm too fast if someone switches the unit off, or if the unit is cycling to off. This alarm will only be reset, if
the unit switches back to on – either manually or by cycling control – and operates well for at least 15
seconds.)
