Default settings overview
16.6 Winter/summertime
Setting range: Auto/manual
Factory setting: Auto
The BM-2 has an integral perpetual calendar. This means that, when set to Auto,
the BM-2 switches automatically from summertime to standard time (wintertime) and
vice versa.
The changeover from standard time to summertime takes place on the last Sunday
in March at 01:00 UTC. In the Central European Time Zone, therefore, the clock is
put forward one hour from 02:00 CET to 03:00 CEST.
The changeover from summertime to standard time takes place on the last Sunday
in October at 01:00 UTC. In the Central European Time Zone, therefore, the clock is
put back one hour from 03:00 CEST to 02:00 CET.
If the BM-2 is being used in areas that do not follow these changeover rules (e.g.
Russia), the winter/summertime standard setting can be changed to "Manual" in the
default settings. With this setting, there is no automatic time changeover.
16.7 Minimum backlighting
Setting range: 5 % – 15 %
Factory setting: 10 %
The display will revert to minimum backlighting level if no further settings are made
on the BM-2 for one minute.
16.8 Screensaver
You can enable a screensaver. The display reverts to minimum backlighting after
one minute and the following values are shown:
f
Time
f
Outside temperature (outside sensor connected)
f
Room temperature (BM-2 installed in wall mounting base)
16.9 Key lock
The key lock prevents a unintentional adjustment of the heating system (e.g. by
children or when dusting). When the key lock is on, it is automatically enabled one
minute after the last setting is made.
ON = Key lock on
OFF = Key lock off
f
To temporarily override the key lock, press and hold the right rotary selector for
3 seconds.
16.10 User interface

CANNOT be used in conjunction with a CWL and the ISM7/8 i/e.
