6.6.4 BBR16 power limitation
INFORMATION
Restriction: BBR16 settings are only visible when the language of the user interface is
set to Swedish.
NOTICE
2 weeks to change. After you activated BBR16, you only have 2 weeks to change its
settings ( BBR16 activation and BBR16 power limit ). After 2 weeks, the unit
freezes these settings.
Note: This is different from the permanent power limitation, which is always
changeable.
Use the BBR16 power limitation when you must comply with BBR16 regulations
(Swedish energy regulations).
You can combine the BBR16 power limitation with the other kW power
consumption controls. If you do so, the unit uses the most restrictive control.
