INFORMATION
In case more than 1 digital input is closed (at the same time), the digital input priority
is fixed: DI4 priority>...>DI1.
The outdoor unit has better efficiency than the electrical heater. Therefore, the
electrical heater is limited and turned OFF first. The system limits power
consumption in the following order:
1 Turns OFF the backup heater.
2 Limits the outdoor unit.
3 Turns OFF the outdoor unit.
Example
If the configuration is as follows: Power limitation level does NOT allow operation
of backup heater (step 1).

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 power consumption
controls. If you do so, the unit uses the most restrictive control.
