# Power consumption control
3 "6.5.4 BBR16 power limitation" [

46]
▪ Restriction: Only available in Swedish language.
▪ Allows you to comply with BBR16 regulations (Swedish energy
regulations).
▪ Limitation of power in kW.
▪ Can be combined with the other kW power consumption controls. If you
do so, the unit uses the most restrictive control.
NOTICE
It is possible to install a field fuse with lower than recommended rating over the heat
pump. For this you must modify field setting [2‑0E] according to the maximum
allowed current over the heat pump.
Note that field setting [2‑0E] overrules all power consumption control settings.
Power limiting the heat pump will reduce performance.
NOTICE
Set a minimum power consumption of ±3.6 kW to guarantee:
▪
Defrost operation. Otherwise, if defrosting is interrupted several times, the heat
exchanger will freeze up.
▪
Space heating and DHW production by allowing the backup heater step 1.
6.5.1 Permanent power limitation
Permanent power limitation is useful to assure a maximum power or current input
of the system. In some countries, legislation limits the maximum power
consumption for space heating and DHW production.
