# Power consumption control
1 "5.6.1Permanent power limitation"[446]
▪ Allows you to limit the power consumption of the entire heat pump
system (sum of indoor unit and backup heater) with one permanent
setting.
▪ Limitation of power in kW or current in A.
2 "5.6.2Power limitation activated by digital inputs"[447]
▪ Allows you to limit the power consumption of the entire heat pump
system (sum of indoor unit and backup heater) via 4 digital inputs.
▪ Limitation of power in kW or current in A.
3 "5.6.4Current limitation by current sensors"[448]
▪ Allows you to limit the current of the household by limiting the current of
the heat pump system (sum of indoor unit and backup heater).
▪ Limitation of current in A.
4 "5.6.5BBR16 power limitation"[449]
▪ 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 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.
5.6.1 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.
